Understanding Airplane Control Surfaces

What is the primary function of the elevator in an airplane?

• To control the roll of the aircraft

• To increase the lift during takeoff

• To rise and lower the aircraft

• To control the yaw of the aircraft

Which axis does the rudder control in an airplane?

• Vertical or Y-axis

• Transverse axis

• Longitudinal axis

• None of the above

What is the role of ailerons in airplane control?

• To control the lift

• To control the roll

• To control the yaw

• To control the pitch

What is the center of gravity in an aircraft?

• Point where aerodynamic forces converge

• Point where the aircraft is most stable

• Point where weight is evenly distributed

• Point where lift forces are balanced

What do flaps primarily do on an airplane?

• Decrease the lift

• Control the yaw

• Increase lift and reduce speed

• Control the roll

In what type of aircraft are Krueger flaps typically found?

• Ultralight aircraft

• Large commercial airplanes

• Glider aircraft

• Light sport aircraft

What is the main purpose of slats in aircraft design?

• To increase drag during landing

• To decrease lift during takeoff

• To increase lift at low speeds

• To control the aircraft's roll

What function do spoilers serve on an aircraft?

• Increase speed during landing

• Decrease lift and slow down the aircraft

• Control the pitch of the aircraft

• Increase lift during takeoff

What are 'Elevons' used for in flying wings?

• To control both roll and pitch

• To decrease drag during flight

• To increase lift during landing

• To control yaw

Which control surfaces are mixed to form 'Flaperons'?

• Elevators and ailerons

• Flaps and ailerons

• Rudders and elevators

• Spoilers and slats
