Straight And Level Flight

Question 1

the forces acting on straight and level flight are:

Answer 1

weight and lift, thrust and drag

Question 2

an aircraft has to be in ___ ___ to be in straight and level flight

Answer 2

translational equilibrium

Question 3

weight acts through the ___ and lift acts through the ___

Answer 3

CoG, CoP of the wings

Question 4

the lift/weight couple creates a nose (up/down) pitching moment

Answer 4

down

Question 5

the thrust/drag couple creates a nose (up/down) pitching moment

Answer 5

up

Question 6

an increase in power increases the strength of the thrust/drag couple, creating a nose (up/down) pitching moment

Answer 6

up

Question 7

when lowering flaps, high-wing aircraft experience a nose (up/down) moment, while low-wing aircraft experience a nose (up/down) moment

Answer 7

up, down

Question 8

following an increase in speed during straight and level flight, the nose attitude will be (higher/lower) than before

Answer 8

lower

Question 9

for straight and level flight, thrust and drag must be equal, so the thrust required versus ias curve is the the same as the drag versus ias curve, true or false

Answer 9

true

Question 10

whats the equation for power required?

Answer 10

power required = drag x ias

Question 11

go look at the power available / power required curve GO

Answer 11

GO WTF LEAVE
