AIRCRAFT GENERAL KNOWLEDGE (2)  INSTRUMENTATION

1   The purpose of the vibrating device of an altimeter is to:

     A    reduce the effect of friction in the linkages
     B    inform the crew of a failure of the instrument
     C    allow damping of the measurement in the unit
     D    reduce the hysteresis effect

2   The error in altimeter readings caused by the variation of the static pressure near the source
    is known as:

     A    instrument error.
     B    hysteresis effect.
     C    position pressure error
     D    barometric error.

3   VFE is the maximum speed:

     A    with the flaps extended in a given position.
     B    with the flaps extended in landing position.
     C    at which the flaps can be operated in turbulence.
     D    with the flaps extended in take-off position.

4   The airspeed indicator of a twin-engine aircraft comprises different sectors and colour marks.
     The blue line corresponds to the:

     A    minimum control speed, or VMC
     B    maximum speed in operations, or VMO
     C    optimum climbing speed with one engine inoperative, or Vy
     D    speed not to be exceeded, or VNE

5   Indication of Mach number is obtained from:

     A    Indicated speed and altitude using a speed indicator equipped with an altimeter type
          aneroid
     B    An ordinary airspeed indicator scaled for Mach numbers instead of knots
     C    A kind of echo sound comparing velocity of sound with indicated speed
     D    Indicated speed (IAS) compared with true air speed (TAS) from the air data computer

6   In the building principle of a gyroscope, the best efficiency is obtained through the
    concentration of the mass:

     A    on the periphery and with a high rotation speed.
     B    close to the axis and with a high rotation speed.
     C    on the periphery and with a low rotation speed.
     D    close to the axis and with a low rotation speed.

7   Concerning the directional gyro indicator, the latitude at which the apparent wander is equal to
     0 is:

     A    the equator
     B    latitude 30°
     C    latitude 45°
     D    the North pole
