Stage 1 practice test Flashcards
What causes an airplane (except a T-tail) to pitch nosedown when power is reduced and controls are not adjusted?
the downwash on the elevator from the propeller slipstream is reduced and elevator effectiveness is reduced.
What force makes an airplane turn?
The horizontal component of lift.
The amount of excess load that can be imposed on the wing of an airplane depends upon the
speed
In what flight condition must an aircraft be placed in order to spin?
stalled
Loading an airplane to the most aft CG will cause the airplane to be
less stable at all speeds.
During an approach to a stall, an increased load factor will cause the airplane to
stall at a higher airspeed.
The uncontrolled firing of the fuel/air charge in advance of normal spark ignition is known as
pre-ignition.
The presence of carburetor ice in an aircraft equipped with a fixed-pitch propeller can be verified by applying carburetor heat and noting
a decrease in RPM and then a gradual increase in RPM.
The operating principle of float-type carburetors is based on the
difference in air pressure at the venturi throat and the air inlet.
If an aircraft is equipped with a fixed-pitch propeller and a float-type carburetor, the first indication of carburetor ice would most likely be
loss of RPM.
What is true altitude?
The vertical distance of the aircraft above sea level.
The pitot system provides impact pressure for which instrument?
Airspeed indicator.
What is pressure altitude?
The altitude indicated when the barometric pressure scale is set to 29.92.
