The KMD-540 display used in the KMD-550 and KMD-850 Multi Function Display systems is capable of receiving magnetic from several sources. This heading information is used to correct the difference between heading and track based display pages to allow overlay of flightplan information and other data. Compatible heading sources include synchro XYZ, FMS/HDG, Traffic ARINC 429, digital heading via WX-500 Stormscope. According to the KMD-550/850 installation manual, synchro XYZ is the highest priority heading source. However, the KAC-504 traffic PCMIA card must be installed in the KMD-540 base unit for the XYZ heading to operate. Therefore, this card must be installed in the KMD-540 display to interface common heading systems such as the Collins PN-101 and Bendix/King KCS-305 & KCS-55A. The cost of the KAC-504 traffic card is $2000 list price. Click Here to view a page from the KMD-550/850 installation manual detailing these interfaces (Adobe Acrobat Reader required). The KMD-540 will utilize position information from many GPS or FMS sensors. It can be configured for either RS-232 or ARINC 429 as the position source depending on the PCMIA card configuration in the KMD-540. That is, the ARINC 429 source option requires the installation and configuration of the KAC-504 traffic card option in the KMD-540. Most GPS receivers output RS-232 information. This includes common receivers such as the Bendix/King KLN-89B / KLN-94 / KLN-90B / KLN-900, Garmin GPS-400 / GNC-420 / GNS- 530 / GPS-150XL / GPS-155 / GPS-155XL / GPS-165 / GNC-250 / GNC-250XL / GNC-300 / GNC-300XL and UPS/II Morrow GX-50 / GX-55 / GX-60 / GX-65. Flight Management Systems such as the Bendix/King GNS-X / GNS-XLS and the Universal UNS-1A, 1B, 1K only output ARINC 429 information. In addition all Garmin receivers and the Bendix/King KLN-90B, KLN-900 will output both RS-232 and ARINC 429 formats. Please note that if the KAC-504 card is installed, Honeywell recommends that the ARINC 429 source be used if available. Click Here to view a page from the KMD-550/850 installation manual detailing these interfaces (Adobe Acrobat Reader required). The KAC-504 card was used for the above interfaces because of its extended expansion capabilities (inputs and proessor). The other interface cards available for the KMD-540 do not have expansion potential. As of 7/1/02, Honeywell is reporting that WX-1000E Stormscope interface may be the next interface available for the KMD-540 via the KAC-504 card.
On July 26 2001, UPS Aviation announced that a software/hardware upgrade would be available to enable the UPS/IIMorrow line of GPS receivers (GX series and SL series) to be compatible with the ST-901 GPSS converter and System 55X Autopilot. The software upgrade will cost $395 to non database subscribers and $295 to database subscribers. A $995 &black box& will be required for this conversion of RS-232 signal output from the UPS units to the ARINC 429 standard required for the GPSS unit. For more information on this upgrade, please click Here.
FDE is an algorithm that monitors the accuracy and reliability of GPS signals, detects erroneous GPS data, and excludes that data from the active navigation solution. Unlike Receiver Autonomous Integrity Monitoring (RAIM), which will terminate GPS navigation if signal integrity is compromised, FDE actively enables the pilot to continue navigating with GPS technology. FDE offers an increased level of safety to pilots flying over the Atlantic or Pacific or in remote areas where navigation aids are scarce. Most GPS receivers that are found in trans-oceanic aircraft will have provisions for the FDE. Therefore, most handheld GPS units and lower end GPS receivers will not have FDE.
RAIM is a software algorithm that is available in some GPS receivers which gives an indication if the position accuracy of the GPS receiver is suitable for use. The RAIM availability (or ability of a GPS receiver to provide a RAIM warning) is dependent on the number of satellites available or in view by the GPS receiver. A minimum of five satellites is required to provide a RAIM warning. If there are less than 5 at any point in time at some location then this is identified as a &RAIM hole& (or RAIM unavailability). GPS receivers that also provide RAIM prediction do not take into account GPS satellites that have been taken out of service for maintenance by the United States Department of Defense.
Wide Area Augmentation System or WAAS is a navigation system developed by the FAA to improve the accuracy, integrity, and availability of the Global Positioning System (GPS). The purpose of WAAS is enable aircraft to utilize on GPS navigation for all phases of flight including precision approaches.

