Ground Handling And Servicing

Question 1

What is the most generally used knot for tying an aircraft down

Answer 1

Bowline

Question 2

Describe precautions that should be taken to protect life and property while starting and running an aircraft engine.

Answer 2

Study the procedure in Airplane Flight Manuel. Make sure propeller or inlet are is clear of debree Also make sure prop or jet blast doesn’t blow into the hangers or other airplanes and have a fire guard

Question 3

If an engine induction fire occurs while starting a reciprocating engine, what procedure should be followed to extinguish the fire?

Answer 3

Continue cranking the engine to start it and blow out the fire. If the engine does not start then use CO2

Question 4

What procedure should be followed prier to starting a large radial engines to detect or prevent hydraulic lock in the cylinder?

Answer 4

Pull propeller by hand for three or four complete turns. Resistance to the prop turning indicates a possible hydraulic lock

Question 5

What is the cause of hydraulic lock in large radial engine ?

Answer 5

Oil seeps by the piston rings and accumulates in the combustion chamber of lower cylinders. When a piston comes up on its compression stroke the incompressible liquid seizes it.

Question 6

What is meant by the term “hot start” when starting a jet engine?

Answer 6

an excessively rich mixture at starting leading to fast temperature rise that can exceed the EGT limits

Question 7

When towing an aircraft , should you use the tow vehicle or aircraft brakes to stop the aircraft?

Answer 7

The tow vehicle brakes should be used except for emergency then the aircrafts brakes may be used

Question 8

Why should an aircraft technician be familiar with slandered light signals

Answer 8

Light signals may be used when taxiing an airplane without radio or when radio is not working

Question 9

If a mixture of aviation gasoline and jet fuel is used in a reciprocating aircraft engine what are the possible results

Answer 9

engine may be damaged or destroyed

Question 10

What does the number 100 signify in 100LL aviation gasoline

Answer 10

It’s the lean mixture performance number of the fuel

Question 11

Is it permissible to use AVGAS in a turbine engine

Answer 11

it reduced efficiency due to lead deposits on the turbine blades so limited use is given by manufacture

Question 12

What are some of the possible outcomes of using a lower grade of AVGAS than the specified grade?

Answer 12

chance of engine damage due to detonation,

loss of engine power and an increased chance of overheating

Question 13

Part 23.973 of the FAA regulations specifies that certain makings must be placed adjacent to fuel filler openings. What markings are used for reciprocating engine powered airplanes?

Answer 13

Must be marked with fuel grade and the word “AVGAS”

Question 14

Describe the important precautions that should be observed when fueling an aircraft

Answer 14

Be certain you are using the correct fuel properly ground the aircraft and refueling unit and protect the aircraft surfaces from hose and nozzle damage

Question 15

The marking requirements for oil tank filler openings are specified by FAR 23.1157. What markings are required for piston engine powered airplane?

Answer 15

The word OIL and the permissible grades and types or a reference place

Question 16

Where can the standard aircraft taxi hand signal be found

Answer 16

Airman’s information Manual

Question 17

Under what condition should a reciprocating engine be pre oiled

Answer 17

Prior to starting a new engine or one that has been preserved for storage ensures it’s lubricated properly

Question 18

Under what condition may automobile gasoline be used in an aircraft engine

Answer 18

Only if approved by FAA usually by the issuance of a Supplemental Type Certificate

Question 19

What are the indication of water in aircraft fuel after draining a sample from the fuel sumps

Answer 19

The sample may have a cloudy or hazy appearance or a solid slug of water

Question 20

Name at least 3 possible hazards that may be encountered during typical ground operations such as during engine run-up or taxiing?

Answer 20

Possible fire during engine start, other vehicles, and high noise levels that may cause hearing damage

Question 21

What damage is likely to occur when force is exerted on the crankshaft when there is liquid lock

Answer 21

A bent or broke connecting rod

Question 22

What information must be located either on or rear the fuel filling openings or oil filling openings

Answer 22

The word FUEL and the minimum fuel grade and the word OIL
