Question 7

Apparent wander

Answer 7

apparent wander = 15° • sin(lat°)

apparent wander in degrees per hour

Question 8

In Air-Driven Artificial Horizons, a turn through 270° gives (correct pitch indication/an apparent climb) and (correct/under-/over-)​ indication of bank.

Answer 8

In Air-Driven Artificial Horizons, a turn through 270° gives (an apparent climb) and (over-) indication of bank.

Question 9

Transport wander

Answer 9

transport wander = chlong • sin(mean lat°)

• transport wander in degrees (total)*
• chlong = change in longitude [x°]*

Question 10

At a low bank angle, the measurement of rate-of-turn actually consists in measuring the (roll/yaw/pitch) rate of the aircraft.

Answer 10

At a low bank angle, the measurement of rate-of-turn actually consists in measuring the (yaw) rate of the aircraft.

Question 11

Angle of bank in rate one turn

(rule of thumb)

Answer 11

Angle of bank in rate one turn = (TAS ÷ 10) + 7

• Angle of bank [x°]*
• TAS = true airspeed [kt]*
• Rate One Turn = 3°/s*

Answer 13

During a left turn while taxiing on the ground, the pointer on the turn indicator will point towards the (left) and the ball will be on the (right) hand side.

Question 14

A directional gyro consists of a (one/two) degrees of freedom (horizontal/vertical) axis gyro.

Answer 14

A directional gyro consists of a (two) degrees of freedom (horizontal) axis gyro.

Question 15
