Rolling is the rotation of the aeroplane about the (…) axis and controlled by (…).
Rolling is the rotation of the aeroplane about the (longitudinal) axis and controlled by (ailerons).
Pitching is the rotation of the aeroplane about the (…) axis and controlled by (…).
Pitching is the rotation of the aeroplane about the (lateral) axis and controlled by (elevators).
Yawing is the rotation of the aeroplane about the (…) axis and controlled by (…).
Rolling is the rotation of the aeroplane about the (normal or vertical) axis and controlled by (rudders).
Flight path angle is defined as the angle between (longitudinal axis/flight path vector) and (flight path vector/horizontal plane).
Flight path angle is defined as the angle between (flight path vector) and (horizontal plane).
Pitch angle is defined as the angle between (longitudinal axis/flight path vector) and (flight path vector/horizontal plane).
Pitch angle is defined as the angle between (longitudinal axis) and (horizontal plane).
An aircraft is approaching to land with its CG at the FWD limit. Compared to a situation with CG at the AFT limit, the control forces in pitch during the flare will be (higher/lower) and VREF would be (higher/lower).

Fairings of tail mounted engines give (positive/negative/zero) pitching moment.
Fairings of tail mounted engines give (positive) pitching moment.
- because of drag above the CG, so disregard thrust in this question! -
A T-tail has (more/less) stabilizing effect than a low tail due to receiving (more/less) downwash.
A T-tail has (more) stabilizing effect than a low tail due to receiving (less) downwash.
Full rudder deflection is limited on CAT aeroplanes as (IAS/altitude) increases becasue a full rudder deflection could in that case cause (an excessive load on the structure of the aeroplane/the aircraft to enter a spiral dive).

A Frise aileron is an aileron where the leading edge protrudes (below/above) the wing when teh aileron is raised, but not (below/above) it when the aileron is lowered.
A Frise aileron is an aileron where the leading edge protrudes (below) the wing when teh aileron is raised, but not (above) it when the aileron is lowered.
When an aileron is defelcted upwards, (induced/wave/interference/form) drag increases the most.
When an aileron is defelcted upwards, (form) drag increases the most.
Adverse yaw is the tendency of an aeroplane to yaw in the (same/opposite) direction of turn mainly due to the difference in (induced/form) drag on each wing.
Adverse yaw is the tendency of an aeroplane to yaw in the (opposite) direction of turn mainly due to the difference in (induced) drag on each wing.
An example of differential aileron defelction to initiate a left turn is left aileron (up/down) (2°/5°) and right aileron (up/down) (2°/5°).
An example of differential aileron defelction to initiate a left turn is left aileron (up) (5°) and right aileron (down) (2°).
If a turbulent gust causes an aeroplane to roll, the up-going wing experiences (an increase/a decrease/no change) in AoA.
If a turbulent gust causes an aeroplane to roll, the up-going wing experiences (an increase) in AoA.
A given aileron deflection affects (bank angle/roll rate) and is depentent on (IAS/TAS).
A given aileron deflection affects (roll rate) and is depentent on (IAS).
- Lift formula uses dynamic pressure which is IAS -
