Universal Standby Pendulum Indicator for Measuring and Alerting Attitude of Aircraft
摘要
The article reviews devices for determining the angular positions of fixed objects for various purposes and describes their operating principles. Options for using a mechanical liquid pendulum to determine the angles of inclination of moving objects, including the bank and pitch angles of aircraft, are considered. The principle of integration of a mechanical and electromechanical attitude indicator, combined with an alerting about the critical angles of bank and pitch of the aircraft, are presented. The procedure for removing an aircraft from a critical attitude position using visual and audio indicator messages is described.
