Engine Flashcards
Which would most likely cause the cylinder head temperature and engine oil temperature gauges to exceed their normal operating ranges?
- Using fuel that has a lower than specified fuel rating.
Why might detonation occur at high power settings?
- When the fuel mixture ignites instantaneously instead of burning progressively.
What change occurs in the fuel/ air mixture when carburetor heat is applied?
- The fuel/ air mixture becomes richer
A positive indication on an ammeter shows what?
- Shows the rate of charge for the battery.
On aircraft’s, equipped with fuel pumps, when is the auxiliary fuel pump used?
- In the event the engine driven fuel pump fails.
Why is filling the fuel tanks after the last flight of the day considered a good thing?
- It helps prevent moisture by eliminating airspace in the tanks.
What is pre-ignition?
- The uncontrolled firing ahead of the normal spark ignition?
While cruising at 9,500 MSL, the fuel/ air mixture is properly adjusted. What will happen if a descent to 4,500 MSL is made without readjusting the mixture?
- The fuel/ air mixture may become excessively lean.
What is one procedure to aid in cooling an engine that is overheating?
- Enrichen the mixture
What action can a pilot take to aid in cooling an engine that is overheating during a climb?
- Reduce rate of climb
- Increase airspeed
An abnormally high engine oil temperature indication may be caused by……
- The oil level being too low
If the engine oil temperature and cylinder head temperature gauges have exceeded their normal operating range. What might be pilot have been operating with?
- too much power with mixture set too lean
If the grade of fuel used in an aircraft engine is lower than specified for the engine, it will most likely cause…..
- Detonation
To keep a battery charged the, the alternator voltage output should be….
- Higher than the battery voltage.
