WorksheetsPoF Chapter 7 Stall
Total questions: 15
Worksheet time: 8mins
A stall is caused by:
airflow separation
low airspeed
high angle of attack
low density
A typical stalling angle is
16 degrees
12 degrees
10 degrees
30 degrees
To recover from a wing-level stall:
angle of attack must be reduced
angle of attack must be increased
bank angle must be increased
density must be increased
An aircraft with swept wings:
stalls at the wing tip first and causes the aircraft to pitch up
stalls at the wing tip first and causes the aircraft to pitch down
stalls at the wing root first and causes the aircraft to pitch up
stalls at the wing root and causes the aircraft to pitch down
The stall speed for an aircraft with forward CG will:
increase
decrease
stay constant
decrease then increase
A lighter aircraft will stall:
at a slower stall speed
at a higher stall speed
at the same stall speed
at any speed
When an aircraft with rectangular wings stalls:
the CP moves aft and the aircraft pitches down
the CP moves aft and the aircraft pitches up
the CP moves forward and the aircraft pitches up
the CP moves forward and the aircraft pitches down
An aircraft with tapered wings stalls:
at the wing tip first
at the wing root first
at the leading edge first
at the trailing edge first
Stall strips are installed on some aircraft to:
induce stall at the wing root
induce stall at the wing tip
delay stall at the wing root
delay stall at the leading edge
At higher altitudes in normal operations, a large transport jet should never exceed a bank angle of:
15 degrees
20 degrees
25 degrees
30 degrees
Compared to a lighter aircraft, a heavier aircraft will stall:
at the same stall angle
at the same stall speed
at a slower stall speed
at a higher stall angle
An aircraft with a mass of 12,760 kgs has VS0 of 98 knots. The same aircraft with a mass of 9,276 kgs now has a new VS0 of approximately:
98 knots
84 knots
115 knots
76 knots
An aircraft with a wings-level stall speed of 76 knots. In a 60° angle of bank will stall at approximately:
91
76 knots
108 knots
82
An aircraft stalled and spun to the left.
The pilot should stop the spin by stepping on the left rudder.
The pilot should stop the spin by using elevator.
The pilot should stop the spin by rolling the aircraft to the right.
The pilot should stop the spin by stepping on the right rudder.
An aircraft with its centre of gravity towards the aft limit will:
stall at a higher stall speed
stall at a higher stall angle
spin at a flatter spin attitude
enter a spiral dive
