Quiz on Principles of Flight and Aerodynamics

What are the four forces acting on an airplane?

• Weight, Lift, Thrust, Drag

• Gravity, Lift, Thrust, Friction

• Weight, Drag, Thrust, Friction

• Lift, Drag, Thrust, Gravity

What is the purpose of understanding basic aerodynamics for pilots?

• To increase fuel efficiency

• To enhance communication with air traffic control

• To ensure safety and control of the aircraft

• To improve navigation skills

What happens when a wing exceeds the critical angle of attack?

• The wing stalls

• The wing increases drag

• The wing maintains lift

• The wing produces more lift

Which principle explains that faster-moving air has lower pressure?

• Equal Transit Time

• Kutta Condition

• Bernoulli's Principle

• Newton's Law

What is the effect of flaps on a wing's camber?

• They delay stall

• They reduce weight

• They increase drag

• They decrease lift

What is the primary cause of wake turbulence?

• Wingtip vortices

• Weight distribution

• Engine thrust

• Air resistance

What is the relationship between load factor and stall speed?

• Higher load factor decreases stall speed

• Load factor only affects drag

• Higher load factor increases stall speed

• Load factor has no effect on stall speed

What is static stability in an airplane?

• The ability to maneuver easily

• The tendency to return to original flight attitude

• The ability to maintain altitude

• The response to pilot inputs

Which of the following is a type of parasite drag?

• Lift-induced drag

• Induced drag

• Skin friction drag

• Form drag

What does the term 'angle of attack' refer to?

• The angle between the wing and the horizon

• The angle between the chord line and relative wind

• The angle of the airplane's climb

• The angle of descent during landing
