Aircraft monitoring system

摘要

The system has a microphone connected to a cockpit voice recorder (5) and a central control module (1) with a power battery (3). It has connections to a cockpit activation switch (6), a cabin activation switch (7), a deactivation switch and a cockpit annunciator (8). A radio (10) is in communication with ground control and has several VHF channels (VHF 1-3). Two of these handle ATC tone control signals from ground control and one handles a transmitter line. The system may include a cockpit camera.
