Of course Harle,no problém.

I performed bomb run (no aiming on target) only for release sequence.Weapon selector in position B 1-4,MBD2-67 on py- lon 1-2,single bomb on 3-4.Simultion time decelerated (L-CTRL,L-WIN,Z en.kybrd)Sequence is bad. Real life sequence is here.

In real life this ASP have not ability to computed continuously computed impact point.Pilot simply opened bomb chart,found proper bomb,for example FAB-500 .For this bomb,there are value of aiming angle,altitude, dive angle ,velocity and loft.The aiming angle pilot must to set on aiming angle scale of ASP,next set B and MAN.It is all.Aiming angle for this ASP is 0-11 degree.You can forget CCIP.

This is common feature for all gyro-gunsight.

Keep calm,keep calm friends and any invective please.Co-operation will be better.

ASP-PF-21 was used on 21M,MA ASP-PFD-21 was used on 21MF,BIS and MIG-23UB

Yes,weapon systems are the same from 21M version to 21BIS with a little difference. Attention- big difference is in guided missiles .

Personaly sources

Of course the biggest ring is not a part of piper,it only helped me to draw picture.

When mirror of gyroscope is spun by el.motor and piper is light up,we can see something like this.Evry diamonds and central dot of piper must draw a ring.From start big,then fluently smaller and smaller until piper reached full stabilization(3-4sec)-dampering button not used.

It can be interesting.Distance between pilot's eyes and glass of sight head.

Fixed net There is small cross under boresight line(11 mils)This is aiming point for firing by gun on ground targets. The position of this cross is computed for those conditions: dive angle- 35 degree A/C velocity- 800 km/h target distance- 1500m So,there is possibility to use two weapons in one attack.

Angle scale. In real sight this scale is used for setting vertical aiming angle for GUN or RKTS,in GROUND mode. Switches position:GUN-RKTS,FIRE,AUT-MAN,GYRO,GROUND,slant range can be from radar or from slant range box. When we will be switching between GUN or RKTS position(AUTO-mode),we can see piper movement from boresight(0 degree) downward,acording ball. box of RKTS(we can see position on angle knob) When we are in MAN mode,we can seet its manualy by hand. This vertical aiming angle is set by two-way mirror. In AIR mode. Switches position:SS,AUT,RKTS,FIRE,AIR and SARH missiles(only)vertical aiming angle will be set on 3degree downward from boresight.This is fixed value for each SARH missile. Reason:Boresight line and beam line must be parallel,so missile can fly into radar beam. Bombing mode. Switches position:B,MAN,SS. The pilot manualy set vertical aiming angle according to bomb chart.
