On a standard airspeed indicator, the yellow arc represents which speed range?
Answer: Caution range — smooth air only
The yellow arc is the caution range, meaning the aircraft should only be operated within it during smooth (non-turbulent) air conditions.
When the miniature aircraft symbol on an attitude indicator appears above the artificial horizon bar with wings level, the aircraft is in what attitude?
Answer: Nose-high (climbing) attitude
The position of the miniature aircraft above the horizon bar on an attitude indicator indicates a nose-high or climbing pitch attitude.
A heading indicator displaying '270' means the aircraft is flying in which direction?
Answer: West
On a heading indicator, 270 degrees corresponds to due west, following standard compass rose conventions.
The red radial line on an airspeed indicator marks which critical speed?
Answer: Never-exceed speed (Vne)
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.
When the vertical speed indicator (VSI) needle points to the +2 mark, what is the aircraft's rate of climb?
Answer: 2,000 feet per minute
The VSI is calibrated in thousands of feet per minute, so the +2 mark indicates a climb rate of 2,000 feet per minute.
A turn coordinator showing the miniature aircraft symbol banked to the right indicates the aircraft is:
Answer: In a right turn
The turn coordinator's miniature aircraft symbol banks in the same direction as the actual turn, so banking right indicates the aircraft is turning right.
Which color arc on the airspeed indicator represents the safe flap-operating speed range?
Answer: White arc
The white arc on an airspeed indicator represents the flap operating speed range, from power-off stall speed with flaps extended (Vso) to maximum flap extension speed (Vfe).
