A simple way to point Shkval at a known target in mountain areas

[Akiazusa]

Hi.

just to share a simple way to point Shkval at a known target in mountain areas,some of u may already known,but in case u don't

 

1. A known target,u need to know it's coordinates and elevation(in this case,the target(actually a friendly LAV25)is at 579m)

2.Enter it via PVI-800,as a target point,and select it via PVI-800.(note PVI800 uses Lat Long Decimal Minutes format,u can use LALT+Y to change the coordinates format displayed on the F10 map)

 

3.check ur local QNH,ur can check briefing in most case,but if the mission is using dynamic weather,u may want to find it urself.(ie.landing on a place which elevation is known,and set cockpit altimeter to match the ground elevation,then the altimeter pressure setting will be ur QNH)

 

4.use any calculator(u can find a lot via google),input target elevation and QNH(lines), convert them into target QFE (circle)

(meter and mmHg is used for ka50)

 

5.Input the target QFE in ur cockpit altimeter

 

6.!!!!!!FLY ABOVE 300 METERS AGL!!!!! (VERY IMPORTENT,since when above 300m AGL the yellow Shkval LOS line drawn on the ABRIS will use cockpit altimeter as the altitude reference,when below 300m AGL,radar altimeter reading will be used,u won't want that unless the terrain is perfectly flat,in that case just starting from step7)

 

7.uncage Shkval,since u can't enter altitude via PVI800,it will point at mean sea level,the target is lined up only horizontally,u need to adjust on vertical direction by urself.

 

8.focus on the ABRIS,adjust Shkval vertically,until the end of "yellow Shkval LOS line" is merged with the "blue target box",DON'T use laser rangefinder through out the whole process.

 

9.Bingo.(note the more altitude difference between u and the target,the more accurate it will be,also there will be some heading error due to INS drift)

also after u have found the target u can use range finder to make Shkval LOS fixed at it's position.
