Content:
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 Taxiing (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 taxiing (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 and 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.
How are aviation fuels, which possess greater antiknock qualities than 100 octame, classified? According to the milliliters of lead. By reference to normal heptane. By performance numbers.
Weathervaning tendency is greater when taxiing both nosewheel and tailwheel-type airplanes in a quartering tailwind a tailwheel-type airplane in a direct crosswind. a nosewheel-type airplane in a quartering headwind.
Tetraethyl lead is added to aviation gasoline to retard the formation of corrosives improve the gasoline`s performance in the engine dissolve the moisture in the gasoline.
The priming of a fuel injected horizontally opposed engine is accomplished by placing the fuel control lever in the IDLE-CUTOFF position AUTO-RICH position FULL-RICH position.
Which of the following is the most satisfactory extinguishing agent for use on a carburator intake fire? Dry chemical A fine water mist Carbon dioxide.
During starting of a turbine powerplant using a compresed air, starter, a hung start occures. Select the proper procedure: Shut off the fuel Re-engage the starter Shut the engine down.
When taxiing (ot towing) an aircraft, an alternating red and green light from the control tower means move clear of the runway/taxiway immediately OK to proceed but use extreme caution return to starting point.
If a hot start occurs during starting of a turbine powerplant, what is the likely cause? The starting unit iverheated The ambient air temperature was too high (over 100° F) The fuel/air mixture was excessively rich.
Which of the following conditions has the most potential for causing engine damage when starting or attempting to start a turbine engine? Hung start Cold start Hot start.
When starting and ground operating an aircraft's engine, the aircraft should be positioned to head into the wind primarily to aid achieving and maintaining the proper air flow into the engine induction sistem for engine cooling purposes to help cancel out engine torque effect.
Both gasoline and kerosene have certain advantages for use as turbine fuel. Which statement is true in reference to the advantages of each? Kerosene has higher heat energy/value por unit weight than gasoline Gasoline has higher heat energy/value por unit volume than kerosene Kerosene has higher heat energy/value por unit volume than gasoline.
When approaching the front of an idling jet engine, the harzard area extends forward of the engine approximately: 10 feet 15 feet 25 feet.
Jet fuel number identifiers are performance numbers to designate the volatility of the fuel performance numbers and are relative to the fuel's performance in the aircraft engine type numbers and have no relation to the fuel's performance in the aircraft engine.
Characteristics of detonation are cylinder pressure remains the same, excessive cylinder head temperature, and a decrease in engine power rapid rise in cylinder pressure, excesive cylinder head temperature, and a decrease in engine power rapid rise in cylinder pressure, cylinder head temperature normal, and a decrease in engine power.
When approaching the rear of an idling turbojet or turbofan engine, the harzard area extends aft engine approximately: 200 feet 100 feet 50 feet.
When stopping a nosewheel-type airplane after taxxing (or towing), the nosewheel should be left unlocked and pointed straight ahead turned at a small angle towards uphill if the parking area is not perfectly flat pointed straight ahead.
Which statement below reflects a typical requirement when towing some aircraft? Discharge all hydraulic pressure to prevent accidental operation of the nosewheel steering mechanism Tailwheel aircraft must be toward backwards If the aircraft has a steerable nosewheel, the torque-link lock should be set to full swivel.
A fuel that does not vaporize readily enough can cause vapor lock detonation hard starting.
The most important condition to be monitored during start after fuel flow begins in a turbine engine is the EGT, TIT or ITT RPM oil pressure.
