Ground Operation & Servicing Flashcards
- During starting of a turbine powerplant using a compressed air starter, a hung start occurred. Select the proper procedure.
a. Advance power lever to increase RPM.
b. Re-engage the starter.
c. Shut the engine down.
c.
- A hung start in a jet engine is often caused by
a. malfunctions in the ignition system.
b. the starter cutting off too soon.
c. an excessively rich fuel/air mixture.
b.
- Which statement below reflects a typical requirement when towing some aircraft?
a. Discharge all hydraulic pressure to prevent accidental operation of the nosewheel steering mechanism.
b. Tailwheel aircraft must be towed backwards.
c. If the aircraft has a steerable nosewheel, the torque-link lock should be set to full swivel.
c.
- Which statement(s) is/are true regarding tiedown of small aircraft?
(1) Manila (hemp) rope has a tendency to stretch when it gets wet.
(2) Nylon or dacron rope is preferred to manila rope.
(3) The aircraft should be headed downwind in order to eliminate or minimize wing lift.
(4) Leave the nosewheel or tailwheel unlocked.
a. 1, 2, 3, and 4
b. 1 and 2
c. 2
c.
- When approaching the front of an idling jet engine, the hazard area extends forward of the engine approximately
a. 10 feet
b. 15 feet
c. 25 feet
c.
- Which of the following is the most satisfactory extinguishing agent for use on a carburetor or intake fire?
a. Dry chemical.
b. A fine, water mist.
c. Carbon dioxide.
c.
- If a radial engine has been shut down for more than 30 minutes, the propeller should be rotated through at least two revolutions to
a. check for hydraulic lock.
b. check for leaks.
c. prime the engine.
a.
- The priming of a fuel injected horizontally opposed engine is accomplished by placing the fuel control lever in the
a. IDLE-CUTOFF position.
b. AUTO-RICH position.
c. FULL-RICH position.
c.
- The most important condition to be monitored during start after fuel flow begins in a turbine engine is the
a. EGT, TIT, or ITT.
b. RPM.
c. oil pressure.
a.
- Which of the following conditions has the most potential for causing engine damage when starting or attempting to start a turbine engine?
a. Hung start.
b. Cold start.
c. Hot start.
c.
- How is a flooded engine, equipped with a float-type carburetor, cleared of excessive fuel?
a. 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.
b. Turn off the fuel and the ignition. Discontinue the starting attempt until the excess fuel has cleared.
c. 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.
- Generally, when an induction fire occurs during starting of a reciprocating engine, the first course of action should be to
a. discharge carbon dioxide from a fire extinguisher into the air intake of the engine.
b. continue cranking and start the engine if possible.
c. close the throttle.
b.
- When starting and ground operating an aircraft’s engine, the aircraft should be positioned to head into the wind primarily
a. to aid in achieving and maintaining the proper air flow into the engine induction system.
b. for engine cooling purposes.
c. to help cancel out engine torque effect.
b.
- When approaching the rear of an idling turbojet or turbofan engine, the hazard area extends aft of the engine approximately
a. 200 feet
b. 100 feet
c. 50 feet
b.
- If a hot start occurs during starting of a turbine powerplant, what is the likely cause?
a. The starting unit overheated.
b. The ambient air temperature was too high (over 100 degrees F).
c. The fuel/air mixture was excessively rich.
c.
