FAA Flight Instrument Test 1

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

A. The altimeter, airspeed indicator, and turn-and-slip indicator.

B. The altimeter, airspeed indicator, and vertical speed indicator.

C. The altimeter, attitude indicator, and turn-and-slip indicator.

Correct! Wrong!

The pitot tube is connected to the airspeed indicator. The static vents (or ports) are connected to the airspeed indicator, altimeter, and the vertical speed indicator. Answers A and C are incorrect because the turn-and-slip indicator is not connected to the pitot-static system.

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

A. Altimeter.

B. Vertical speed.

C. Airspeed.

Correct! Wrong!

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

A. Airspeed only.

B. Altimeter only.

C. Airspeed, altimeter, and vertical speed.

Correct! Wrong!

Altimeter 1 indicates

A. 500 feet.

B. 1,500 feet.

C. 10,500 feet.

Correct! Wrong!

Altimeter 2 indicates

A. 1,500 feet.

B. 4,500 feet.

C. 14,500 feet.

Correct! Wrong!

Altimeter 3 indicates

A. 9,500 feet.

B. 10,950 feet.

C. 15,940 feet.

Correct! Wrong!

Which altimeter(s) indicate(s) more than 10,000 feet?

A. 1, 2, and 3.

B. 1 and 2 only.

C. 1 only.

Correct! Wrong!

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.

Correct! Wrong!

How do variations in temperature affect the altimeter?

A. Pressure levels are raised on warm days and the indicated altitude is lower than true altitude.

Higher temperatures expand the pressure levels and the indicated altitude is higher than true altitude.

Lower temperatures lower the pressure levels and the indicated altitude is lower than true altitude

Correct! Wrong!

What is true altitude?

The vertical distance of the aircraft above sea level.

The vertical distance of the aircraft above the surface.

The height above the standard datum plane.

Correct! Wrong!

What is absolute altitude?

The altitude read directly from the altimeter.

The vertical distance of the aircraft above the surface.

The height above the standard datum plane.

Correct! Wrong!

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.

Correct! Wrong!

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.

Correct! Wrong!

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

A. 70-foot increase in indicated altitude.

B. 70-foot increase in density altitude.

C. 700-foot increase in indicated altitude.

Correct! Wrong!

The pitot system provides impact pressure for which instrument?

A. Altimeter.

B. Vertical-speed indicator.

C. Airspeed indicator.

Correct! Wrong!

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.

Correct! Wrong!

To receive accurate indications during flight from a heading indicator, the instrument must be

A. set prior to flight on a known heading.

B. calibrated on a compass rose at regular intervals.

C. periodically realigned with the magnetic compass as the gyro precesses.

Correct! Wrong!

The proper adjustment to make on the attitude indicator during level flight is to align the

A. horizon bar to the level-flight indication.

B. horizon bar to the miniature airplane.

C. miniature airplane to the horizon bar.

Correct! Wrong!
