Flight Instruments

Which V-speed represents maneuvering speed?

V(A)

Which V-speed represents maximum flap extended speed?

V(FE)

Which V-speed represents maximum landing gear extended speed?

V(LE)

V(NO) is defined as the

maximum structural cruising speed

V(SO) is defined as the

stalling speed or minimum steady flight speed in the landing configuration

Which would provide the greatest gain in altitude in the shortest distance during climb after takeoff?

V(X)

After takeoff, which airspeed would the pilot use to gain the most altitude in a given period of time?

V(Y)

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

The elevation of the departure area

Prior to takeoff, the altimeter should be set to which altitude or 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 cruising flight level?

18,000 feet MSL

If the pitot tube and outside static vents become clogged, which instruments would be affected?

The altimeter, airspeed indicator, and vertical speed indicator

Which instrument will become inoperative if the pitot tube becomes clogged?

Airspeed

Which instrument(s) will become inoperative if the static vents become clogged?

Airspeed, altimeter, and vertical speed

Altimeter setting is the value to 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

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 indicated altitude

The pitot system provides impact pressure for which instrument?

Airspeed indicator

What does the red line on an airspeed indicator represent?

Never-exceed speed

What is an important airspeed limitation that is not color coded on airspeed indicators?

Maneuvering speed

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

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

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

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 decelerated 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 is actually occurring

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

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

Only in straight-and-level unaccelerated flight

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

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

When standard atmospheric conditions exist

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

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

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

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

In colder than standard air temperature

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

Air temperature warmer than standard

Deviation error of the magnetic compass is caused by

certain metals and electrical systems within the aircraft
