Aircraft Systems Flashcards
To properly purge water from the fuel system of an aircraft equipped with fuel tank sumps and a fuel strainer quick drain, it is necessary to drain the fuel from the…?
Fuel strainer drain and the fuel tank sumps
In what flight condition are torque effects more pronounced in a single-engine airplane?
Low airspeeds, high power, high angle of attack
Applying carburetor heat will…?
Enrich the fuel/air mixture
The possibility of carburetor icing exits even when the ambient air temperature is as…?
High as 70F and the relative humidity is high
The operating principle of float-type carburetors is based on the…?
Difference in the air pressure at the Venturi throat and the air inlet
What type fuel can be substituted for an aircraft if the recommended octane is not available
The next higher octane aviation gas
The left turning tendency of an airplane caused by P-factor is the result of the…?
Propeller blade defending in the right, producing more thrust than the ascending blade on the left
The most important rule to remember in the event of power failure after becoming airborne is to…?
Immediately establish the proper gliding attitude and airspeed
If an aircraft is equipped with a fixed-pitch propeller and an float-type carburetor, the first indication of carburetor ice would mostly be…?
Loss of RPM
Filling the fuel tanks after the last flight of the day is considered a good operating procedure because this will…?
Prevent moisture condensation by eliminating airspace in the tanks.
If the engine oil temperature and cylinder head temp gauge have exceed their normal operating range, the pilot may have been operating with…?
Too much power and with the mixture set too lean
What is the purpose for using reciprocating engines?
They are relatively simple and inexpensive to operate
Carburetor icing can occur with an OAT as high as…?
20C and high relative humidity
If the ground wire between the magneto and the ignition switch becomes disconnected, the most noticeable result will be that the engine…?
Cannot be shut down by turning the switch to the OFF position
Which would most likely cause the cylinder head temp and engine oil temp gauges to exceed their normal operating ranges?
Using a fuel that has a lower-than-specified fuel rating
The uncontrollable firing of the fuel/air charge in advance of normal spark ignition is known as…?
Pre-ignition
Detonation may occur at high-power settings when…?
The fuel mixture ignites instantaneously instead of burning progressively and evenly
Which condition is most favorable to the development of carburetor icing?
Temp between 20 and 70F and high humidity
How should an aircraft preflight inspection be accomplished for the first flight of the day?
Thorough and systematic means recommend by the manufacturer
How is the engine operation controlled on an engine equipped with a constant-speed propeller?
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…?
Improved engine performance
Generally speaking, the use of carburetor heat tends to…?
Decrease engine performance.
An electrical system failure (battery and alternator) occurs during flight. In the situation, you would…?
Experience avionics equipment failure
