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

Select the correct answer(s).

(0/0)

Explanation

Magnetic dip causes turning and acceleration/deceleration errors. For this reason, magnetic compass indications are accurate only in straight-and-level unaccelerated flight.

If the outside air temperature (OAT) at a given altitude is warmer than standard, the density altitude is

Select the correct answer(s).

(0/0)

Explanation

When the OAT is warmer than standard, the density altitude (DA) is higher than pressure altitude.

What are the standard temperature and pressure values for sea level?

Select the correct answer(s).

(0/0)

Explanation

The standard atmosphere is a temperature of 15°C (59°F) and 29.92” Hg (1013.2 millibars)

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

Select the correct answer(s).

(0/0)

Explanation

Each .1” change on the altimeter settings equates to about 100 feet. In this case, change .15 lower, or 150 feet.

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

Select the correct answer(s).

(0/0)

Explanation

Pressure altitude equals true altitude when standard atmospheric conditions exist. When nonstandard conditions exist, true altitude will not equal pressure altitude.

370953

none

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

Select the correct answer(s).

(0/0)

Explanation

Since density altitude is pressure altitude corrected for nonstandard temperature, DA and PA are equal only at standard temperature

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

Select the correct answer(s).

(0/0)

Explanation

The aircraft will be at a higher true (actual) altitude above sea level than is indicated. In other words, the altimeter will indicate lower than the actual altitude.

none

If a flight is made from an area high pressure into an area of low pressure without the altimeter setting being adjusted, the altimeter will indicate

Select the correct answer(s).

(0/0)

Explanation

Remember, “from high to low, look out below,” In other words, the aircraft will be at a lower true (actual) altitude than indicated, so the altimeter indicates higher than actual.

none

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

Select the correct answer(s).

(0/0)

Explanation

When the air is colder than standard, the aircrafts’ actual (true) altitude will be lower than indicated.

370957

none

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

Select the correct answer(s).

(0/0)

Explanation

When the air is colder than standard, the aircraft’s actual (true) altitude will be lower than indicated. In this question, the air temperature is warmer than standard, so indicated altitude will be lower than actual (true) altitude.

Which factor would tend to increase the density altitude at a given airport?

Select the correct answer(s).

(0/0)

Explanation

The angular difference between true north and magnetic north is

Select the correct answer(s).

(0/0)

Explanation

Magnetic variation occurs because the earth’s magnetic poles do not coincide with its geographic poles. You can determine local magnetic variation by referencing the isogonic lines on aeronautical charts, which are represented by dashed magenta lines.

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

Select the correct answer(s).

(0/0)

Explanation

An acronym to easily remember acceleration errors is ANDS (Accelerate North Decelerate South). Acceleration errors occur primarily due the counter weights added to offset magnetic dip.

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?

Select the correct answer(s).

(0/0)

Explanation

A turn from a southerly heading, results in a compass indication in the correct direction, but leading the actual heading. Various compass errors arise due to magnetic dip and from the compass counter weights added to offset dip.

none

When converting from true course to magnetic heading, a pilot should

Select the correct answer(s).

(0/0)

Explanation

Remember, “East is least, West is best” to recall that easterly variation is subtracted and westerly is added. This calculation is often performed in conjunction with wind correction calculations using the formula. TC ± WCA = TH ± VAR = MH ± DEV = CH When
