Panel Mount unit used to display flight information
Uses a 4" color CRT & converts X/Y axis deflection signals & red-green-blue video signals from the symbol generators
Has no front panel controls & can be used as either an EHSI or EADI
When used as an EADI, the ED-462 will have inclinometer mounted on its front panel
Available in combinations of gray or black faceplate, 5 Vac, 5 Vdc, or 28 Vdc lightinging, with and without cooling fan, with and without inverted back (Note "Version Characteristics" table linked below)

Does the EFS-40/50 System support and interface with WAAS GPS?
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
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.

How does Southeast Aerospace calculate exchange prices and acceptable exchange cores?
Southeast Aerospace exchanges are based on the return of an undamaged, economically repairable core unit with identical part number as the unit shipped to the customer. An "economically repairable" core is defined as one where the cost to repair/overhaul (or Repair Cap) does not exceed 80% of the original SV/OH exchange price billed. Should the Repair Cap exceed 80%, the customer will be billed the additional amount. In the event this amount exceeds the Outright Price for the unit, the customer would only be billed the difference between the Outright Price and SV/OH Exchange Price with the core returned as-is to the customer.
Here is an example of such a transaction:
$1000 Exchange Price charged to customer
$1000 x .8 = $800 Maximum Allowable core repair charge or Repair Cap
$2000 Cost to repair core unit
- $800 Less Core repair cap
$1200 Additional billing amount.
2200.00 Total Cost of transaction
SEA offers exchange on new items as well. However, repair cap as indicated above is still based on SV/OH exchange price.
Are SEA's Exchange prices negotiable?
Negotiating the exchange price of a unit only limits the allowable repair cap for the core unit. Southeast Aerospace's exchange transactions are based on the return of economically repairable core unit. Once the core is received and evaluated, the core repair cost incurred by SEA cannot exceed 80% of the original exchange price. That is, it cannot cost SEA more than 80% of the original OH/SV exchange price collected from the customer. Therefore, when and if an SEA exchange price is discounted, there is a risk that additional charges may be assessed once the core is returned and evaluated.

Are there any special core requirements for an ED-461 or ED-462 exchange?
Yes, Service Bulletin 7 must be incorporated into the ED-461 and/or ED-462 otherwise an additional $5000 will need to be charged.
Although not mandatory, Service Bulletin 7 addresses a common weakness and failure point in the ED-461/462 units - the High Voltage Power Supply (HVPS). SB 7 incorporates a hardware modification with a new, improved HVPS that contains a better internal connector design. In order to provide a full warranty with the ED-461/462 units, SEA incorporates SB 7 into all units sold and exchanged.
Please note that ED-461 units with serial number 2604 and above contain SB 7 in the original production of the unit. ED-462 units with serial number 4346 and above contain SB 7 as well.
Why are exchange prices on EFIS indicators so high?
Most original EFIS tubes include older tube technology with a high voltage power supply (HVPS) and a CRT (cathode ray tube). Because units with CRTs can operate at high voltages they can be susceptible to significant failure. When failures in the power supply occur, they usually must be replaced. The failure can lead to problems in the CRT assembly itself as well.
In most cases, SEA exchange prices reflect the assumption that the HVPS will need to be replaced in the defective unit. Based on SEA’s historical data, approximately 75% of defective EFIS indicators will need to have the HVPS replaced but not necessarily the CRT. However, in most cases where the CRT must be replaced, then the cost is more than a replacement unit thus rendering the defective unit beyond economical repair (BER).
What are the common causes of EFIS indicator failures?
Most original EFIS tubes include older tube technology with a high voltage power supply (HVPS) that heats a CRT (cathode ray tube). Because units with CRTs can operate at high voltages they can be susceptible to significant failure. When failures in the power supply occur, they usually must be replaced. The failure can lead to problems in the CRT assembly itself as well. In most cases it is most cost effective to replace the unit with another serviceable unit when either the CRT or HVPS fail. In addition, the CRT is subject to screen burn in and needs to be replaced in order to be certified for use on an aircraft. Most manufacturers allow around 25% burn in before the CRT must be replaced.
