BK90 area pattern codes

[Swiso]

Hi guys,

I have one question in regard as when to input the desired area pattern in the TAKT function of CK37.

It is possible (recommended) at start-up just after 9099+LS ? just after the last waypoint before the TGT ?

 

How would you do if, let say, want to attack two targets, each with two BK90 and each TGT with a different area pattern ?

This is what I presume the procedure it will be, correct me if I am wrong:

 

at start-up, after REF/LOLA 9099+LS, I press the B button of the first TGT, TAKT, IN, put 922+LS, OUT, go to AKT/POS, then choose the B of next TGT, TAKT, IN, put 921+LS, OUT, go to AKT/POS.

 

Is that correct ? Or you will do these steps right between last waypoint and TGT ?

 

Thanks for any input or suggestions !

BK 90 pattern is not connected with waypoints in any way(targeting is!!). When you press the trigger programed pattern will be released.

Yes,that is correct:thumbup:

I configure my weapons after take off,but i don't see any reason why you couldn't configure pattern(or weapons) just after startup(after 9099+LS).So,it is possible-it works;is it recommended?....i can honestly say i do not know.

I do assume when you say TGT you are talking about target waypoint(M),and not the individual target.

Hi! Thank you for the help.

Yes, sorry, by TGT I mean the "M" waypoints.

 

On the situation I mention above, I was thinking, for example, of a flight plan lime this :

LS,B1,B2,B3,M4,B5,B6,M7,B8,B9,L1.

 

When you say that BK90 pattern is not connected with waypoints, you mean "B" waypoints ?

 

I was referring to the B4 and B7 buttons of the Ck37, which in this flightplan, represent the two targets waypoints.

 

So the procedure would be as indicated above, but the B button of the first target would be the B4 and the second the B7.

 

Is that right ?

Thanks !

No, the BK90 pattern is not connected to any waypoint in any way. There is just no relation at all between the pattern setting and waypoints. The BK90 will always be released in the pattern that you have entered before. If you attack want to attack M4 with a long pattern and M7 with a wide pattern you enter 92100 before dropping the BK90 on M4 and after that you enter 922000 before dropping on M7.

I mean waypoints in general.B,M...does not matter.When you are configuring release pattern you are telling computer how you wish your ordinance to be released,regardless of what waypoint you have selected,that's all.

In your case B4 will select M4(As you have configured B4 to be a target point).

You have already setup BK90 wide pattern:

TAKT, IN, put 922+LS, OUT, go to AKT/POS

After attack on first set of targets at waypoint 4(TGT point-M4), put safety on and master mode to mode NAV.

Than you continue with a flight plan and you can change BK90 pattern to long,at any point before attack on a second set of targets located at waypoint 7 (TGT point-M7).

TAKT, IN, put 921+LS, OUT, go to AKT/POS

Of course:thumbup:.

You will not get a valid targeting information if that is not the case.

Ah ! That's what I wanted to understand.

Now is clear.

Basically, set the area pattern before release.

Thanks !

Yes, although that doesn't have to be immediately before release. It can be at any time between startup and release and with any waypoint selected, as it doesn't care about waypoints. So you can entere the pattern right after takeoff with B1 selected and when you arrive at M4 you can drop in that pattern.

Now its clear !

Thank you very much !

 

Of course it would have been nice to be able to select the pattern in relation to the waypoint...less work to do when starting an attack run. :)

That's why you already should set the pattern way before starting the attack run (e.g. immediately after takeoff)! So there is no need to do that immediately before starting an attack run.

There is actually a certain problem with the bk90, it is the altitude select. not matter what altitude I select in the 92xxxx code(I tried 50m 200m 300m 500m), the bk90 only approach in a certain altitude.

The problem is you used the wrong code.

The actual code is 91XXX. (where XXX is the desired altitude)

Then you have to put the switch VALB-STD on VALB.

If you let the switch on STD, the weapon will "fly" at the standard parameter which is 60m.

 

I suggest you take a look at these two files, they are quite helpful:

Altitude selection is no longer possible anymore:

Yes since the Bk90 was updated a while ago this feature is no longer available.

Thank you for the information. By the way, in reality does this function exist?

 

Because the submunitions are attached with parachutes, it seems that different altitude approach cannot change the spread area, it is used to avoid terrain or obstacles?

Yes, the altitude selection is just for the approach to avoid terrain or obstacles, not for the terminal phase, which has a fixed altitude of 50m IIRC.
