Answer 1

Fuel strainer drain and the fuel tank sumps

Question 2

In what flight condition are torque effects more pronounced in a single-engine airplane?

Answer 2

Low airspeeds, high power, high angle of attack

Question 3

Applying carburetor heat will…?

Answer 3

Enrich the fuel/air mixture

Question 4

The possibility of carburetor icing exits even when the ambient air temperature is as…?

Answer 4

High as 70F and the relative humidity is high

Question 5

The operating principle of float-type carburetors is based on the…?

Answer 5

Difference in the air pressure at the Venturi throat and the air inlet

Question 6

What type fuel can be substituted for an aircraft if the recommended octane is not available

Answer 6

The next higher octane aviation gas

Question 7

The left turning tendency of an airplane caused by P-factor is the result of the…?

Answer 7

Propeller blade defending in the right, producing more thrust than the ascending blade on the left

Question 8

The most important rule to remember in the event of power failure after becoming airborne is to…?

Answer 8

Immediately establish the proper gliding attitude and airspeed

Question 9

If an aircraft is equipped with a fixed-pitch propeller and an float-type carburetor, the first indication of carburetor ice would mostly be…?

Answer 9

Loss of RPM

Question 10

Filling the fuel tanks after the last flight of the day is considered a good operating procedure because this will…?

Answer 10

Prevent moisture condensation by eliminating airspace in the tanks.

Question 11

If the engine oil temperature and cylinder head temp gauge have exceed their normal operating range, the pilot may have been operating with…?

Answer 11

Too much power and with the mixture set too lean

Question 12

What is the purpose for using reciprocating engines?

Answer 12

They are relatively simple and inexpensive to operate

Question 13

Carburetor icing can occur with an OAT as high as…?

Answer 13

20C and high relative humidity

Question 14

If the ground wire between the magneto and the ignition switch becomes disconnected, the most noticeable result will be that the engine…?

Answer 14

Cannot be shut down by turning the switch to the OFF position

Question 15

Which would most likely cause the cylinder head temp and engine oil temp gauges to exceed their normal operating ranges?

Answer 15

Using a fuel that has a lower-than-specified fuel rating

Question 16

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

Answer 16

Pre-ignition

Question 17

Detonation may occur at high-power settings when…?

Answer 17

Question 19

How should an aircraft preflight inspection be accomplished for the first flight of the day?

Answer 19

Thorough and systematic means recommend by the manufacturer

Question 20

How is the engine operation controlled on an engine equipped with a constant-speed propeller?

Answer 20

The throttle controls power output as registered on the manifold pressure gauge and the prop control regulates engine RPM

One purpose of the dual ignition system on an aircraft engine is to provide for…?

Answer 21

Improved engine performance

Question 22

Generally speaking, the use of carburetor heat tends to…?
