Q

Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates

A

true altitude at field elevation.

16
Q

If a pilot changes the altimeter setting from 30.11 to 29.96, what is the approximate change in indication?

A

Altimeter will indicate 150 feet lower.

17
Q

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

A

lower than the actual altitude above sea level.

18
Q

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

A

higher than the actual altitude above sea level.

19
Q

How do variations in the temperature affect the altimeter?

A

Pressure levels are raised on warm days and the indicated altitude is lower than true altitude.

20
Q

Under what condition will true altitude be lower than indicated altitude?

A

In colder than standard air temperature.

21
Q

Which condition would cause the altimeter to indicate a lower altitude than true altitude?

A

Air temperature warmer than standard.

22
Q

What is an advantage of an attitude indicator that is displayed digitally?

A

The horizon line extends all the way to the edges of the PFD.

23
Q

The Air Data Computer or ADC

A

combines data from the pitot-static sensors and temperature sensors.

24
Q

During flight, when are the indications of a magnetic compass accurate?

A

Only in straight-and-level unaccelerated flight.

25
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. (ANDS) Accelerate North Decelerate South
26
In the Northern Hemisphere, the magnetic compass will normally indicate a turn toward the south when
the aircraft is decelerated while on a west heading.
27
In the Northern Hemisphere, if an aircraft is accelerated or decelerated, the magnetic compass will normally indicate
correctly when on a north or south heading.
28
In the Northern hemisphere, a magnetic compass will normally indicate initially a turn toward the west if
a right turn is entered from a north heading. NO (North Opposite)
29
In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the east if
a left turn is entered from a north heading.
30
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, but at a faster rate than is actually occurring.
31
Deviation in a magnetic compass is caused by the
magnetic fields within the aircraft distorting the lines of magnetic force.
32
Deviation error of the magnetic compass is caused by
certain metals and electrical systems within the aircraft.
