M8.3 Aerodynamics Forces Relationship

What are the four fundamental forces that govern how an aircraft flies?

• Lift, Weight, Thrust, Drag

• Gravity, Friction, Pressure, Speed

• Lift, Gravity, Speed, Pressure

• Thrust, Pressure, Friction, Gravity

Which force must be greater than the aircraft's weight for it to take off?

• Drag

• Thrust

• Lift

• Weight

What is necessary for an aircraft to overcome to fly?

• Thrust

• Drag

• Gravity

• Lift

What is the relationship between thrust and drag during take-off?

• Thrust is less than drag

• Thrust is equal to drag

• Thrust is greater than drag

• Thrust has no effect on drag

What is the function of lift in an aircraft?

• To increase speed

• To counteract weight

• To reduce drag

• To enhance fuel efficiency

How is lift produced on an aircraft?

• By the engines pushing air

• By the motion of air flowing over the aircraft

• By the weight of the aircraft

• By the fuel consumption

What is the primary purpose of thrust generated by an aircraft's engines?

• To increase lift

• To overcome aerodynamic drag

• To reduce weight

• To stabilize the aircraft

What does aerodynamic drag do to an aircraft?

• Increases its speed

• Resists its motion through the air

• Stabilizes its flight

• Reduces its weight

What happens to lift when an aircraft increases its angle of attack?

• Lift remains constant

• Lift becomes zero

• Lift increases

• Lift decreases

What is the effect of increasing speed on the drag experienced by an aircraft?

• Drag decreases

• Drag becomes negligible

• Drag remains the same

• Drag increases
