Aerospace Notecards 1-3

What are ailerons used for in a fixed-wing aircraft?

• To control roll

• To control pitch

• To control yaw

• To increase lift

What is an airfoil designed to do?

• Increase drag

• Provide stability

• Give a favorable ratio of lift to drag

• Control yaw

What do aircraft control surfaces include?

• Wings and fuselage

• Ailerons, elevators, and rudders

• Engines and propellers

• Landing gear and flaps

What does the Angle of Attack (AOA) refer to?

• The angle between the wing and the tail

• The angle between the chord line of the airfoil and the direction of the oncoming air

• The angle of the aircraft's nose to the horizon

• The angle of the landing gear to the ground

What does Bernoulli's Principle explain?

• How lift is generated

• How pressure decreases as the velocity of a fluid increases

• How drag is minimized

• How temperature affects flight

Where is the Center of Gravity (CG) located in an aircraft?

• At the nose of the aircraft

• At the tail of the aircraft

• Where the total weight of the aircraft is considered to be concentrated

• At the wings

What is the purpose of flaps on an aircraft's wings?

• To decrease lift

• To increase lift and drag at low speeds

• To control yaw

• To stabilize the aircraft

What does the horizontal stabilizer provide?

• Lift

• Thrust

• Stability in pitch

• Control of roll

What does the lapse rate measure?

• The rate of fuel consumption

• The rate of speed increase

• The rate at which atmospheric temperature decreases with an increase in altitude

• The rate of engine thrust

What force directly opposes the weight of an aircraft?

• Thrust

• Drag

• Lift

• Gravity
