KRA-405B
FEATURES
2000 ft. display
28VDC, TSO'd
Internal 2500 ft. capability for use with ground proximity systems
Used with KNI-415 or KNI-416 indicators
Used with two KA-54 or KA-54A antennas
Provides analog and ARINC 429 outputs for increased interface capability including GPWS, TCAS, autopilot.
Option available with ARINC 552 auxiliary output (-0202 version)
Option available that can accept DH input from EFIS or KNI-415 or KNI-416 indicator to generate audio signal (-0202 version)
Version available that provides enhanced accuracy (+-2 feet) below 100 ft. using digital 429 buss labels 164/465 (-2001 version)
Version available with capacitor (C3) on the RF board changed to dampen frequency response of the high altitude intermediate (IF) receiver filter to low frequencies; RF absorber attenuates stray RF to prevent false low altitudes caused by vibration; 2 thermal conductors change harmonic resonance of the logic and power supply board (-4001 version)
Version available to have lower receiver sensitivity than -4001; adds extra margin against possibility of a false low altitude indication when flying above the normal lock range of the rad alt; intended for Dassault FX7 installations with multi-path, low-level reflections or interference that compromises antenna isolation (-5001 version)
