If an altimeter setting is not available before flight, to which altitude should the pilot adjust the altimeter?

The elevation of the departure airport

Prior to takeoff, the altimeter should be set to which altitude of altimeter setting?

The current local altimeter setting, if available, or the departure airport elevation.

At what altitude shall the altimeter be set to 29.92, when climbing to crushing flight level?

18,000 MSL

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

true altitude at field elevation

How do variations in temperature affect the altimeter?

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

What is true altitude?

The vertical distance of the aircraft above sea level

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

In colder than standard air temperature

What is absolute altitude?

The vertical distance of the aircraft above the surface

What is density altitude?

The pressure altitude corrected for nonstandard temperature

What is pressure altitude?

The altitude indicated when the barometric pressure scale is set to 29.92

Under what condition is indicated altitude the same as true altitude?

When at sea level under standard conditions.

If it is necessary to set the altimeter from 29.15 to 29.85, what change occurs?

700 foot increase in the indicated altitude

Under which condition will pressure altitude be equal to true altitude?

Then standard atmospheric conditions exist

Under what condition is pressure altitude and density altitude the same value?

At standard temperature

Of a flight is made from an area of low pressure into am area of high pressure with out the altimeter setting being 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

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

Air temperature warmer than standard

(Refer to Figure 3.) Altimeter 1 indicates

10,500 ft

(Refer to Figure 3.) Altimeter 2 indicates

14,500 ft

(Refer to Figure 3.) Altimeter 3 indicates

9,500 ft

(Refer to Figure 3.) Which altimeter(s) indicate more than 10,000 feet?

1 and 2 only

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

Altimeter will indicate 150 feet lower

(Refer to Figure 7.) How should a pilot determine the direction bank from an attitude indicator such as the one illustrated?

By the relationship of the miniature plane (c) to the deflected horizon bar (b)

(Refer to Figure 5.) A turn coordinator provides an indication of the

movement of the aircraft about the yaw and roll axis

(Refer to Figure 7.) The proper adjustment to make on the attitude indicator during level flight is to align the

miniature airplane to the horizon bar

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

periodically realigned with the magnetic compass as the gyro precesses

Deviation in a magnetic compass is caused by the

magnetic fields within the aircraft distorting the lines of magnetic force

The angular difference between true north and magnetic north is

magnetic variation

Deviation error of the magnetic compass is caused by

certain metals and electrical systems within the aircraft.

In the Northern Hemisphere, a magnetic compass will normally indicate a turn toward the north is

an aircraft is accelerated while on an east or west heading

In the Northern Hemisphere, the magnetic compass will normally indicate a turn toward the south when

the aircraft is decelerating 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 to the right, but at a faster rate than it is actually occurring

In the Northern Hemisphere, if an aircraft is accelerating or deceleration, the magnetic compass will normally indicate

correctly when on a north or south heading

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

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

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

Only in straight-and-level unaccelerated flight

In the Northern Hemisphere, if a glider is accelerated of decelerated, the magnetic compass will normally indicate

correctly only when on a north or south heading.
