Straight And Level And Climbing Flight

Question 1

Thrust must equal

Answer 1

Drag + Wsin0

Question 2

Lift Must Equal

Answer 2

Lift = Wcos0

Question 3

Steady Climb

Answer 3

L = WCOS0
T = D + WSIN0

Weight is greater than lift
Thrust is greater than drag

Question 4

Descending Flight

Answer 4

D = Thrust + Wsin0
L = Wcos0

Weight is greater than lift
Drag is greater than thrust

Question 5

Maximum Range in glide is obtained by flying at

Answer 5

VMD

Question 6

Mass effect on gliding

Answer 6

Glide range independent of mass

Rate of descent - heavy aircraft higher airspeed therefore faster towards ground

Question 7

Headwind component on climb

Answer 7

Increase the flight path angle
Slower ground speed
Same airspeed
Shorter ground distance

Question 8

Tail wind component on climb

Answer 8

Decrease the flight path angle
Greater ground speed
Same air speed
Longer ground distance

Question 9

Flight path angle

Answer 9

Gradient related to ground distance (takes wind into account)

Question 10

Angle of climb

Answer 10

Relative to still air does not take wind into account
