What is the difference between the KRA-10 P/N 066-1061-01 and KRA-10A P/N 066-1061-03 radio altimeter receiver/transmitters?
The KRA-10A includes an optional altitude inhibit function. When connected to a strut or speed switch, the KRA-10A will prevent the KI-250 needle from being in view when there is a possibility of reflections from nearby objects while taxiing on the ground. The KRA-10 does not have the optional altitude inhibit feature.
