Open Ended

Why is it important to classify airplanes into civil and military categories?

Multiple Choice

Multiple Select

Which of the following are functions of the fuselage in an airplane?

• Houses the crew and controls

• Provides space for cargo and passengers

• Acts as the main lifting surface

• May house the engine

Open Ended

Explain how the design of the fuselage can vary depending on the mission to be performed by the airplane. Provide examples based on the types shown.

Multiple Choice

Which of the following is a conventional fuselage type?

• Winged

• Oval

• Lippisch's Aerodyne

• Burnelli UB-14

• Horten Ho-IX

• American Twin Mustang XP-82

Open Ended

Compare the fuselage designs of the Burnelli UB-14 and the Horten Ho-IX flying wing fighter concept. What are the key differences in their approaches to aircraft structure?

Multiple Choice

Which control surface is responsible for controlling the pitch of an aircraft?

• Elevators

• Ailerons

• Rudder

• Flaps

Multiple Choice

Match each aircraft movement (pitching, rolling, yawing) to its corresponding axis of rotation.

• Pitching - Lateral axis, Rolling - Longitudinal axis, Yawing - Vertical axis

• Pitching - Longitudinal axis, Rolling - Lateral axis, Yawing - Vertical axis

• Pitching - Vertical axis, Rolling - Longitudinal axis, Yawing - Lateral axis

• Pitching - Lateral axis, Rolling - Vertical axis, Yawing - Longitudinal axis

Open Ended

Describe the difference between primary and secondary flight controls and give examples of each.

Multiple Select

Which of the following are considered secondary flight controls?

• Flaps

• Trim Tabs

• Spoilers

• Ailerons

Fill in the Blanks

The rudder is used to control the

movement of an aircraft.

Open Ended

Explain how the ailerons control the roll movement of an aircraft.
