MACH ERROR
Position and Pressure
When, in flight, the needle of a needle-and-ball indicator is on the left and the ball on the right, the aeroplane is:
Turning left with too much LEFT rudder pedal
In a turn at constant rate, the turn indicator reading is:
inversely proportional to the aircraft true airspeed
The indication of the direction 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 The combination of correct statement is:
6) The gimbal mount of the gyro rings
The correct statements are:
1,3,4,6
For an EFIS equipped aircraft:
- The ND displays flight director command bars.
- The PFD displays the altimeter setting.
- The ND displays the attitude of the aircraft.
- The flight mode annunciator is part of the PFD.
The combination that regeoups all the corrects answers are:
2 and 4
A direction gyro is:
1) a gyroscope free around two axis
2) a gyroscope free around one axis
3) capable of self-orientation around an earth-tied direction
4) incapable of self-orientation around an earth-tied direction

270 Deg = too much nose up bank too high 2 equals too high
The magnetic heading can be derived from the true heading by means of a :
Isogonal lines are lines of equal Magnetic Variation on a map and can be used to determine Magnetic North from True North.
The quadrantal deviation of a magnetic compass is corrected by using :
