Which type of stability refers to the tendency of an aircraft to return to level flight after a disturbance in roll?

• Static stability
• Dynamic stability
• Longitudinal stability
• Lateral stability

What effect does a low aspect ratio wing have on stability?

• Increases stability
• Decreases stability
• No effect on stability
• Decreases stability during landing

What is the primary function of the tail rotor on a helicopter?

• Generates lift
• Controls pitch
• Provides stability
• Counters torque produced by the main rotor

The concept of aerodynamic stall in aviation refers to:

• Loss of engine power at high altitudes
• Loss of lift due to exceeding critical angle of attack
• Loss of control during turbulent weather conditions
• Loss of airspeed during descent

The Lateral axis of an aircraft runs:

• From wingtip to wingtip
• From the nose to the tail
• From left to right
• From top to bottom

What is the primary advantage of a winglet on an aircraft's wing?

• Increase in wing area
• Reduction in induced drag
• Increase in parasitic drag
• Enhancement of engine performance

What design feature helps mitigate the effects of ground resonance in helicopters?

• Skid landing gear
• Shock absorbers
• Rigid rotor system
• Tail rotor guard

What is the primary danger associated with ice formation on an aircraft's wings and control surfaces?

• Loss of cabin pressure
• Decreased engine efficiency
• Loss of lift and control
• Increased drag

What is the purpose of the aircraft's ice detector?

• To detect ice formation on critical aircraft surfaces
• To detect air temperature and humidity
• To detect ice formation in the fuel system
• To detect ice formation at the engine intake

What is the difference between anti-icing and de-icing?

• Anti-icing prevents ice formation, while de-icing removes ice after it forms
• Anti-icing removes ice after it forms, while de-icing prevents ice formation
• Anti-icing is used on wings, while de-icing is used on engines
• Anti-icing is used on engines, while de-icing is used on wings
