PART I-DESCRIPTIVE

     46.  D.M.E. (Rebecca Mk. 7) ARI.5849
     
     (a)  The control unit (89) is on the starboard shelf. A range
          and heading meter (57), which indicates range and left
          right heading from the homing beacon, is on the star-
          board instrument panel.

     (b)  Three suppressed receiver aerials are fitted, one in each
          wing leading edge and one in the rear fuselage under-
          surface. A suppressed transmitter aerial is also inside
          the rear fuselage undersurface.
          

     47.  Gun firing

     (a)  The gun firing switch is on the forward face of the control
          column handgrip. The circuit is automatically isolated
          when the undercarriage is locked down. A butt test
          switch is in the starboard wheel bay and provides an
          override for the automatic isolation of the gun firing
          circuit.

     (b)  When the guns are fired, an electrically-operated selector
          is energized allowing hydraulic fluid to open the gun bay
          scavenging flap. This causes air to clear the gases from
          the link and empty case chutes. When the trigger is
          released the scoop closes and the air flow is cut off.

                   provided for the nose camera only. The windows of all three
                   cameras are protected by hydraulically-operated shutters.
