Airplane instruments, Engines, and Systems Flashcards
In the northern hemisphere, a magnetic compass will normally indicate a turn toward the north if
an aircraft is accelerated while on an east or west heading
Deviation in a magnetic compass is caused by the
magnetic within the aircraft distorting the lines of magnetic force
During flight, when are the indications of a magnetic compass accurate
only in straight and level unaccelerated flight
Deviation error of the magnetic compass is caused by
Certain metals and electrical Systems within the aircraft
in the northern hemisphere, if an aircraft is accelerated or decelerated, the magnetic compass will normally indicate
correctly when on a south or north heading
In the Northern hemisphere, the magnetic compass will normally indicate intitnally a turn toward the west if
a right turn is entered from a north heading
In the Northern hemisphere, the magnetic compass will normally indicate a turn towards south when
the aircraft is decelerated while on a west heading
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 right, but at a faster rate than is actually occurring
In the northern hemisphere, a magnetic compass will normally indicate initially a turn east if
a left turn is entered from a north heading
the pitot system provides impact pressure for which instrument
Airspeed indicator
Which instrument will become inoperative if the pitot tube becomes clogged
Airspeed indicator
if the pitot tube and outside static vents become clogged, which instruments would be affected?
The altimeter, airspeed indicator, and vertical speed indicator
Which instrument will become inoperative if the static vents become clogged?
Airspeed indicator, altimeter, and vertical speed indicator
What Nisan important airspeed limitation that is not color coded on airspeed indicators?
Maneuvering speed
What does the red line on an airspeed indicator represent?
Never-exceed speed
What is absolute altitude
The vertical Distance of the aircraft above the surface
What is true altitude?
The vertical distance of the aircraft above sea level
What is density altitude?
The pressure altitude corrected for nonstandard temp.
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 fields elevation
Under what condition is indicated altitude the same as true altitude?
When at sea level under standard conditions
Under what condition is pressure altitude and density altitude the same value
At standard temperature
Under what condition will pressure altitude be equal to true altitude?
When standard atmospheric conditions exist?
If it is necessary to set the altimeter from 29.15 to 29.85, what will change?
700 ft increase in indicated altitude
If a pilot changes the altimeter setting from 30.11 to 29.96, what is the approximate change in indication?
Altimeter will indicate 150 ft lower
If a flight is made from an area of low pressure into an area of high pressure without the altimeter setting be adjusted, the altimeter will indicate
Lower than the actual altitude above sea level
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.
