Input of distance into ASP.
1.Automaticaly from radar 400-2000m.
Switches position:GUN or RKTS,FIRE,AUT,GYRO,AIR,target is LOCKED
(green light is ON)
2.Constant input 600-650m.
Switches position:GUN or RKTS.FIRE.AUT,GYRO,AIR,LOCK is interrupted.
(green light is OFF)
So,when LOCK is lost and last distance was for example 1200m,ASP auto-
maticaly has set 600-650m.The needle in transp.scale 400-2000m fluent- ly goes to 600-650m.When a pilot has renewed LOCK of target,ASP has
set real distance.
3.Autmaticaly from radar 1-9km(for guided missiles)
Switches position:SS,RKTS,FIRE,AIR,target is LOCKED(green light is ON)
4.Constant input 483m.
It can be set as a radius of piper in mils by WINGSPAN inner scale on
topmost distance scale.
Switches position:SS,FIRE,AUT,AIR,GUN or RKTS,target is not LOCKED.
5.Minimal(fixed) distance 300m.
Switches position:FIRE,GUN,MAN,GYRO,AIR.Twist grip on throttle is set
fully forward(clockwise)-this is min. distance and the biggest diameter
of piper.Now we must set proper wingspan on outer scale HO 300m.
The red light BREAK OFF is on,gyroscope is automticaly dampered(slow
moving) The central dot of piper is nearly boresight line and a pilot must
have precisely frammed target.The target aspect is very small,so synchro-
nization of central dot of piper with target is very short(1-2sec)Firing is
performed by short ripple.Needle in distance scale 400-2000m is fully left.
6.Manual input of distance by optical rangefinder.
Switches position:GUN or RKTS,FIRE,MAN,GYRO,AIR.
Conditions:precisely setting of wingspan and precisely framed target.
7.Slant range input.
a.)by radar in fixed beam mode.(range scale 400-2000m)
Switches position:GUN or RKTS,FIRE,AUT,GYRO,GROUND.
b.)by slant range box.No radar used.
Switches position:the same.
The slant range is computed as a goniometrical function of height and
sinus of pitch angle.
