Description

Technical Field

[0001] The utility model relates to the field of flight teaching aids, in particular to an attitude instrument flight teaching aid. Background Art

[0002] The attitude indicator is an instrument that indicates the pitch and roll status of the fuselage during flight, so that the pilot can timely understand and grasp the pitch and roll angles of the aircraft and ensure that the pilot can correctly operate the aircraft. In ground teaching, the parameters displayed by the attitude indicator in different flight attitudes are simulated to improve the students' ability to correctly judge and accurately control.

[0003] When existing pilots are taught on the ground, simulation teaching aids can be used to achieve pitch and tilt flight simulation. However, when common simulation teaching aids are used, they mostly simulate the parameters displayed by the attitude instrument in different flight attitudes. Parameters cannot be set arbitrarily for simulation teaching, and there is no simulation display of upright and inverted flight attitudes, which easily reduces the simulation teaching effect of the pilot using the attitude instrument.
