Question 1

Manufacturers determine VMCA under the following conditions:

Answer 1

COMBATS

1. Critical engine inoperative
2. Operating engine operating at maximum continuous power
3. Maximum gross weight/Least favorable gross weight
4. Bank angle up to 5 degrees
5. Aft CG
6. Takeoff configuration (gear up, cowl flaps closed, carb heat off)
7. Standard day (59 degrees F/15 degrees C, 29.92 Hg)

Question 2

What are the 4 propeller components of airframe torque?

Answer 2

(1) torque from the engine and propeller rotation,
(2) corkscrewing slipstream,
(3) propeller gyroscopic action, and
(4) P-Factor (asymmetric thrust created by prop)

Question 3

The asymmetric thrust and drag changes that accompany engine failure affects a multiengine
aircraft in the following ways:

Answer 3

Pitch Down

Roll into the Failed Engine

Yaw into the Failed Engine

Question 4

Which engine is critical in a twin engine aircraft w/ two clockwise rotating props and which components are responsible?

Answer 4

Left engine

P-Factor, Corkscrewing and Accelerated Slipstream, and Torque Reaction

Question 5

VMCA may not be greater than X times stall speed with flaps in takeoff
position and gear retracted.

Answer 5

1.2

Question 6

VMCA decreases with:

Answer 6

1. Increased gross weight.
2. Reduced power on operating engine.
3. Aircraft has no critical engine (Seminole).
4. Feathered prop on inoperative engine.
5. Center of gravity more forward.
6. Gear extended (gear acts as stabilizing force and reduces yaw/drag).
7. Higher density altitude (temp/PA). Higher DA reduces asymmetric power.
8. Bank up to 5 degrees into the good engine.

Question 7

Loss of an engine results in a

XX percent reduction in power, but an XX percent loss of excess power.

Question 14

Icing may be initially indicated by

Answer 14

Answer 19

the hydraulic system / springs

Question 20

The Seminole is equipped with a gear warning horn that will sound

throttle is set with manifold pressure below 15”

flaps are down 25 or 40 degrees

Question 21

The brakes are activated by

Answer 21

an independent hydraulic system.

Question 22

The flaps are spring loaded to return to the up position and detents are located at flap
extensions of

Answer 22

10, 25 and 40 degrees

Question 23

The Seminole has a XX volt electrical system powered by two XX volt, XX amp engine driven
alternators. A XX volt, XX amp hour battery in the nose provides power when the engines are not
operating or in case of alternator failure.

Answer 23

14, 14, 70, 12, 35

Question 24

The system is protected by overvoltage relays in each alternator that disconnect an errant
alternator from the system when output voltage exceeds

Answer 24

17 volts

Question 25

The airspeed indicator, altimeter and VSI operate with

Answer 25

static and dynamic air pressure from a

heated pitot tube and static port under the left wing

Question 26

the inboard stall detector operates when the

flaps are XX or XX degrees and the outboard detector operates with the flaps less than XX degrees.
