     (b)  To raise the undercarriage

          The lever is pushed forward, but it must first be pulled
          back and then across to disengage it from the gate.
          When the undercarriage is raised and locked, the lever
          will spring into the forward gate.

     (c)  To lower the undercarriage

          The lever is pulled back, but it must be pushed forward
          and then across to disengage it from the gate.  When

     (d)  Electrical visual indicator

          The electrically operated visual indicator (22) has two
          semi-transparent windows on which the words UP on a red
          background and DOWN on a green background are lettered;
          the words are illuminated according to the position of
          the undercarriage.  The switch for the DOWN circuit of
          the indicator is mounted on the inboard side of the
          throttle quadrant and is moved to the ON [position by
          means of a striker on the throttle lever;  this switch
          should be returned to the OFF position by hand when
          the aeroplane is left standing for any length of time.
          The UP circuit is not controlled by this switch.
          
     (e)  Mechanical position indicator

          A rod that extends through the top surface of the main
          plane is fitted to each undercarriage unit.   When the
          wheels are down the rods [protrude through the top of
          the main planes and when they are up the top of the
          rods, which are painted red, are flush with the main
          plane surfaces.
          
     (f)  Warning horn

          The push switch controlling the horn is mounted on the
          throttle quadrant and is operated by a striker on the
          throttle lever.  The horn may be silenced, even though
          the wheels are retracted and the engine throttled back,
          by depressing the push button (9) on the side of the
          throttle quadrant.  As soon as the throttle is again
          advanced beyond about one quarter of its travel the
          push-button is automatically released and the horn will
          sound again on its return.
