Question 1

On a standard airspeed indicator, the yellow arc represents which speed range?

Accepted Answer

Caution range — smooth air only

Answer

The yellow arc is the caution range, meaning the aircraft should only be operated within it during smooth (non-turbulent) air conditions.

Question 2

When the miniature aircraft symbol on an attitude indicator appears above the artificial horizon bar with wings level, the aircraft is in what attitude?

Accepted Answer

Nose-high (climbing) attitude

Answer

The position of the miniature aircraft above the horizon bar on an attitude indicator indicates a nose-high or climbing pitch attitude.

Question 3

A heading indicator displaying '270' means the aircraft is flying in which direction?

Accepted Answer

West

Answer

On a heading indicator, 270 degrees corresponds to due west, following standard compass rose conventions.

Question 4

The red radial line on an airspeed indicator marks which critical speed?

Accepted Answer

Never-exceed speed (Vne)

Answer

The single red radial line (redline) on an airspeed indicator marks the never-exceed speed (Vne), which must never be exceeded in any flight condition.

Question 5

When the vertical speed indicator (VSI) needle points to the +2 mark, what is the aircraft's rate of climb?

Accepted Answer

2,000 feet per minute

Answer

The VSI is calibrated in thousands of feet per minute, so the +2 mark indicates a climb rate of 2,000 feet per minute.
