Aircraft and Flight Theory Worksheet

What is the primary force responsible for lifting an aircraft off the ground?

• The downward pull exerted by gravity on the aircraft's mass

• The aerodynamic force generated by air flowing over the wings

• The resistance created by air opposing the forward motion of the plane

• The thrust produced by the engine to propel the aircraft forward

Which force acts in opposition to thrust and slows an aircraft down during flight?

• The lift force pushing the aircraft upward against gravity

• The drag force resisting the aircraft’s motion through the air

• The gravitational force pulling the aircraft towards Earth’s surface

• The centripetal force acting during a turn or maneuver

The term “center of gravity” refers to:

• The point where lift equals drag for level flight

• The location where the total weight of the aircraft is considered to act

• The forwardmost part of the fuselage housing flight controls

• The vertical axis around which the plane yaws during turns

What does the term “yaw” describe in aircraft movement?

• Rotation of the aircraft around its longitudinal axis causing a roll

• Upward or downward tilt of the aircraft’s nose controlled by elevators

• Side-to-side movement around the vertical axis controlled by the rudder

• Forward acceleration produced by increasing engine thrust

The “theory of flight” primarily explains:

• How air pressure differences generate lift on wing surfaces

• The effects of engine power on maximum speed limits

Which control surface primarily manages an aircraft’s pitch?

• The rudder located on the vertical stabilizer

• The ailerons attached to the trailing edges of the wings

• The elevators mounted on the horizontal stabilizer

• The flaps extended from the wing’s leading edge

“Groundspeed” differs from “airspeed” because:

• It measures speed relative to the surrounding air mass

• It reflects speed over the earth’s surface, affected by wind

• It is only relevant during takeoff and landing phases

• It indicates the maximum speed achievable by the aircraft

What function does the “yoke” serve in most aircraft cockpits?

• It controls engine thrust and fuel flow during flight

• It acts as the primary control for pitch and roll movements

• It monitors the altitude and vertical speed of the aircraft

• It stabilizes the aircraft’s heading during crosswinds

Which of the following best describes a “stall” in flight?

• Loss of engine power due to fuel system failure

• A sudden drop in airspeed caused by a sharp turn

• Aerodynamic condition where lift decreases below weight

• A ground hold caused by air traffic congestion

The term “chocks” refers to:

• The instruments used to measure wind speed and direction

• Blocks placed in front of wheels to prevent aircraft movement

• Sections of the runway designated for emergency landings

• Signals from the control tower authorizing taxi clearance
