PART V - ARMAMENT EQUIPMENT

                  (iii) Sight selector unit
                       The sight selector unit (115) on the armament panel has
                       three controls, the function selector lever, the rocket
                       setting lever, and the target speed switch:-
                       (a)  The function selector lever is set at either BOMB
                             GUN or ROCKET to adjust the sight for the
                             desired operation.  The lever will automatically
                             return to GUN when the radar target selector
                             button (73) on the control column is pressed.
                       (b)  The rocket setting lever is used to provide a depres-
                             sion angle correction for the type of rocket to be
                             fired and the intended dive angle of the attack.
                             Settings are provided for three types of rockets,
                             5" HVAR, 2.25" SCAR and 2.75"-FFAR.  At each
                             of the three positions are two gates, marked S and
                             N, for setting the intended dive angle.  For attacks
                             between 0 and 40 degrees the pilot sets the control
                             at N (normal) and for attacks between 40 degrees and
                             60 degrees he sets the control at S (steep).
                       (c)  The target speed switch is used for gunnery to
                             control deflection angle.  When a slow target is to be
                             attacked the switch is set at LO; when the speed
                             of the target is similar to the Sabre the switch is
                             moved to HI.  The TR position is used when firing
                             on a drogue or other training target.
                   (iv) Bomb/target wind control
                        The bomb/target wind control (116) is on the armament
                        panel and is used, when bombing, to compensate for the
                        components of wind velocity and target motion parallel to
                        the direction of the attacking aircraft.  For stationary
                        targets, corrections are made on the dial UPWIND (for
                        bombing run into a headwind) or DOWNWIND (when
                        bombing run is made with a tailwind) according to
                        estimated wind velocity.  If wind direction is not in line
                        with the course of the aircraft during a bombing run, the
                        amount of correction must be estimated.  When the
                        target is moving, additional correction must be made for
                        velocity of target.  For approaching targets, correction
                        is downwind, for receding targets, correction is upwind.
                        When the sight is used for firing rockets or guns, the
                        pointer should be on ROCKET/GUN.
                   (v) Radar target selector
                        When the radar detects a target, it locks on it and
                        measures its range.  The radar may be shifted to another
