PART 1-DESCRIPTIVE

      (b) All leads incorporate quick releases which are auto-
          matically broken on ejection.

      (c) As the seat is ejected a static line readies the barostatic
          time-delay mechanism. When the free descent reaches
          10,000 ft. or at once if ejection has taken place below that
          height and provided that the G-stop has not operated,
          the barostat removes an obstruction from the gear train
          of the mechanism allowing it to operate.

      (d) After three seconds (11 with G-stop fitted) the seat
          harness is released, the seat-stabilising drogues are freed
          and by a connecting lifting line the face screen is dis=
          connected and the parachute deployed. The occupant is
          momentarily prevented from leaving the seat by two
          restraining straps until deployment of the parachute lifts
          him clear of the seat.
           

      OPERATIONAL CONTROLS

      43. Radar controls

      (a) Rebecca 8

          The control panel (39) is below the starboard gunsight
          and the indicator is below the port gunsight. When
          SRIM 2284 is embodied the indicator is moved to the
          position formerly occupied by the j.p.t. gauge.

       (b) I.F.F. controls

           The MANUAL ON/OFF and G/D switches (64) together
           with the central AUTO pushbutton are on the starboard
           wall.

       44. Radio controls

           The TR. 1934/1935 control unit (57) and changeover
           switch (52) is below the instrument panel. A mic./tel
           socket is attached to each seat and a press-to-transmit
           switch (6) is in the end of each throttle lever twist-grip.
A.L.1      The R/T muting switch (58) is below the altimeter.

       45. Gyro gunsights Mk. 5 (34)

           The GGS master retracting switches (23) (31) are on the
           inboard sides of the mountings. The selector dimmer
