Display role in EFS 40/50 installations

BendixKing documentation describes EFS 40 as four-inch electronic instrumentation and EFS 50 as the related five-inch system. Depending on the approved system configuration and selected presentation, an ED 462 can display electronic attitude or horizontal-situation information and supported multifunction data. The displayed content is created by the associated symbol generator from valid aircraft inputs.

A typical chain is attitude, heading, navigation, flight-guidance, radio-altitude or weather-radar source → SG 465 symbol generator → ED 462 electronic display → crew. The exact sources and available pages depend on system wiring and software. A dark screen in the product photograph is the expected unpowered condition and must not be interpreted as a serviceability result.

Exact unit identification and construction

The authentic rear view identifies the product as an ED 462 Electronic Display with Part Number 066-03125-2600 and serial number 3705. TSO C113 is visible on the exact plate. The original chassis, rear connector, cooling fan, static-electricity caution label, mounting flange and four front mounting holes are preserved in the gallery photographs.

Reliable exact values for power consumption, overall dimensions, weight, connector pin assignment and environmental category were not independently confirmed from an authoritative open source for this -2600 suffix. These values should be taken from the approved ED 462 and EFS 40/50 installation data. No specification has been copied from an ED 461, ED 551 or visually similar display.

Cooling, installation and fault isolation

The rear photograph shows an integral fan and ventilation arrangement. Correct cooling is part of the installation and should not be blocked by wiring, insulation or foreign material. Before installation, confirm the panel cutout, mounting hardware, rear clearance, connector keying, power circuits, dimming, cooling airflow, SG 465 compatibility and approved display position for the aircraft.

Functional testing should verify power-up, brightness, color and geometry, mode selection, presentation of valid source data and annunciation of invalid inputs according to the EFS maintenance procedure. Display faults can originate in the ED 462, the SG 465, sensors, data buses, power supply, cooling or aircraft wiring. The complete signal path should be isolated before the display is removed.

The ED 462 must not be treated as interchangeable with another EFS display because the screen size looks similar. Compatibility depends on the complete suffix, symbol-generator software, aircraft wiring, connector, cooling arrangement and installation approval. A replacement or exchange should retain the modification and release information applicable to the serial-numbered unit.

Overhauled supply and ordering information

This 066-03125-2600 ED 462 is offered in Overhauled condition from partner stock with a six-month warranty. The listed price follows the agreed comparison with the exact same-condition public position. The quotation will confirm serial number, overhaul source, current display test, release certificate, modification status and any included connector or mounting accessory.
