Flight Instruments (42 questions) Flashcards
If a flight is made from an area of LOW pressure into an area of HIGH pressure without the altimeter setting being adjusted, the altimeter will indicate
LOWER than the actual altitude above sea level.
High to Low, look out BELOW - altimeter reads high
(Low to high, altimeter reads low…)
What should be the indication on the magnetic compass as you roll into a standard rate turn to the RIGHT from a SOUTH heading in the Northern Hemisphere?
The compass will indicate a turn to the right, bat at a FASTER rate than is actually occurring.
(North is opposite indication, South is accelerated indication)
Under what condition will TRUE altitude be LOWER than INDICATED altitude?
In COLDER than STANDARD air temperature.
True, Lower, Colder (TLC)
PTA (low to high)
Pressure - True (Sea Level) - Absolute (AGL)
How do variations in temperature affect the altimeter?
Pressure levels are RAISED on WARM days and the indicated altitude is LOWER than TRUE altitude.
(INCREASED pressure indicates LOWER altitude)
Deviation in a magnetic compass is caused by the
magnetic fields WITHIN THE AIRCRAFT distorting the lines of magnetic force.
(VARIATION is difference between magnetic and true)
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.
PTA: TRUE = MSL
The proper adjustment to make on the attitude indicator during level flight is to align the
miniature airplane to the horizon bar.
Which V-speed represents MANEUVERING speed?
V (A).
Which condition would cause the altimeter to indicate a LOWER altitude than TRUE altitude?
Air temperature WARMER than STANDARD.
Lower, True, Warmer (LTW: lightweight)
