THE AIRSPEED INDICATOR

Question 1

A leak in the pitot total pressure line of a non-pressurized aircraft to an airspeed indicator would cause it to:

Answer 1

d. under-read

Question 2

A pitot blockage of both the ram air input and the drain hole with the static port open causes the airspeed indicator to:

Answer 2

c. react like an altimeter

Question 3

If the static line to the ASI becomes blocked during a long descent, a dangerous situation could arise due to the ASI:

Answer 3

a. overreading, this indicated speed falsely showing the aircraft to be further from the stalling speed than it actually is.

Question 4

An aircraft maintaining a constant CAS and altitude is flying from a cold airmass into warmer air. The effect of the change of temperature on the speed will be:

Answer 4

c. TAS will increase.

Question 5

The airspeed indicator is calibrated to:

Answer 5

b. conditions of the International Standard Atmosphere at MSL.

Question 6

Dynamic pressure is equal to:

Answer 6

a. 1⁄2ρv2

Question 7

Excluding blockages, the full list of errors of the ASI is:

Answer 7

d. instrument error, position error, density error, compressibility error, manoeuvre
induced error.

Question 8

Some ASIs have coloured arcs and lines marked on their dials. A yellow arc and a white arc indicate:

Answer 8

c. cautionary range and flap operating speed range.

Question 9

If the static line to the ASI becomes blocked during a climb, the ASI reading will:

Answer 9

b. progressively under indicate the value of airspeed.