WAAS uses a network of ground-based reference stations, located inside airports within North America and Hawaii, to measure small variations in GPS signals in the western hemisphere. The measurements are sent to master stations which send the correction messages to the WAAS satellites every 5 seconds or less. These satellites then broadcast the corrected signal back to Earth where a WAAS-enabled GPS receiver uses the corrections to compute its position with improved accuracy.

WAAS allows a precision approach to be published for any airport. Because of the improved accuracy of each GPS satellite's information, aircraft equipped with WAAS GPS are allowed to fly at lower en-route altitudes than was possible with ground-based systems.
The GPS receivers originally manufactured by UPS Aviation Technologies - SL40, SL60, GX50, GX55, GX60 only accept serialized RS-232 altitude information from an encoder. Therefore, they will not accept standard gray code information. Altitude code converters such as the 3000U are available to convert gray code from an existing, standard encoder to serialized data for the UPS GPS receivers.
Please note that these pros and cons are drawn in relation to the comparison of the two units only. GPSMAP 295 Pros: More portable than Skymap IIIC, can operate from AA batteries Database can be updated by user via PC update cable and computer disk Optional Mapsource CD and storage cartridge allows for alternative uses. For example, Metro CD allows for street level mapping which is very useful for vehicular purposes. Most accessories included as standard items (i.e. remote antenna, mount, PC cable, cigarette adapter, etc.) Split HSI / moving map screen Display fields can be easily changed GPSMAP 295 Cons: 4& diagonal display Horizontal display only= limited viewing area in front of aircraft, inconvenient yoke mount placement Portable use only; cannot be mounted in panel of aircraft; cannot interface with other avionics Skymap IIIC Pros: 5& bright TFT display Can be used as portable GPS or can be mounted in or on panel of aircraft via optional rack/panel mount. This allows for integration of unit to other avionics such as autopilot (via optional interface module). Joystick data entry allows for easy point selections Has outputs to interface with other avionics such as autopilot (with use Avionics Interface Module) and external GPS receivers Provides output for external alarms or annunciators Skymap IIIC Cons: Bulky and somewhat cumbersome compared to GPSMAP 295 Display can be configured vertically or horizontally Can only be operated with external power source such as cigarette adapter in aircraft Database cannot be updated by user via PC. Database cards must be exchanged. In addition, back cover must be removed to change database card No CD option or street level mapping capabilities Display fields are fixed and cannot be changed
Basic RNAV defines European RNAV operations which satisfy required track keeping accuracy of +-5 nautical miles for at least 95% of the flight time. The term &basic& can be considered to equate to the expression RNP 5 (Required Navigation Performance) which is a statement of the navigation performance accuracy necessary for operation in a defined airspace. Thus N-RNAV = RNP 5 RNAV. Most GPS receivers produced today satisfy this requirement for receiver accuracy. Most older GPS units have software modifications or service bulletins available to bring the GPS unit up to this specification.
In very general terms, RAIM (Receiver Autonomous Integrity Monitoring) and FDE (Fault Detection and Exclusion) are means to provide a GPS receiver with a cross check function and exclusion of an unreliable satellite for navigation purposes.
In VOR navigation, there is a flag on most CDIs that will warn pilots when a VOR signal is not valid or not available. RAIM provides the means for the GPS receiver to indicate a problem with a satellite. FDE then checks each satellite against each other and exclude the failed satellite when a problem is detected.
RAIM is always required in GPS receivers that are certified to TSO C129A or better. This certification, in most cases, allows the GPS receiver to be operated and utilized for IFR navigation.
If a GPS receiver has the FDE feature, then, in most cases, it may be used as the sole navigation source in oceanic and remote flying operations. Information such as dates, times, route, waypoint, speed, etc is entered by the pilot into the GPS or FMS to make the necessary FDE prediction to determine sufficient satellite availability, integrity, and accuracy for the FDE flight plan. These predictions are made possible due to the known, published orbits of the satellites around the Earth. That is, if the GPS knows where each satellite is going to be located in the sky on each part of a flight plan, then it can make the necessary adjustments and exclusions on which satellites to use or not use.
Wide Area Augmentation System (WAAS) is essentially a system of satellites and ground stations that provide GPS signal corrections providing better position accuracy. GPS receivers must be WAAS capable to provide better position accuracy which can result in accuracy of better than three meters 95% of the time. WAAS consists of 25 ground reference station positioned across the USA that monitor GPS satelitte data. Two master stations collect data from the ref stations and create a GPS correction message. This corrected message is broadcasted one of two geostationary satellites, or satellites with a fixed position over the equator. The information is compatible with the basic GPS signal structure which means any WAAS-enabled GPS receiver can read the signal. For some users in the U.S., the position of the satellites over the equator makes it difficult to receive the signals when trees or mountains obstruct the view of the horizon. WAAS signal reception is ideal for open land and marine applications. Currently, the GPSMAP 295 is the only Garmin handheld GPS that is WAAS capable. The WAAS function can be enabled in the Setup menu of the GPS. The GPSMAP 295 must have software version 2.20 or higher to have WAAS satellite support. Software updates for the GPSMAP 295 can be obtained at Garmin web site by clicking Here

