  • 1

    Movement about the normal axis is called

    yawing’

  • 2

    Primary controls

    ailerons, elevator (or, in some installations, stabilator) rudder.

  • 3

    If aircraft moves in roll the axis it is moving about

    is Longitudinal

  • 4

    Stability of an aircraft

    is the tendency of the aircraft to return to its original trimmed position after having been displaced.

  • 5

    incorporation of an artificial stability mechanism, using sensors, computers and inputs to the aircraft’s trim or primary control systems

    this is known as active stability

  • 6

    If, after disturbance, an aeroplane initially returns to its equilibrium state.

    It has static stability and may be dynamically stable.

  • 7

    Moving the centre of gravity forward, away from the centre of pressure will

    increase longitudinal stability.

  • 8

    If horizontal stabilizer is re-positioned to a location further from the aircraft’s centre of gravity

    , it will Increase the aircraft’s longitudinal stability.

  • 9

    Dihedral

    is an outward and upward inclination of the wings to increases lateral stability.

  • 10

    Blanketing effect will increase

    lateral stability.

  • 11

    When an aeroplane with swept wings sideslips, the leading wing has

    greater span than the trailing wing.

  • 12

    Porpoising

    is a longitudinal instability.

  • 13

    If the aeroplane is loaded with the centre of gravity too far aft

    the aeroplane may assume a nose up rather than a nose down attitude.
