BUNPP-V (1479-V)

BUNPP-V 1479-V is a navigation and flight control amplifier unit used within the automatic flight control systems of Mi-8/Mi-17 family helicopters, including Mi-8AMT and Mi-8MTV-1. The device receives, amplifies and conditions electronic signals generated by onboard navigation and attitude sensors before passing them to downstream control circuits and actuators.

The unit operates as part of the AP-34B autopilot set, supporting aircraft stability channels and enabling automatic mode execution in flight and on the ground. BUNPP-V provides regulated signal gain, shaping and delivery to executive elements and assists in maintaining aircraft attitude and directional control under pilot-selected autopilot modes.

Power is supplied by the aircraft’s 27-V DC network and a three-phase 36-V, 400-Hz AC bus. The unit is designed for installation in avionics compartments and is rated for environmental conditions encountered in operational helicopter use. BUNPP-V belongs to certified aviation technical equipment (ATE) and fulfills a required role in automatic stabilization systems.
