DEVICE FOR SIGNALLING DEVIATION FROM GIVEN FLIGHT LEVEL AND GIVEN FLIGHT ALTITUDE OF AIRCRAFT Russian patent published in 2011 - IPC G05D1/00 

FIELD: physics, signalling.

SUBSTANCE: invention relates to aircraft construction and can be used in aircraft onboard equipment. To achieve the given result, the device additionally includes logic elements for controlling and showing the pressure level in the flight strip and corresponding functional elements which enable generation of auxiliary signals which are features for monitoring deviation from the flight level or from given altitude. The logic elements enable unblocking issuance of four warning signals - 'inadmissible deviation from given altitude', 'dangerous deviation from given altitude', 'deviation from given altitude' and 'deviation from the flight level'. The last two signals are meant for sound signalling.

EFFECT: broader functionalities.
