Private Pilot Study Unit 2: Airplane Instruments, Engines,
and Systems UPDATED ACTUAL Questions and
CORRECT Answers
In the Northern Hemisphere, a magnetic compass will C
normally indicate a turn toward the north if:
a. An aircraft is decelerated while on an east or west
heading.
b. A left turn is entered from a west heading.
c. An aircraft is accelerated while on an east or west
heading.
During flight, when are the indications of a magnetic A
compass accurate?
a. Only in straight-and-level unaccelerated flight.
b. As long as the airspeed is constant.
c. During turns if the bank does not exceed 18*.
Deviation in a magnetic compass is caused by the: C
a. Presence of flaws in the permanent magnets of the
compass.
b. Difference in the location between true north and
magnetic north.
c. Magnetic fields within the aircraft distorting the lines
of magnetic force.
Deviation in a magnetic compass is caused by the: B
a. Northerly turning error.
b. Certain metals and electrical systems within the
aircraft.
c. The difference in location of true north and magnetic
north.
, In the Northern Hemisphere, if an aircraft is accelerated B
or decelerated, the magnetic compass will normally
indicate:
a. A turn momentarily.
b. Correctly when on a north or south heading.
c. A turn toward the south.
In the Northern Hemisphere, a magnetic compass will B
normally indicate initially a turn toward the west if:
a. A left turn is entered from a north heading.
b. A right turn is entered from a north heading.
c. An aircraft is accelerated while on a north heading.
In the Northern Hemisphere, the magnetic compass will C
normally indicate a turn toward the south when:
a. A left turn is entered from an east heading.
b. A right turn is entered from a west heading.
c. The aircraft is decelerated while on a west heading.
In the Northern Hemisphere, a magnetic compass will C
normally indicate initially a turn toward the east if:

What should be the indication on the magnetic B
compass as you roll into a standard rate turn to the
right from a south heading in the Northern
Hemisphere?
a. The compass will initially indicate a turn to the left.
b. The compass will indicate a turn to the right, but at a
faster rate than is actually occurring.
c. The compass will remain on south for a short time,
then gradually catch up to the magnetic heading of the
airplane.
The pitot system provides impact pressure for which C
instrument?
a. Altimeter
b. Vertical-speed indicator
c. Airspeed indicator
Which instrument will become inoperative if the pitot C
tube becomes clogged?
a. Altimeter
b. Vertical speed
c. Airspeed
If the pitot tube and outside static vents become B
clogged, which instruments would be affected?
a. The altimeter, airspeed indicator, and turn-and-slip
indicator.
b. The altimeter, airspeed indicator, and vertical speed
indicator.
c. The altimeter, atitude indicator, and turn-and-slip
indicator
