Aircraft Ground Operations and Safety Flashcards
-SJVC Aviation -AERO-30
What must be done when fueling an aircraft to prevent a charge of static electricity causing a spark which may result in a fire?
Ground the aircraft
What is the color of 100LL fuel?
Blue
What is the most likely effect of using 80-octane fuel in an engine designated for 100-octane?
Detonation
A fuel which vaporizes to slow may cause what problem, if any?
Hard Starting
Why is ethylene dibromide added to aviation gasoline?
To dissipate lead oxide from the combustion chamber
What are the characteristics of a reciprocating engine that is experiencing detonation?
Rapid rise in cylinder pressure, excessive cylinder head temperature, and a decrease in engine power
Why should a pilot of a small aircraft visually check the fuel in the fuel tanks during the preflight?
To compare the fuel level with the fuel quantity gage(s)
(1) Jet fuel is of a higher viscosity than aviation gasoline and therefore holds contaminants better
(2) Viscosity has a direct relationship to contamination of fuel
Which is/are true?
Both number one and two are true
What is the chief advantage kerosene has over gasoline?
Kerosene has a higher heat energy per unit volume than gasoline
What is the best extinguishing agent for use on a carburetor/intake fire or an engine fire?
Halon
When starting a piston engine equipped with a float-type carburetor, the carburetor heat control should be place in which position?
Cold position
Which instrument should be checked immediately after a successful start of a reciprocating engine?
Oil pressure
The starting of a fuel-injected horizontally opposed engine begins by placing the fuel control lever in which position?
Idle-cutoff position
Which instrument is the most important to monitor during the starting operation of a turbine engine?
EGT
What is the most likely cause of having a hot start in attempting to start a turbine engine?
Too rich a fuel/air mixture
While attempting to start a turbine engine aircraft you experience a hung start, what procedure should be followed?
Shut the engine down immediately
Identify the signal to engage rotor on a helicopter.
One hand pointed up with the other pointed up doing a circular motion
Identify the signal which should be given to a pilot if his aircraft is in imminent danger of striking an object.
Extend both up arms waving them across each other
How do you steer a small aircraft on the ground?
Rudder pedals
What color are taxiway lines?
Yellow
What should you do when taxi an aircraft and you approach two solid lines followed by two broken lines?
Stop before you cross the lines, unless you have permission to cross from the tower.
What does a red square with a white circle with a white diagonal line on it designate?
Shows where you should not taxi the aircraft.
What does a yellow sign with a left arrow and the letter “B” on it designate
Gives you directions to runway, taxiway, or other airport destination.
What does the flashing lights mean right before two broken lines and two solid lines?
Indicates you are approaching a runway.
