Aerospace lesson 2 chapter 2 test 2 study guide

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

in straight- and- level flight

Deviation in a magnetic compass is caused by the...

magnetic fields

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

pressure altitude

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

150 ft decrease

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

700 ft increase

What is absolute altitude?

AGL

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

Colder than standard temperature

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

What is pressure altitude?

Height of a standard datum plane of 29.92 inches of mercury

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 actual altitude

In the northern hemisphere, a magnetic compass will normally indicate initially a turn toward the east if...

Left turn is entered from a north heading

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...

Lower than actual altitude

What is true altitude?

MSL

What is the density altitude?

Pressure altitude corrected for non standard temperature

How do variation in temperature effect the altimeter?

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

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

Right turn is entered from a north heading

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

Standard temperature

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

Standard temperature 50 degrees celcius

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

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

Warmer than standard temperature

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

When standard conditions exit the altimeter if collaborated properly

In the northern hemisphere a magnetic compass will normally indicate a turn toward the north if...

aircraft is accelerated while on and east or west heading
