  • 1

    Dogtooth extensions, leading edge cuffs and vortillons are all designed to

    prevent wing tip stalling at low speed.

  • 2

    At small angle of attack the Cp is located between

    40 to 50% of the chord

  • 3

    If an aircraft with swept wings begins to tip-stall,

    it will pitch up.

  • 4

    Accretion of ice on

    a wing will increase stall speed.

  • 5

    An aeroplane which is contaminated with ice

    may stall before any stall warning is provided.

  • 6

    a disadvantage of high aspect ratio wing

    is poor stiffness characteristics.

  • 7

    The reason for the use of swept wing planform is their

    low drag at the higher speeds.

  • 8

    a vertical stabiliser has a further surface extending forward, on top of the fuselage, it is known

    as a dorsal fin.

  • 9

    The vertical stabiliser keeps the nose of the plane from swinging from side to side

    which is called yaw.

  • 10

    The angle of incidence of the wing is an angle

    formed by lines parallel to the chord line and longitudinal access

  • 11

    The hinged part of the horizontal stabiliser

    is called the elevator; it is used to deflect the tail up and down

  • 12

    The four forces acting in level flight are lift, weight, drag and thrust.

    The lift acts through the centre of pressure. The weight is through the centre of gravity.

  • 13

    the drag and thrust act along

    lines parallel to the longitudinal axis

  • 14

    When an aeroplane is in a climb, a component of the weight acts

    backwards along the flight path, and adds to the drag.