Under certain conditions, the Garmin 400W/500W series units will not provide serial heading information to the L3 WX-500 Stormscope. Even if the WX-500 unit is wired for synchro heading, there may be issues with the WX-500, GDL-69 datalink, and crossfill between two Garmin units. Also, some issues have been encountered with the COM flip/flop key not switching between the active and standby frequencies. As of 8/20/07, Garmin plans to resolve these issue with the next software release. The software upgrade should be able to be completed at your local Garmin authorized facility.

For handheld GPS receivers, database updates can be ordered and downloaded directly through Garmin's Internet site.

For panel mount GPS receivers, all database cards and computer downloads (if applicable) must be ordered through Jeppesen. Contact Jeppesen at www.jeppesen.com for more information.

No, the KI-207 does not have an OBS resolver so the OBS mode in the GPS will not function with it. The KI-207 is intended to be a repeater indicator.
Extended Squitter (or 1090 ES) is the Mode S transport protocol for ADS-B operation. 1090 MHz extended squitter is an ADS-B link for air carrier, commercial, and private aircraft. With 1090ES, the Mode S transponder supports an extended squitter (ES) message. Currently, this message provides position, velocity, and heading information.

The ES versions of the Garmin GTX33, GTX-330, and GTX-330D transponders comply with FAA TSO C-166A which dictates the minimum performance standards (MPS) for 1090 MHz ADS-B equipment. Existing Garmin GTX Mode S transponders without ES can be upgraded through Garmin to include the Extended Squitter feature. On average the Extended Squitter option costs an additional $1000-$1500 USD.

It is very important to note that in order for the ES data to be broadcasted, the transponder must be interfaced to a compatible GPS that meets TSO C145a/C146a. These TSOs explains the performance standards for WAAS GPS receivers. As of 2009, the CNX80, GNS480, GNS400W/500W series and G1000 are the only Garmin GPS receivers that meet this criteria.
No. Previous Garmin GPS receivers such as the GPS-155 and GPS-155XL included navigation guidance for search-and-rescue (SAR) operations. This allowed users to navigate in a ladder pattern to maximize coverage in an area by referencing 2 anchor waypoints. You could then enter a leg increment value or distance between the legs of the waypoint.

The GNS430/430W does not include this SAR function.
No, technically a WAAS GPS is not the only GPS receiver that can be interfaced to a certified ADS-B Out system. Most WAAS GPS receivers provide all of the parameters and meet all of the performance requirements needed for an approved ADS-B Out system. Therefore, due to the popularity and availability of WAAS GPS receivers, most aircraft will be utilizing them in approved ADS-B systems.

