CPL De 12

Question 1

Critical engine failed, windmilling.

Answer 1

This is producing more drag then a geathered propeller and therefore produce more yaw.

Question 2

5 degree bank

Answer 2

Used to have zero sideslip + horizontal compononet of lift is helping to oppose the yaw

Question 3

Must unfavorable weight

Answer 3

Effect when airplane is banked. Weight increase, decrease vmc as we have more horisontal lift to stop the yaw.

Question 4

Must unfavorable c.g

Answer 4

Must aft C.G as the rudder is less effective because a shorter arm.

Question 5

Isa conditions, sea level

Answer 5

Higher density altitude decreases engine horsepower and lower VMC.

Question 6

Out of ground effect

Answer 6

Lift is less in ground effect, so out of ground effect our lift increase and therefore our drag.

Question 7

Gear up

Answer 7

Aircraft is more stable with gear down

Question 8

Take off flaps

Answer 8

Worst case is engine failure right after take off. So there fore take off flaps witch course more drag.

Question 9

Take off trim

Answer 9

Standarisation

Question 10

150 lbs of presure

Answer 10

Averge pilot

Question 11

Cowl flaps

Answer 11

Can be in open even tho it decrease vmc. Stabilze the aircraft.

Question 12

Maximum continous thrust

Answer 12

DA42 is the same as max thrust. Other engines will have max cotinous thrust.

Question 13

Nævn de 12:

Answer 13

Isa conditions, sea level
Must unfavorable weight
Must unfavorable cg
Take off trim
Take off flaps
Maximum continous thrust
Out of ground effect
Gear up
Critical engine failed, windmilling.
5 degree bank
150 lbs of presure
Cowl flaps

“Vi flyver på en ISA dag med dårlig vægt og CG. Sætter Takeoff trim og flaps, giver max power, flyver ud af ground effect, tager gear up, den kritiske motor dør, vi banker og giver 150lbs pressure til live engine. Cowl flaps”
