Aerodynamics, Forces and Flight

What is weight in aviation?

• Weight is the force of gravity acting on an aircraft, pulling it downward.

• Weight is the total mass of an aircraft including passengers and cargo.

• Weight is the lift generated by the wings of an aircraft.

• Weight is the distance an aircraft can travel without refueling.

What controls the yaw motion of an aircraft?

• The ailerons

• The elevator

• The rudder

• The flaps

What is the role of elevators in an aircraft?

• Elevators control the roll motion of the aircraft, allowing it to bank left or right.

• Elevators control the yaw motion of the aircraft, allowing it to turn left or right.

• Elevators control the pitch motion of the aircraft, allowing it to climb or descend.

• Elevators are used to stabilize the aircraft during turbulence.

What happens when thrust is greater than drag?

• The aircraft will speed up.

• The aircraft will slow down.

• The aircraft will maintain a constant speed.

• The aircraft will descend.

How does drag affect an aircraft's speed?

• Drag increases the aircraft's speed, especially when flying with the wind.

• Drag has no effect on the aircraft's speed.

• Drag slows the aircraft down, especially when flying against the wind.

• Drag only affects the aircraft during takeoff and landing.

What is the effect of increased speed on lift?

• Increased speed decreases lift, causing the aircraft to descend.

• Increased speed has no effect on lift.

• Increased speed generally increases lift, allowing the aircraft to rise.

• Increased speed only affects lift at low altitudes.

What is the significance of the angle of attack?

• It is the angle between the wing and the oncoming air; it affects lift and drag.

• It determines the speed of the aircraft.

• It is the angle between the aircraft's nose and the horizon.

• It measures the weight of the aircraft.

What is the purpose of flaps on an aircraft?

• To increase fuel efficiency during flight.

• To increase lift at lower speeds, helping the aircraft take off and land.

• To reduce noise during takeoff and landing.

• To improve the aircraft's speed in cruise flight.

What is the role of ailerons in an aircraft?

• Ailerons control the roll motion of the aircraft, allowing it to tilt left or right.

• Ailerons are used to control the altitude of the aircraft.

• Ailerons help in increasing the speed of the aircraft during takeoff.

• Ailerons are responsible for the aircraft's navigation system.

What is the relationship between lift and weight?

• Lift must be less than weight for an aircraft to ascend.

• Lift must be equal to weight for an aircraft to ascend.

• Lift must be greater than or equal to weight for an aircraft to ascend.

• Lift has no relationship with weight in aircraft flight.