The Garmin HTAWS or Helicopter Terrain Awareness is only available for Garmin WAAS GPS receivers. The added GPS integrity, quality, and performance that WAAS GPS provides is needed to facilitate the helicopter terrain functions. Therefore, an original GNS430, GNC420, GPS400, GNS530, or GPS-500 navigator must be upgraded to WAAS or "W" status before HTAWS can be incorporated.

Unfortunately, the GPS in the KMD-150 does not comply with any of the requirements for GPS performance in the latest ADS-B mandate or DO-260B. More or less, although it is not specifically referred as such, current WAAS GPS receivers are the only GPS receivers that meet the performance requirement needed for ADS-B Out.

Considering your current situation, here are a few possible scenarios for you to comply:

  1. Keep the KMD-150 with GPS as a stand-alone navigation aid and pursue the KGX-150 with internal GPS. This would of course require installing a separate WAAS GPS antenna on your aircraft for the KGX-150. In addition, you would not receive any of the ADS-B In benefits since the KMD-150 is not an interface for that. However, there are many options to display ADS-B In information on anything from smartphones, tablets, etc.
  2. Replace the KMD-150 with some sort of Garmin GNS or GTN navigator which will meet the approved position source requirements for ADS-B. I would recommend their GDL-84 or 88 boxes for the UAT portion of the equation however there are a few other manufacturers offering less expensive UAT solutions like Free Flight with their Ranger Lite product.


The second option is obviously going to be more expensive but gives you a little more versatility and more capability in your aircraft. I only included UAT (978) options because I am assuming that you are flying below 18,000 feet.

Check back often for even more ADS-B information. Need ADS-B Help?

Yes, the RANGR Lite is meant for owner/operators who do not have an ES (Extended Squitter) upgradeable transponder or WAAS GPS in their aircraft. The less expensive unit (TXL) is Transmit only while the other (XVRL) includes ADS-B In as well which will display (traffic and weather) on the GNS-430 but would be need to be interfaced.

First, we would recommend contacting a local Garmin dealer to discuss the following:

  • Upgrading your existing nav/com to a used GNS-530W or the newer GTN-750.
  • If you already have a Garmin transponder (i.e. GTX-330), then you should simply get the ES upgrade, interface to GNS-530W or GTN-750, along with a few other minor installation considerations, and get the shop to do the appropriate paperwork based on Garmin's AML STC.
  • If you do not have the GTX-330, then you should just consider pursuing one of the GDL systems from Garmin. Most likely the GDL88 which will give you In/Out capability. Same interface and installation considerations as above apply. Please note ADS-B In is not required for the mandate.

UPDATE

5/9/2018

Bendix/King, L3 and ACSS released the NXT-700/MST-70B as form fit replacement for the MST-67A. It is DO-260B compliant to meet the ADS-B Out mandate.

There are other options besides the MST-70B to gain ADS-B compliance. There are various STCs that allow the removal of the Bendix/King transponder system and installation of Rockwell Collins or Garmin transponders. Upgrade prices vary depending on actual installed equipment. 

Regarding ADS-B for the Garmin GTX-330 transponders, the best solution is to simply have the units converted by Garmin to include the ES (Extended Squitter) upgrade. This upgrade is about $2000 approximately. Additionally, a WAAS/GPS source will need to be interfaced. We can process the upgrade for you or any other Garmin dealer can as well.

First, please reference the information Garmin provides in relation to the ES upgrade:

http://www.garmin.com/us/intheair/ads-b/seven-questions/

There is perhaps a misconception that simply having your Garmin GTX-330 transponder upgraded to include Extended Squitter capability is the only step for ADS-B Out compliance. As with almost all ADS-B installations, appropriate interfacing to other systems in the aircraft (ex. approved position source & altitude source) is required along with approved guidance material that indicates the airworthiness approval procedure followed for return to service of the aircraft (ex. AML STC). Garmin provides an Installation Manual with Approved Model List STC for its Aviation dealers. Authorized dealers should not be distributing the necessary data and paperwork for the ADS-B installation to non-dealers.

