Lesson 3 – Flight Instruments

Question 1

The turn coordinator provides an indication of
A—the movement of the airplane about the yaw and roll axes.
B—the angle of bank to but not exceeding 30º.
C—attitude of the airplane with reference to the longitudinal axis.

Question 2

To receive accurate indications during flight from a heading indicator the instrument must be
A—set prior to flight on a known heading.
B—adequately powered so that it seeks the proper directions.
C—periodically realigned with the magnetic compass as the gyro precesses.

Question 3

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.

Question 4

Deviation in a magnetic compass is caused by
A—the difference in the location between true north and magnetic north
B—magnetic ore deposits in the Earth distorting the lines of magnetic force.
C—magnetic fields within the airplane distorting the lines of magnetic force.

Question 5

In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the east if
A—an aircraft is accelerated while on a north heading.
B—a right turn is entered from a north heading.
C—a left turn is entered from a north heading.

Question 6

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.
B—Higher temperatures expand the pressure levels and the indicated altitude is higher than true altitude.
C—Lower temperatures lower the pressure levels and the indicated altitude is lower than true altitude.

Question 7

If it is necessary to set the altimeter from 29.15 to 29.85, what change is made on the indicated altitude?
A—70-foot increase.
B—700-foot increase.
C—700-food decrease.

Question 8

The pitot system provides impact pressure for only the
A—airspeed indicator, altimeter, and vertical speed indicator.
B—altimeter and vertical speed indicator.
C—airspeed indicator.

Question 9

Which V-speed represents maneuvering speed?
A—V(A)
B—V(LO)
C—V(NE)

Question 10

Refer to Figure 3-6 on Page 3–3. Which of the color-coded markings on the airspeed indicator identifies the never-exceed speed?
A—Upper limit of the white arc.
B—Upper limit of the green arc.
C—The red radial line.

Question 11

Refer to Figure 3-6 on Page 3–3. Which of the color-coded markings identifies the power-off stalling speed with wing flaps and landing gear in the landing position?
A—Upper limit of the white arc.
B—Lower limit of the green arc.
C—Lower limit of the white arc.

Question 12

Refer to Figure Q3-1. How should a pilot determine the direction of bank from an attitude indicator such as the one illustrated?
A—By the direction of deflection of the banking scale (A).
B—By the direction of deflection of the horizon bar (B).
C—By the relationship of the miniature airplane (C) to the deflected horizon bar (B).
