EFS 40/50 Electronic Flight Instrument System
The Bendix/King EFS 40 and EFS 50 are full-function EFIS systems that are compatible with a wide range of avionics systems. They feature unequaled clarity and brightness and meet FAA HIRF and lighting requirements.
The EFS 40's size, weight, price and performance, make it the first true EFIS system to be practical in many aircraft where larger, heavier, more costly EFIS systems are not feasible. The EADI displays are ED 462s. The EHSI can be the Ed 462 or ED 461. When the ED 461 (with built in mode control) is used, a CP 467 Control Panel is not required.
The Bendix/King EFS 50 is a full-function 5-inch EFIS. The EADI, EHSI and MFD displays are all fully interchangeable ED 551A's.
A 2-tube system uses a single SG 465 Symbol Generator, the 3-and 4-tube systems use two SG 465s and the 5-tube system uses three SG 465s. In systems with MFD, a CP 469A Control Panel is added. When an MFD is used in place of a weather radar indicator, a CP 466A/B Radar Control Panel is added. To simplify installation, the SU 463 Switching Unit is available. It serves as a master relaying device, reducing the number of external relays, wires and connectors.