As with all ADS-B installations, Southeast Aerospace strongly recommends that you only contact and consult a trained, authorized avionics dealer.

No. Southeast Aerospace strongly recommends that you only contact and consult a trained, authorized avionics dealer for all ADS-B installations.

One of the reasons for much of the confusion, controversy, and misinformation surrounding ADS-B is due to those in the aviation realm who are minimalizing or ignoring key aspects of an ADS-B installation. Most if not all ADS-B installations are not a “box-swap” regardless of any advertising or information on the Internet stating as much. Even if you were to seek alternate, unauthorized methods to obtain ADS-B equipment or upgrades to existing equipment, you still need a way to get it in the aircraft and approved by the FAA. Most ADS-B product manufacturers only offer AML STCs they have to authorized dealers in their network.

If you want to be compliant and able to fly in 2020, then just get the job done right the first time. Unfortunately, some people in aviation always try to cut corners on avionics installations by underestimating the job at hand in hopes to save a buck. It never works out to your advantage no matter how it looks on the bottom line on the frontend of the job. The old saying holds true for ADS-B installations especially – “Pay Now or Pay Later”.

If you want your installation done right the first time legally and technically, then contact a trusted avionics shop that has formal training on ADS-B and the related products from the OEM. Or, contact the OEM and ask for a recommendation in your area. Most OEMs are more than happy to refer to a legitimate, quality dealer in your area.

Citation S550 equipped with: Transponders MST-67A 066-01143-2101. Chance to update to ES?

Garmin GPS400. Chance to update software to WAAS? Or maybe to replace with a GPS400W and link it with transponders? - FMS UNS-1L SCN 803.1. Citation Mustang C510 equipped with G1000 Integrated Flight Deck. It is a 2008 plane.

What can I do to get ADS-B at an affordable price?

A: Since the aircraft are operated in Spain, what region or ADS-B spec do you need to meet? (i.e. USA, DO-260B?)

Without knowing exactly what ADS-B requirement or mandate you might be trying to comply with, I can only provide information relative to what we know here in the USA in reference to ADS-B for Part 25 aircraft.

For the Citation 550, the MST-67A will be superseded by the MST-100B if/when Honeywell can produce and certify the MST-100B. I have attached the only details that we currently have on the MST-100B. Honeywell has not even released pricing on this unit yet, however, ideally it would be an ideal solution ultimately since it is said to be plug and play with the MST-67A. With a WAAS GPS interfaced it would meet all ADS-B mandates. Also, keep in mind, that your CAS-67 can be upgraded fairly easily to Change 7.1 via Honeywell sales bulletin upgrading the TPU-67A processor to the TPU-67B. There is a company that offers some STCs for Part 25 aircraft if your region requires an STC for the 7.1 upgrade - http://www.prostaraviation.com/

If the MST-100B does not pan out for some reason and/or Honeywell keeps delaying its release, then there is a company named Jettech that has released Garmin GTX 3000ES ADS-B capable transponder to its existing STC covering Garmin GTN install on Citation and Citation Jet aircraft equipped with TCAS II. In addition, the company amended its Garmin GTN autopilot coupled LPV FAA STC for the Citation 500 series to include all Primus 1000 equipped Bravo, Ultra, Encore and Excel aircraft. They do not have much information on their website about the ADS-B STC but I recently learned about it at the AEA convention last week - http://jettechllc.net/index.html

Regardless of what direction you might go in, you should most likely get your GPS-400 upgraded to the GPS-400W while Garmin is still offering the upgrade. It is relatively inexpensive at around $3000 USD. Most FANS type systems will require WAAS GPS input or accuracy ultimately. Plus, Garmin's WAAS interface tis very compatible with most ADS-B solutions. Regarding the Citation Mustang C510 equipped with G1000, Garmin is still working on this solution. We assume it will include the GTX-3000 transponder(s) as this aircraft will require a 1090 MHz, (not 978 MHz UAT) system. I would continue to monitor Garmin's website for announcements relating to the G1000.

