Q1. According to SERA, when two aircraft are approaching head-on at approximately the same altitude and there is a risk of collision, what action must each pilot take?

A. The heavier aircraft must descend and the lighter aircraft must climb.
B. Each aircraft must alter its heading to the right.
C. The aircraft on the right has the right-of-way and must maintain its course.
D. Each aircraft must alter its heading to the left.

Show answer & explanation

✓ Answer: B. Each aircraft must alter its heading to the right.

SERA.3210 specifies that when approaching head-on, or approximately so, each aircraft shall alter its heading to the right to ensure safe separation.

Q2. Moving the Centre of Gravity (CG) aft will have what effect on an aircraft's longitudinal static stability?

A. Increase stability and decrease control effectiveness.
B. Decrease stability and increase control effectiveness.
C. Increase both stability and control effectiveness.
D. Decrease both stability and control effectiveness.

Show answer & explanation

✓ Answer: B. Decrease stability and increase control effectiveness.

An aft CG reduces the arm of the horizontal stabiliser, decreasing its stabilising moment. This makes the aircraft less stable but more responsive to control inputs.

Q3. The tropopause is lowest over the poles and highest over the equator. This is primarily because:

A. The stronger centrifugal force at the equator pushes the atmosphere upwards.
B. The Earth's magnetic field compresses the atmosphere at the poles.
C. Intense and persistent convection at the equator pushes the tropopause to a higher altitude.
D. The greater mass of the polar ice caps gravitationally attracts the atmosphere.

Show answer & explanation

✓ Answer: C. Intense and persistent convection at the equator pushes the tropopause to a higher altitude.

The height of the tropopause is determined by the vertical extent of convection. Strong, deep convection in the warm, moist air at the equator forces the boundary between the troposphere and stratosphere to a much higher altitude (approx. 16-18 km) than at the cold, stable poles (approx. 8-10 km).
