General Multi Knowledge

Question 1

What is Vmc

Answer 1

Calibrated airspeed at which, when the critical engine is suddenly made inoperative, it is possible to maintain control of the airplane with the engine still inop and maintain straight flight with an angle of bank not more than 5 degrees

Question 2

What is P-Factor

Answer 2

• The downward descending blade takes a larger “bite” out of the air, creating more thrust
• This creates YAW

Question 3

What is Accelerated Slip Stream

Answer 3

• The increased airflow creates more lift, the more lift creates a roll. The more thrust creates the Yaw
• Creates Roll & Pitch

Question 4

What is Spiraling Slipstream

Answer 4

• Using Bernoulli’s Principal, the low pressure made on the faster moving air mixes with the higher pressure air from the slower moving air. This creates the “corkscrew” effect that hits the vertical stabilizer
• Creates Yaw

Question 5

What is Torque

Answer 5

• Newton’s 3rd law, opposite and equal reaction. Engine spinning to the left, will make the plane want to roll right, and vice versa
• Creates Roll

Question 6

What is the Critical Engine

Answer 6

• The engine, if failed, will have the most adverse effect on direction control.
• Why? This is due to PAST

Question 7

Accelerate-Stop Distance

Answer 7

The distance travelled that when reach Vr, losing an engine, and coming to a complete stop

Question 8

Accelerate-Go Distance

Answer 8

The distance required to accelerate to rotation speed, and assuming an engine failure at rotation, climb to 35’ above the
departure end.

Question 9

Service Ceiling

Answer 9

The density altitude which will produce a 100 foot per minute climb when flying in a clean configuration, at the best rate of
climb airspeed with both engines at maximum continuous power.

Question 10

Single-Engine Service Ceiling

Answer 10

The altitude that a twin engine airplane can no longer climb at a rate greater than 50 fpm with one
engine inoperative.

Question 11

Absolute Ceiling

Answer 11

The altitude at which a climb is no longer possible.

Question 12

Single-Engine Absolute Ceiling

Answer 12

The altitude that a twin engine airplane can no longer climb with one engine inoperative.

Also known as Drift Down Altitude

Question 13

Critical Altitude

Answer 13

The maximum altitude under standard atmospheric conditions at which a turbocharged engine can produce its rated horsepower.
Above this altitude, the engine‘s performance will begin to decrease.

Question 14

Conventional Twin

Answer 14

A twin-engine aircraft that has both propellers rotating in the same direction (usually clockwise as viewed from the cockpit)

Question 15

What are the Drag Factors for the Seneca II

Answer 15

• Flaps 25: -240fpm
• Flaps 40: -275fpm
• Windmilling Prop: -200fpm
• Gear Extended: -250fpm
