R/T RAD ALT STD TRIP (P/N alt-55b) - As Removed

The alt-55b is a Collins Aerospace radio altimeter receiver/transmitter providing low-range above-ground-level (AGL) height data for aircraft flight displays and warning systems. Operating to approximately 2,500 feet above terrain, this unit supplies altitude information to GPWS (Ground Proximity Warning System) and ALI-55/DRI-55 indicator interfaces. Installation requires proper antenna configuration and wiring per aircraft maintenance manual specifications.

The alt-55b integrates with radar altimeter systems on general aviation and business aircraft, delivering critical terrain clearance data for approach and landing phases.
