Private Flight Instruments

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

• A. calibrated altitude at field elevation.
• B. absolute altitude at field elevation.
• C. true altitude at field elevation.

(Refer to Figure 3.) Altimeter 3 indicates

• A. 9,500 feet.
• B. 10,950 feet.
• C. 15,940 feet.

The pitot system provides impact pressure for which instrument?

• A. Altimeter.
• B. Vertical-speed indicator.
• C. Airspeed indicator.

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

• A. If the altimeter has no mechanical error.
• B. When at sea level under standard conditions.
• C. When at 18,000 feet MSL with the altimeter set at 29.92.

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

• A. a left turn is entered from a west heading.
• B. an aircraft is decelerated while on an east or west heading.
• C. an aircraft is accelerated while on an east or west heading.

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

• A. In colder than standard air temperature.
• B. In warmer than standard air temperature.
• C. When density altitude is higher than indicated altitude.

Deviation in a magnetic compass is caused by the

• A. presence of flaws in the permanent magnets of the compass.
• B. difference in the location between true north and magnetic north.
• C. magnetic fields within the aircraft distorting the lines of magnetic force.

What is pressure altitude?

• A. The indicated altitude corrected for position and installation error.
• B. The altitude indicated when the barometric pressure scale is set to 29.92.
• C. The indicated altitude corrected for nonstandard temperature and pressure.

What is an advantage of an attitude indicator that is displayed digitally?

• A. It is more sensitive than the analog instrument.
• B. The indicator can be moved to any place around the PFD.
• C. The horizon line extends all the way to the edges of the PFD.

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

• A. movement of the aircraft about the yaw and roll axes.
• B. angle of bank up to but not exceeding 30°.
• C. attitude of the aircraft with reference to the longitudinal axis.
