Aviation Flashcards
The pitot system provides impact pressure for which instrument?
Airspeed indicator
Which instrument(s) will become inoperative if the static vents become clogged?
Airspeed, altimeter, and vertical speed
Which instrument will become inoperative if the pitot tube becomes
clogged?
Airspeed
What does the red line on an airspeed indicator represent?
Never-exceed speed
What is an important airspeed limitation that is not color coded on
airspeed indicators?
Maneuvering speed
If a pilot changes the altimeter setting from 30.11 to 29.96, what is the approximate change in indication?
Altimeter will indicate 150 feet lower
How do variations in temperature affect the altimeter?
Pressure levels are raised on warm days and the indicated altitude is lower than true altitude.
If it is necessary to set the altimeter from 29.15 to 29.85, what change Occurs?
700-foot increase in indicated altitude
What is true altitude?
The vertical distance of the aircraft above sea level
What is absolute altitude?
The vertical distance of the aircraft above the surface
What is density altitude?
The pressure altitude corrected for nonstandard temperature
What is pressure altitude?
The altitude indicated when the barometric pressure scale is set to
29.92
Altimeter setting is the value to which the barometric pressure scale of
the altimeter is set so the altimeter indicates
true altitude at field elevation
Under which condition will pressure altitude be equal to true altitude?
When standard atmospheric conditions exist
If a flight is made from an area of high pressure into an area of lower pressure without the altimeter setting being adjusted, the altimeter will indicate
higher than the actual altitude above sea level
