BAP-1

BAP-1 is an aircraft emergency and warning signal unit used as part of the SAS-4-9 crew alerting system. The unit receives, processes and outputs emergency and caution signals from aircraft systems and provides visual and audio alerts in the cockpit to warn the flight crew of failures and abnormal operating conditions.

BAP-1 accepts discrete input signals from aircraft relay circuits and system sensors, analyzes each connected channel and sends logic commands to annunciator panels, a central warning light and interface elements of the SAS-4-9 system.
The unit supports up to 30 independent input circuits, allowing wide monitoring coverage of aircraft systems.

BAP-1 is designed to operate from the aircraft 24–29.4 V DC power supply, and maintains functionality under degraded power conditions down to 18 V, ensuring system availability during emergency electrical states.
The unit is installed on aircraft equipped with the SAS-4-9 annunciation system including Yak-42, Il-86 and compatible platforms.

Depending on configuration, BAP-1 can be supplied with or without a mounting frame.
The unit is intended for continuous duty operation as part of onboard avionics.
