A hung start in a jet is often caused by: malfunctions in the ignition system the starter cutting off too soon an excessively rich furl/air mixture.
When towing a large aircraft: a person should be in the cockpit to watch for obstructions persons should be stationed at the nose, each wingtip, and the empennage at all times a person should be in the cockpit to operate the brakes.
If a radial engine has been shut down for more than 30 minutes, the propeller should be rotated through at least two revolutions to: check for hydraulic lock check for leaks prime the engine.
When first starting to move an aircraft while taxing, it is important to: test the brakes closely monitor the instruments notify the control tower.
When Taxing (or towing) an aircraft, a flashing red light from the control tower means: stop and wait for a green light move clear of the runway/taxiway immediately return to starting point.
What effect, if any, will aviation gasoline mixed with jet fuel have on a turbine engine? No appreciable effect The tetraethyl lead in the gasoline forms deposits on the turbine blades The tetraethyl lead in the gasoline forms deposits on the compressor blades.
When taxing (or towing) and aircraft, a flashing white light from the control tower means: move clear of the runway/taxiway immediately OK to proceed but use extreme caution return to starting point.
Which statement is true regarding tiedown of small aircraft? The aircraft should be headed downwind in order to eliminate or minimize wing lift Leave the nosewheel or tailwheel unlocked Nylon or dacron rope is preferred to manila rope.
When taxing an airplane with a quartering tailwind, the elevators and upwind aileron should be held in the up position upwind aileron should be held in the down position both ailerons should be kept in the neutral position.
Why is ethylene dibromide added to aviation gasoline? To remove zinc silicate deposits from the spark plugs To scavenge lead oxide from the cylinder combustion chambers To increase the antiknock rating of the fuel.
(1) Jet fuel is of higher viscosity than aviation gasoline and therefore holds contaminants better.
(2) Viscosity has no relation to contamination of fuel.
Regarding the above statement only 1 is true both 1 abd 2 are true neither 1 nor 2 is true.
The main differences between grades 100 and 100LL fuel are volatility and lead content volatility, lead content, and color lead content and color.
What must accompany fuel vaporization? An absorption of heat A decrease in vapor pressure A reduction in volume.
Generally, when an induction fire occurs during starting of a reciprocating engine, the first course of action should be to: discharge carbon dioxide from a fire extinguisher into the air intake of the engine continue cranking and start the engine if possible close the throttle.
If a fire develops in an engine during the starting procedure, you should discontinue the start attempt and allow the fireguard to extinguish the fire continue cranking to start the engine and extinguish the fire continue cranking and allow the fireguard to extinguish the fire .
Characteristics of aviation gasoline are high heat value, high volatility high heat value, low volatility low heat value, low volatility.
A Fuel that vaporizes too readily may cause: hard starting detonation vapor lock.
How is a flooded engine, equipped with a float-type carburetor, cleared of excessive fuel? crank the engine with the starter or by hand, with the mixture control in cutoff, ignition switch off, and the throttle fully open, until the fuel charge has been cleared. Turn off the fuel and the ignition. Discontinue the starting attempt until the excess fuel has cleared. crank the engine with the starter or by hand, with the mixture control in cutoff, ignition switch on, and the throttle fully open, until the excess fuel has cleared or until the engine starts.
A person should approach or leave a helicopter in the pilot's field of vision whenever the engine is running in order to avoid the tail rotor the main rotor blowing dust or debris caused by rotor downwash.
The color of 100LL fuel is blue colorless or straw red.
