the difference in location of true north and magnetic north.
Magnetic disturbances from magnetic fields produced by metals and electrical accessories in an aircraft disturb the compass card and
produce an additional error which is referred to as deviation.
IncorrectQuestion 2
0 / 4 pts
Higher temperatures expand the pressure levels and the indicated altitude is higher than true altitude.
Lower temperatures lower the pressure levels and the indicated altitude is lower than true altitude.
Pressure levels are raised on warm days and the indicated altitude is lower than true altitude.
On a warm day, the expanded air is lighter than on a cold day, and consequently the pressure levels are raised. For example, the pressure
level where the altimeter indicates 10,000 feet will be higher on a warm day than under standard conditions. On a cold day the reverse is
true.
Question 3
4 / 4 pts
V(NE).
V(A).
V(LO).
V(A) is design maneuvering speed.
IncorrectQuestion 4
0 / 4 pts
a right turn is entered from a north heading.
an aircraft is accelerated while on a north heading.
a left turn is entered from a north heading.
If on a northerly heading and a turn is made toward east or west, the initial indication of the compass lags, or indicates a turn in the
opposite direction.
Question 5
4 / 4 pts
When density altitude is higher than indicated altitude.
In colder than standard air temperature.
In warmer than standard air temperature.
True altitude will be lower than indicated altitude in colder than standard air temperature, even with an accurate altimeter set to 29.92.
How do variations in temperature affect the altimeter?
Which V-speed represents maneuvering speed?
In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the west if
Under what condition will true altitude be lower than indicated altitude?

3/7
IncorrectQuestion 6
0 / 4 pts
The compass will initially indicate a turn to the left.
The compass will remain on south for a short time, then gradually catch up to the magnetic heading of the airplane.
The compass will indicate a turn to the right, but at a faster rate than is actually occurring.
If you are on a southerly heading and roll into a standard-rate turn to the right, the compass will immediately indicate a turn toward the west
(to the right) because of the northerly turning error. During the first part of the turn, it will show a faster rate of turn than you are actually
making.
Question 7
4 / 4 pts
V(LO).
V(LE).
V(FE).
V(LE) is the maximum calibrated airspeed at which the airplane can be safely flown with the landing gear extended.

opposite direction.

magnetic variation.
The angular difference between magnetic north, the reference for the magnetic compass, and true north is variation.
Question 11
4 / 4 pts
Airspeed indicator.
Vertical-speed indicator.
Altimeter.
The pitot tube provides input for the airspeed indicator only.
Question 12
4 / 4 pts
V(FC).
V(LOF).
V(FE).
V(FE) is the highest calibrated airspeed permissible with the wing flaps in a prescribed extended position.
IncorrectQuestion 13
0 / 4 pts
absolute altitude at field elevation.
calibrated altitude at field elevation.
true altitude at field elevation.
The local altimeter setting corrects for the difference between existing pressure and standard atmospheric pressure. Whether local pressure
is higher or lower than standard, it will indicate true altitude (MSL) at ground level, when the aircraft altimeter is set to the local altimeter
setting (assuming no setting scale error).
Question 14
4 / 4 pts
65 knots.
100 knots.
165 knots.
The flap operating range is marked by the white arc. The high end is V(FE) (maximum flap extended speed), which is 100 knots for this
airplane.

The pitot system provides impact pressure for which instrument?
Which V-speed represents maximum flap extended speed?
Altimeter setting is the value to which the barometric pressure scale of the altimeter is set so the altimeter indicates
(Refer to Figure 4.) What is the maximum flaps-extended speed?

55 to 208 knots.
55 to 165 knots.
55 to 100 knots.
The flap operating range is marked by the white arc. The low end is V(SO) (stall speed in a landing configuration), and the high end is
V(FE) (maximum flap extended speed).
Question 16
4 / 4 pts
Never-exceed speed.
Maneuvering speed.
Maximum structural cruising speed.
Maneuvering speed (V(A)) is not displayed on the airspeed indicator.
Question 17
4 / 4 pts
The altimeter, airspeed indicator, and turn-and-slip indicator.
The altimeter, airspeed indicator, and vertical speed indicator.
The altimeter, attitude indicator, and turn-and-slip indicator.
Airspeed, altimeter and vertical speed all receive static input and would indicate inaccurately if the static sources became plugged.
Question 18
4 / 4 pts
periodically realigned with the magnetic compass as the gyro precesses.
calibrated on a compass rose at regular intervals.
set prior to flight on a known heading.
Because the heading indicator is run by a gyroscope instead of a magnetic source, precession will cause creep or drift from a heading to
which it is set. It is important to check the indications frequently and reset the heading indicator to align it with the magnetic compass when
required.
IncorrectQuestion 19
0 / 4 pts
Atmospheric pressure lower than standard.
Air temperature lower than standard.
Air temperature warmer than standard.
(Refer to Figure 4.) What is the full flap operating range for the airplane?

(Refer to Figure 6.) To receive accurate indications during flight from a heading indicator, the instrument must be

6/7
The altimeter will indicate a lower altitude than actually flown, in air temperature warmer than standard.
Question 20
4 / 4 pts
the aircraft is decelerated while on a west heading.
a left turn is entered from an east heading.
a right turn is entered from a west heading.
While on an east or west heading, an increase in airspeed or acceleration will cause the compass to indicate a turn toward the north and a
deceleration will cause the compass to indicate a turn to the south. If on a north or south heading, no error will be apparent because of
acceleration or deceleration. (Remember ANDS = Accelerate North Decelerate South).
Question 21
4 / 4 pts
Upper limit of the green arc.

produce an additional error which is referred to as deviation.
IncorrectQuestion 23
0 / 4 pts
By the relationship of the miniature airplane (C) to the deflected horizon bar (B).
By the direction of deflection of the horizon bar (B).
By the direction of deflection of the banking scale (A).
