M8.2 Aerodynamic resultant

What happens when thrust equals drag?

• The aircraft flies at a constant airspeed

• The aircraft accelerates

• The aircraft decelerates

• The aircraft ascends

What is the role of the Angle of Attack (AOA) in flight?

• It helps maintain level flight by adjusting lift

• It changes the color of the aircraft

• It increases the number of passengers

• It decreases the weight of the aircraft

How can some aircraft change the direction of thrust?

• By changing the wing shape.

• By pivoting the engines or vectoring exhaust gases.

• By altering the aircraft's color.

• By increasing the aircraft's weight.

What happens if the angle of attack (AOA) is increased too much?

• The aircraft will speed up.

• The aircraft will stall.

• The aircraft will descend.

• The aircraft will turn left.

What is the relationship between lift and vertical speed when lift becomes less than weight?

• Vertical speed will increase.

• Vertical speed will decrease.

• Vertical speed will remain constant.

• Vertical speed is irrelevant.

What can some aircraft with a thrust-to-weight ratio greater than one do?

• Fly vertically

• Fly horizontally

• Hover in place

• Glide without power

What is the direct result of the relationship between the relative wind and the aircraft?

• Weight and thrust

• Lift and drag

• Thrust and lift

• Drag and weight

What force opposes the motion of an aircraft moving through the air?

• Lift

• Weight

• Thrust

• Drag

What is the effect of increasing the aircraft's speed on lift?

• Lift decreases

• Lift remains constant

• Lift increases

• Lift becomes irrelevant

What happens to drag when the angle of attack is increased?

• Drag becomes zero

• Drag increases

• Drag remains the same

• Drag decreases
