Basic flight theory

which force is caused by air pressure and friction differences?

• lift

• weight

• thrust

• drag

which force propels an aircraft forward?

• lift

• thrust

• drag

• weight

when thrust overcomes drag, an aircraft

• stays in place

• experiences stalling

• accelerate and move forward

• none of the above

What does increasing the aircraft's angle of attack do in terms of the forces it affects? Using that answer, what is the advantage and disadvantage of increasing the angle of attack?

Define the angle of attack

When an aircraft ascends,

• lift overcomes weight

• weight overcomes drag

• drag overcomes lift

• drag overcomes weight

which of the following can be used to explain how lift is generated?

• Newton's 1st law

• Bernoulli's principle

• Bernouni's principle

• Newton's 3rd law

Define aerofoil, and explain why it is used?

What happens when angle of attack is too large?