In most cases, if you already have Garmin equipment, the easiest route to comply with ADS-B is to stay with Garmin. Based on what you gave me below, you would need to upgrade your GNS530 to the 530W (WAAS) and replace your GTX327 with the GTX330ES (Extended Squitter). Most shops will give you a trade-in value for the GTX327 and there are some used GTX330ES units out there on the market. This route will make you compliant with the 1090ES part of ADS-B compliance.

Otherwise, if you choose to keep the GTX327 and go with the GDL88 or GDL84 UAT (978 compliance), you will still have to get your GNS530 upgraded to WAAS and then handle some additional considerations.

Unfortunately, the GPS in the KMD-150 does not comply with any of the requirements for GPS performance in the latest ADS-B mandate or DO-260B. More or less, although it is not specifically referred as such, current WAAS GPS receivers are the only GPS receivers that meet the performance requirement needed for ADS-B Out.

Considering your current situation, here are a few possible scenarios for you to comply:

  1. Keep the KMD-150 with GPS as a stand-alone navigation aid and pursue the KGX-150 with internal GPS. This would of course require installing a separate WAAS GPS antenna on your aircraft for the KGX-150. In addition, you would not receive any of the ADS-B In benefits since the KMD-150 is not an interface for that. However, there are many options to display ADS-B In information on anything from smartphones, tablets, etc.
  2. Replace the KMD-150 with some sort of Garmin GNS or GTN navigator which will meet the approved position source requirements for ADS-B. I would recommend their GDL-84 or 88 boxes for the UAT portion of the equation however there are a few other manufacturers offering less expensive UAT solutions like Free Flight with their Ranger Lite product.


The second option is obviously going to be more expensive but gives you a little more versatility and more capability in your aircraft. I only included UAT (978) options because I am assuming that you are flying below 18,000 feet.

A few questions related to the KGX 150 :

  1. Can this unit be paired with the KT-76C transponder?
  2. What will the Wi-Fi option cost?
  3. With our configuration, what antennas will need to be installed to meet the ADSB-Out requirements?
  4. Will an additional antenna be required to facilitate ADS-B-In?

There are a few things to be aware of with all UAT installations. These units require a control device and a switch to place them in air/ground mode. The switch is not a major issue and is a minor cost. However, the controller is additional if the aircraft is not already equipped with a transponder and/or display (MX20 for example).

As you’ll see below, yes, the KT-76C will pair with the unit via the antennas. Basically the UAT will sense the XPDR. This will enable you to send the Mode A and IDENT information to the UAT unit. However, you are still required per the FAA to have a way to know your ADS-B status. If a suitable display such as the Garmin MX20, Aspen EFD1000 or the KSN 770 is not installed, then a remote control unit is required. The KGX Control Panel list price is currently $619. Depending on the aircraft and the kind of flying, there are a lot of factors and options to consider.

  1. Can this unit be paired with the KT-76C transponder?
    • Yes
  2. What will the Wi-Fi option cost?
    • The Wi-Fi option will run around $349 list for parts.
  3. With our configuration, what antennas will need to be installed to meet the ADS-B-Out requirements?
    • Per the STC, you will be required one external WAAS/GPS antenna and at least one UAT antenna.
  4. Will an additional antenna be required to facilitate ADS-B-In?
    • No, as long as the unit purchased is the transceiver. However, you will need a suitable display for the "In" without the Wi-Fi.

In regards to your RV-6A, upgrading to the GTX 330ES will take care of your 2020 requirements for ADS-B. As you already have a GTX 327 and a GNS 430W, you may be more pleased with the installation of a GDL 88 standard. The prices of the units are similar even once you add the new antenna for the GDL-88 (give or take about $150). The labor to install the GDL 88 will be more, but with the GDL 88 you will get free weather and traffic on the GNS 430W. This would then free up the Garmin 696 and the GDL 39 for your Luscombe.

