37
What precautions must you take to stay safe on the flight line?
Use hearing protection, be aware of | the danger of FoD.
38
What should you do in extreme wind conditions when tying down a plane?
You must try and break up the smooth airflow over the wings, this can be done by using batten boards, facing the aircraft into the wind, and depending on the aircraft, angling the elevators.
39
What are two turbine start problems?
Hot start | Hung start
40
What is a hot start?
Too much fuel for airflow, over temperature of turbine.
41
What is a hung start?
It is when the starter disengages too early, and the compressor does not accelerate enough to start.
42
What is proper procedure for taxiing?
Be sure you are qualified and know proper procedures. Be sure the area is clear. In close proximity of a building, or other aircraft, use a signal man. The signal man should ensure he can see the pilot's eyes. Know hand signals. In a controlled airport, you must have clearance from ground control. If no radio is available, you must use light signals.
43
Turbine engines.....?
Power Crank Ignition Fuel
44
What do you do in case of an induction fire upon engine start?
- mixture- lean or idle cutoff - throttle- full open - continue cranking.
45
One the engine starts look immediately for _________.
Oil pressure
46
Where should you never do a run up?
On gravel or loose dirt.
47
What two fueling procedures are there?
Over the wing Single point
48
What is a disadvantage associated with single point fueling?
It is easy to over pressurize the tanks.
49
What is an advantage of single point fueling?
It is quicker, and there is less chance of contamination.
50
What kind of aircraft use single point fueling?
Larger aircraft.
51
How can you tell if there is a high level of surfactants in fuel?
There will be a brown sudsy substance in the fuel.
52
What causes surfactants?
Surfectants are a normal byproduct of the refining process, but excess levels can cause problems for the filters as well as burn problems for the fuel.
53
What is misfueling?
Misfueling can either be fueling with the wrong type of fuel, or the wrong grade or designation.
