As of September 2017, the Garmin G5 electronic flight instrument is not a replacement for the KI-256 flight command indicator. 

 

The DG/HSI version of the G5 can interface to a variety of autopilots such as the King KFC-150/200 to provide heading and course error to the autopilot.  The G5 can interface to select autopilots for coupled flight in heading and nav modes with a compatible navigation source.

well.  The KI-256 is not simply an attitude gyro/indicator.  It supplies attitude data to KFC autopilots and is a flight director as

For the G5 DG/HSI version with nav interface (PN K10-00280-30), only Garmin nav/GPS radios will interface to the G5.  This includes the Garmin GNC-255 series, SL30, GNS-430/530 series, and GTN-650/750 series navigators.

As of June 2017, the G5 has not been approved as the standby instrument in the G1000 cockpit.

As of June 2017, the Garmin G5 (all versions) do not have the ability to interface to an autopilot.

A counter drum altimeter displays altitude using a single pointer and a rotating drum that displays digits. The drum displays ten thousand and one thousand foot increments. The pointer displays from 0 to 999 feet. Counter drum pointer altimeters are commonly found on commercial aircraft.

Yes but there are installation factors to consider. It is very enticing to overwhelmingly consider the Garmin GTR-225 radios over the BendixKing KY radios since the Garmin radios can be puchased at a fraction (50%+) of the cost of the BendixKing radios. We are referring to New radios not used/reconditioned. However, it should be noted that the Garmin radios are approximately .3 inches higher than the KY radios. The rear mount cutout height for the KY radios is 1.30"; front mount is 1.35". The Garmin GTR cutout is 1.65" for rear mount and 1.77" for front mount.

Aircraft On Ground or AOG is a term used in aviation indicating that a problem exists that prevents an aircraft from flying. It implies a heightened urgency to acquire parts or service to allow the aircraft to be put back into service and prevent further delays.

The KX-155 and KX-165 LED display upgrade involves more than simply changing a display assembly as it was with the original gas discharge displays
manufactured in the KX-155 and KX-165 radios.

Southeast Aerospace recommends the Mid-Continent TC230 step up converter. The TC230 takes in 10-18 VDC and outputs 28 VDC at 230 watts output power. It weighs less than 1 pound and is compact in size.

Bendix /King recently announced a GPS/WAAS Display upgrade for the EFIS-40 &
EFIS-50 systems on the TBM 700 & PC-12 aircraft. The Symbol Generator
Software (SW) Modification (MOD) 15/01 will enable the EFIS 40/50 system to
display the correct WAAS vertical deviation when GPS is selected as the
navigation source and connected to a WAAS enabled GPS receiver via an ARINC
429 interface. This allows the KFC-325 autopilot to remain coupled to the
EFIS system display when flying an LPV.

The upgrade also allows autopilot enabled output and display of lateral
deviations and vertical guidance while on other WAAS GPS approaches.

Separate annunciations may be required to support WAAS, depending on the GPS
installation and supporting STC. The upgrade is applicable to EFIS 40/50 SG
465 Symbol Generators on the TBM 700 and PC-12 aircraft having Part Numbers
066-04021-1108 throug h -1114. The applicable SG 465 part numbers will be
converted to P/N: 066-04021-1115.

Upgrade list price: $5,000. Southeast Aerospace will also be offering
upgrade exchanges for non-WAAS units. Please
Contact SEA for details on exchanges.

Click on a question below to see the answer. Please note, as more questions are answered, this document will be updated to include them.
Check back often for even more ADS-B information. Need ADS-B Help?

A: Starting September 19, 2016, the FAA is offering a limited time, first-come, first-serve rebate for owners that meet the criteria. The detailed rebate information & process can be found on the FAA's ADS-B Rebate webpage.

"Beginning this month, the FAA will issue 20,000 rebates on a first-come, first-served basis for one year or until all 20,000 rebates are claimed - whichever comes first. The rebate is available only to owners of US registered, fixed wing, single engine piston aircraft that were first registered before January 1, 2016.

Aircraft owners who have a standard airworthiness aircraft may have a repair station or an appropriately-licensed A&P mechanic install the ADS-B equipment. Owners of aircraft certified as experimental or light sport must adhere to applicable regulations and established standards when installing ADS-B equipment.

Owners are only eligible for the rebate if they install the avionics after September 19, 2016, and within 90 days of the rebate reservation date. Aircraft owners will have 60 days after the scheduled installation date to validate their equipped by flying their aircraft, and will then be able to claim the rebate."

A: 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. http://www.freeflightsystems.com/products/ads-b/978/rangr-transmitter 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.

A: 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

1/24/2017

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

A: In relation to ADS-B compliance for the MST-67A, Honeywell is developing the MST-100B. Please see attached brochure. Unfortunately, this is the only information that Honeywell has released regarding the MST-100B. Pricing and lead-time are to be announced sometime later this year by Honeywell. Regarding other options for the MST-67A, there are a few companies in the US that are developing solutions using the new Garmin GTX-3000 remote transponder.

Regarding ADS-B for the Garmin GTX 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. We can process the upgrade for you or any other Garmin dealer can as well.
A: 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.
A: 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.
A: 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.

A: 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.
A: 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.
A: 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.

A: 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.

A: 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 GNS340W, then you would want to go with a GTX-330.
A: There is no ADS-B In display option for a Honeywell MFRD. An iPad or other Flight Bag is the only option.
