Airplane Systems

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

• A – Air temperature lower than standard.

• B – Atmospheric pressure lower than standard.

• C – Air temperature warmer than standard.

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

• An increase in barometric pressure.

• An increase in ambient temperature.

• A decrease in relative humidity.

If the AHRS detects a problem with the integrity of the sensor information for the instruments on a PFD, what occurs?

• The system reverts to reversionary mode and PFD information is displayed on the MFD.

• A red X is placed over the display of the affected instrument (attitude indicator or HSI).

• After an alert message appears, you must determine the affected instrument by comparing the indications of all instruments.

You are flying an airplane with an integrated digital flight display and the PFD screen fails. What is a back-up options for the PFD instruments?

• Display the PFD instruments on the MFD screen.

• Monitor traditional back-up instruments that are powered from the main electrical bus.

• Reset the AHRS and the ADC and observe whether the PFD turns back on.

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

• equal to pressure altitude.

• lower than pressure altitude.

• higher than pressure altitude.

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

• 15°C and 29.92 inches Hg

• 59°C and 1013.2 millibars

• 59°F and 29.92 millibars

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

• Altimeter will indicate .15 inches Hg higher.

• Altimeter will indicate 150 feet higher.

• Altimeter will indicate 150 feet lower.

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

• When the atmospheric pressure is 29.92 inches Hg.

• When standard atmospheric conditions exist.

• When indicated altitude is equal to the pressure altitude.

In the Northern Hemisphere, a magnetic compass will 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, a magnetic compass will normally indicate initially a turn toward the east if:

• an aircraft is decelerated while on a south heading.

• an aircraft is accelerated while on a north heading.

• a left turn is entered from a north heading.