In regards to your 1947 Luscombe 8-E, your options are not as straight forward. You have no WAAS/GPS receiver in the aircraft so one of the UAT units like the GDL 88/84 from Garmin, NGT-2500 from L-3, or the RANGR 978 from Freeflight will be your best option to give the ADS-B Out. The RANGR 978, with its control head (required per the installation manual), may be the least expensive option but all three will have a fair amount of labor for the installation.

Since SEA is a Rockwell Collins dealer, we can perform this modification. Some of the equipment for this modification can be sold in serviceable condition, but we cannot sell factory new without performing the upgrade ourselves. There are several components required to perform this modification as well as wiring changes and additions. We’re happy to discuss this modification in more detail with you and gather the information necessary to provide you with an accurate proposal.

Portable ADS-B Out systems, also known as "suitcase" units, should not be operated (transmitting) aboard any aircraft. While marketing associated with these units may imply approval for use by way of an FCC license, the FAA prohibits their use for the following reasons:

  1. The positioning of portable, suction-cup GPS antennas associated with these units often require they be affixed to front or side windows or glare shield to obtain a usable signal. Such antenna placement obstructs the pilot's view. Connecting wiring also interferes with aircraft controls and instruments.
  2. ADS-B Out avionics require a valid Mode S code to be transmitted to operate properly with ATC automation and other ADS-B aircraft. Mode S codes, also known as the ICAO code, are assigned to an aircraft during registration and then programmed into transponders and ADS-B Out avionics. Mode S codes remain static until a change in aircraft registration or identification (N-number) occurs. Portable units require users to input the Mode S code assigned to each aircraft flown. A high number of Mode S code entry errors have occurred with this procedure, which prevent proper target correlation within ATC automation systems (target drops/traffic conflict alerts), which have resulted in increased workload and unnecessary distractions for pilots and controllers.
  3. The positioning of ADS-B antenna is also vital in the quality of the signal that is transmitted, and if capable, received by the ADS-B device. There have been a number of aircraft identified using portable ADS-B devices that result in degraded performance due solely to poor antenna location.

The KLN-94 is not a WAAS GPS, nor is it upgradeable to one. We recommend the KT-74, but if you decide to upgrade to a GPS400W or GNS430W, then you would want to go with a GTX-330.

The FAA Rebate program has come to and end. Please reference the FAA's webite for more information. https://www.faa.gov/nextgen/equipadsb/rebate/faq/#q0201

Other discount opportunities include the following:

1. Fleet or multiple aircraft discounts. Many avionics shops will offer significant discounts for multiple aircraft ADS-B upgrade committments. 

2. Avionics vender sales bulletin special pricing. Avionics venders will, from time to time, come out with special pricing on specific equipment or equipment combinations. Sometimes the equipment pricing is tied to certain airframes. Avioncs shops often times pass these special pricing opportunites on to the customer. Special pricing bulletins always have an expiration date for equipment ordering and shipping so be mindful that pricing can change drastically if you do not commit. 

3. Avionics upgrades beyond ADS-B. When performing ADS-B upgrades along side of EFIS, Radio, or other upgrades discounts can be extended due to aircraft access and equipment bundle pricing. 

BendixKing announced a modification to the CitationJet CNI 5000 using the KT-74 transponder and a remotely mounted WAAS GPS receiver. A package including the hardware, modified bezel, and STC will be available to authorized dealers. Please contact Southeast Aerospace to discuss ADS-B and upgrade options for the CitationJet.  See photo below. Alternatively, there are existing STCs that allow the installation of Garmin GTN navigators in the CNI 5000 location. The GTN can then control remote mounted GTX 3X5R transponders for ADS-B Out and In. 

 

CNI 5000 ADS-B

 

There is no ADS-B In display option for a Honeywell MFRD. An iPad or other Flight Bag is the only option.
