1. A directional gyro consists of a:
(Note – the degree(s) of freedom of a gyro does not take into account its rotor spin axis.)
2. A directional gyro is valid only for a short period of time. The causes of this inaccuracy are:
1) Earth rotation
2) longitudinal accelerations
3) А/С motion over the Earth
4) mechanical defects
5) gyro mass
The combination regrouping all the correct statements is:
3. The indication of the directional gyro as an on-board instrument are valid only for a short period of time. The causes of this inaccuracy are:
1) The Earth’s rotation.
2) The longitudinal acceleration.
3) The aircraft’s motion over the surface of the Earth.
4) The mechanical defects of the gyro.
5) The gyro’s weight.
6) The gimbal mount of the gyro rings. The combination of correct statements is:
4. A Directional Gyro Indicator has:
