Where is low pressure found in relation to a wing during flight?
Below the wing
Above the wing
At the wingtip
At the trailing edge
How does an aircraft stall?
When the airspeed is too high
When the angle of attack exceeds the critical angle
When the aircraft is overloaded
When the flaps are fully extended
How can a pilot increase lift to climb to a higher altitude?
Decrease the angle of attack
Increase the angle of attack or airspeed
Reduce airspeed
Deploy landing gear
What is the function of the flaps on an aircraft?
To increase speed
To increase lift and drag
To decrease weight
To stabilise the aircraft
How does aircraft weight reduce during flight?
By jettisoning cargo
Due to fuel consumption
By shedding parts
Through aerodynamic lift
What are the two types of drag experienced by an aircraft?
Frictional and gravitational drag
Induced and parasite drag
Thermal and mechanical drag
Static and dynamic drag
What is an example of parasite drag?
Drag from the wing's lift
Drag from the aircraft's fuselage
Drag from the landing gear
Drag from the tail fin
What is ground effect in aviation?
Increased drag when flying at high altitudes
Increased lift and reduced drag when flying close to the ground
Decreased lift when flying over water
Increased turbulence when flying near mountains
What is the primary purpose of ailerons on an aircraft?
To increase lift
To control yaw
To control roll

What happens to the lift generated by a wing as the angle of attack increases beyond the critical angle?
Lift is unaffected by the angle of attack
Lift decreases and the wing stalls
Lift increases indefinitely
Lift remains constant
What is the primary factor that affects the lift generated by an aircraft wing?
Engine power
Altitude

Which aerodynamic force acts opposite to the direction of flight?
Thrust
Lift
Drag
Weight
What is the effect of deploying spoilers on an aircraft wing?
Increase lift
Decrease lift and increase drag
Increase speed
Stabilize the aircraft

Drag is unaffected by speed
Drag remains constant
Which part of the aircraft is primarily responsible for generating lift?
Fuselage
Wings
Landing gear
Tail
What is the effect of increasing the angle of attack on an aircraft wing before reaching the critical angle?
Drag decreases
Lift increases
Lift decreases
Weight increases
Which part of the aircraft is primarily responsible for controlling roll?
Rudder
Flaps
Ailerons
Elevators
What happens to the lift and drag when flaps are extended during landing?
