Answer 2

Increase the RPM before increasing the manifold pressure.

Question 3

How should you establish climb power after takeoff in an airplane equipped with a constant-speed propeller ?

Answer 3

first decrease manifold pressure and then decrease RPM.

Question 4

Propeller efficiency is the

Answer 4

ratio of thrust horsepower to brake horsepower.

Question 5

To develop maximum power and thrust, a constant-speed propeller should be set to a blade angle that will produce what ?

Answer 5

small angle of attack and high RPM.

Question 6

A detuning of engine crankshaft counterweights is a source of overstress that may be caused by

Answer 6

rapid opening and closing of the throttle.

Question 7

What is positive limit load factor ?

Answer 7

the greatest positive load that may be placed on the aircraft without risk of structural damage.

Question 8

How should the blade angle of a controllable-pitch propeller should be set at takeoff ?

Answer 8

small angle of attack and high RPM.

Question 9

Maximum structural cruising speed is the maximum speed at which an airplane can be operated during

Answer 9

Normal Operations (Vno)

Question 10

A fixed-pitch propeller is designed for best efficiency only at a given combination of

Answer 10

airspeed and RPM.

Question 11

True airspeed is best described as calibrated airspeed corrected for

Answer 11

altitude and nonstandard temperature.

Question 12

Structural damage or failure is more likely to occur in smooth air at speeds above what speed ?

Answer 12

Vne

Question 13

To establish a climb after takeoff in an aircraft equipped with a constant-speed propeller, the output of the engine is reduced to climb power by decreasing manifold pressure and

Answer 13

decreasing RPM by increasing propeller blade angle.

Question 14

What is an operational difference between the turn coordinator and the turn-and-slip indicator? The turn coordinator

Answer 14

Indicates roll rate, rate of turn, and coordination; the turn-and-slip indicator indicates rate of turn and coordination. (ie. both provide rate-of-turn and coordination)

Question 15

When referring to a constant speed propeller, the pitch setting is

Answer 15

varied in flight by a governor maintaining constant RPM despite varying air loads.

Question 16

Which statement best describes the operating principle of a constant-speed propeller?

Answer 16

The propeller control regulates the engine RPM and in turn the propeller RPM.

Question 17

A propeller rotating clockwise as seen from the rear, creates a spiraling slipstream. The spiraling slipstream, along with torque effect, tends to rotate the airplane to the

Answer 17

left around the vertical axis, and to the left around the longitudinal axis.

Question 18

In aircraft equipped with constant-speed propellers and normally-aspirated engines, which procedure should be used to avoid placing undue stress on the engine components? When power is being…

Answer 18

increased, increase the RPM before increasing the manifold pressure.

Question 19

Which statement best describes the operating principle of a constant-speed propeller?

Answer 19

The propeller control regulates the engine RPM and in turn the propeller RPM.

Question 20

What should you avoid that places undue stress on an engine equipped with a constant-speed propeller ?

Answer 20

low RPM and high-manifold pressure.

Question 21

The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as

Answer 21

preignition.

The horizontal dashed line from point C to point E represents the

Answer 25

postive limit load factor

Question 26

Detonation occurs in a reciprocating aircraft engine when

Answer 26

the unburned fuel/air charge in the cylinders is subjected to instantaneous combustion.

Question 27

The best power mixture is that fuel/air ratio at which

Answer 27

the most power can be obtained for any given throttle setting.
