(199).jpg "Aircraft General Knowledge Quiz! Trivia - Quiz")
Have you ever seen an aircraft? They are pretty cool to look at when they are up in the air. An aircraft can use either static or dynamic lift, or sometimes the downward thrust of jet engines. Some examples of aircraft include airplanes, helicopters, airships, and hot air balloons. Get ready for this quiz with well-researched questions on aircrafts and prepare for take-off. You can do it.

- B.
The most power can be obtained for any given throttle setting
- C.
A given power can be obtained with the highest manifold pressure or throttle setting
- 14.The mixture control can be adjusted, which
- A.
Prevents the fuel/air combination from becoming too rich at higher altitudes
- B.
Regulates the amount of airflow through the carburetor’s venture
- C.
Prevents the fuel/air combination from becoming lean as the airplane climbs
- 15.What effect, if any, would a change in ambient temperature or air density have on gas turbine engine performance?
- A.
As air density decreases, thrust increases
- B.
As temperature increases, thrust increases
- C.
As temperature increases, thrust decreases
- 16.Which statement is true concerning the effect of the application of carburetor heat?
- A.
It enriches the fuel/air mixture
- B.
It leans the fuel/air mixture
- C.
It has no effect on the fuel/air mixture
- 17.Applying carburetor heat will:
- A.
Not affect the mixture
- B.
Lean the fuel/air mixture
- C.
Enrich the fuel/air mixture
- 18.Leaving the carburetor heat on during takeoff.
- A.
Leans the mixture for more power on takeoff
- B.
Will decrease the takeoff distance
- C.
Will increase the ground roll
- 19.Detonation occurs in a reciprocating aircraft engine when:
- A.
There is an explosive increase in fuel caused by too rich a fuel/air mixture
- B.
The spark plugs receive an electrical jolt caused by a short in the wiring
- C.
The unburned fuel/air change in the cylinders is subjected to instantaneous combustion
- 20.Detonation can be caused by:
- A.
A “rich” mixture
- B.
Low engine temperatures
- C.
Using a lower grade of fuel than recommended
- 21.The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as:
- A.
Instantaneous combustion
- B.
Detonation
- C.
Pre-ignition
- 22.Detonation may occur at high-power settings when:
- A.
The fuel mixture ignites instantaneously instead of burning progressively and evenly
- B.
An excessively rich fuel mixture causes an explosive gain in power
- C.
The fuel mixture is ignited too early by hot carbon deposits in the cylinder
- 23.Before shutdown, while at idle, the ignition key is momentarily turned OFF. The engine continues to run with no interruption; this
- A.
Is normal because the engine is usually stopped by moving the mixture to idle cutoff
- B.
