what special precautions should be taken when towing an aircraft that is equipped with a steerable nose wheel |
be sure that the nose wheel does not try to turn past its stops. some aircraft must have the torsion links on the nose wheel strut dissconected when they are being towed
|
|
|
what publication lists the standard hand signals that are used for directing a taxing aircraft |
ASA AMT–G page 629
|
|
|
what action should a mechanic take while taxiing an aircraft on a runway if the tower shines a flashing red light at him
|
take the aircraft clear of the taxiway in use
|
|
|
what type of fire extinguisher is best suited for extinguishing an induction fire on a reciprocating engine
|
carbon dioxide
|
|
|
what is the proper way to extinguish an induction system fire that occurs when starting a reciprocating engine
|
keep the engine running and blow the fire out, if this does not work use a CO2 fire extinguisher directed into the carburetor inlet
|
|
|
when starting an aircraft engine that is equipped with a float carburetor, in what position should the carb heat control be placed
|
in the full cold position
|
|
|
what is meant by a liquid lock in the cylinder of an aircraft engine, and how is one cleared
|
oil accumulates in the cylinders below the center line of the engine and prevents the piston moving to the top of its stroke. To clear a liquid lock, remove one of the spark plugs and turn the crankshaft until all of the oil is forced out of the cylinder
|
|
|
what must be done if a hung start occurs when starting a turbojet engine
|
terminate the starting operation and find the reason the engine would not accelerate as it should
|
|
|
how far ahead of an idling turbojet does the danger area extend |
25 feet
|
|
|
Why is it important that the aircraft and the fuel truck be grounded together before the aircraft is fueled?
|
grounding prevents the buildup of static electricity that causes sparks that could ignite the fuel vapors
|
|
|
what information must be located near the fuel tank filler opening in the aircraft powered by a reciprocating engine
|
the word AVGAS" and the minimum fuel grade"
|
|
|
what information must be located near the fuel tank filler opening of an aircraft powered by a turbine engine
|
the words JET FUEL", permissible fuel designations, or references to the airplane flight manual"
|
|
|
what should be done to a reciprocating engine fuel system if turbine fuel is inadvertently put into the tanks and the engine is run |
the entire fuel system must be drained and flushed with gasoline, the engine given a compression check and all of the cylinders given a borescope inspection. the oil must be drained and all of the filters and strainers checked. after the aircraft is properly fueled, the engine must be given a proper run up and check
|
|
|
What precaution must be observed regarding the tools used when servicing an aircraft oxygen system?
|
be sure that there is no oil or grease on the tools. Pure oxygen can cause spontaneous combustion of petroleum products
|
|
|
What kind of rope is best to tie down an aircraft?
|
nylon or polypropylene
|
|
|
What kind of knot is used for securing an airplane with a rope?
|
bowline
|
|
|
why is it important that turbine fuel not to be mixed with aviation gasoline that is used in an aircraft reciprocating engine
|
the turbine engine fuel will cause the engine to detonate
|
|
|
what grade of aviation gasoline is dyed blue
|
low lead 100–octane
|
|
|
what damage is likely to occur if an aircraft reciprocating engine that is designed to use 100– octane fuel is operated with 80–octane fuel
|
detonation will occur, which will cause such things as bent rods, burned pistons and cracked cylinder heads
|
|
|
what is meant by detonation in an aircraft reciprocating engine
|
detonation is an uncontrolled burning of fuel in the cylinder of the engine. its an explosion rather than a smooth burning
|
|
|
what is the danger of using a fuel that that vaporizes too readily
|
vapor lock can occur in the fuel lines. this will shut off fuel flow to the engine
|
|
|
what type of jet fuel is A fuel |
a fuel with a heavy kerosine base , a flash point of 110–150 F and a freezing point of –40 F, and a heat energy content of 18,600 BTU/pound
|
|
|
what are the two functions of tetraethyl lead that is added to aviation gasoline |
it increases the critical pressure and temperature of the fuel, and it acts as a lubricant for the valves
|
|
|
What documentaion is required for a certificated aircraft to legally operate on automotive gasoline? |
theere must be a supplemental type certificate for the aircraft to operate on automotive gasoline |
