Vmc Conditions

Question 0

S

Answer 0

Standard day sea level. Standard day = high air density = improved engine performance = increase Vmc.

Question 1

Define Vmc.

Answer 1

Vmc is the minimum airspeed at which directional can be maintained with the critical engine inoperative.

Question 2

Ma

Answer 2

Max power on the operating engine.
More power from op engine creates yaw toward inop engine. More rudder required to maintain directional control. Improving op engine performance, increasing Vmc.

Question 3

C

Answer 3

Critical engine prop windmilling.
Windmilling: ^rudder. ^drag. ^Vmc
Feathered: _rudder. _drag. _Vmc

Question 4

F

Answer 4

Flaps take off position, gear up.
Landing gear and gear doors have a stabilizing keel effect. Decreasing Vmc.
Flaps down have a stabilizing effect, decreasing Vmc.

Question 5

U

Answer 5

Up to 5* bank.

Bank toward op engine increases horizontal lift + full rudder = lowered Vmc

Question 6

M

Answer 6

Most unfavourable weight and C of G.

Forward C of G = Increase in arm between C of G and rudder = ^rudder leverage = ^rudder effectiveness = _Vmc
