Concerning illum rockets (M257 rockets not LUU-2 illum flare 'bombs'). I understand the concept of rocket deployment via CCRP as outlined in the manual (p525). Set target as SPI, go rockets and set to CCRP, put the rocket target pip into the small CCRP solution queue, and wait for the number to be 0. When I do that I find myself 13miles from the target and the illum flares don't reach the target before deploying chute. It seems that 3nm is more like the chute deploy range. What am I doing wrong in deploying illum rockets?

It's a good thing that this is Early Access and we've all volunteered to help test and enhance this work in progress... despite the frustrations inherent in the task with even the simplest of software... otherwise people might not understand that this incredibly complex unfinished module is unfinished. /light-hearted sarcasm

Just had a play with illum rockets using CCRP and was getting similar results... I did discover tho everything seems to work fine at altitudes of around 4-5000ft. Maybe there is the presumption of altitude using the illum rockets in CCRP due to there being an optimal altitude for their use? Just a thought.

 

Edit- my bad, I thought there was a specific CCRP mode for illum rockets which doesn't seem to be the case.

Is there a DTOF setting for the rocket profile?

 

The only settings are HOT and Drag as seen in pic. Is there anyone that has a tried and true method of reliable M257 deployment?

From my knowledge, CCRP for rockets is calculating ballistics for ground impact, so deploying the illum rockets will always have an element of guess work on the pilots behalf. Illum rockets call be deployed quite well tho in CCRP by using the "0" solution cue not as a launch cue but more of a "pitch up and launch cue". Pitch up 5 deg or so, launch and the illum rocket should be right over the target. I can supply a trk if needed.

The CCRP point in the case shown above should be 3000' "height over target" (z+ modifier to the SPI) which should result in the rocket being directed to that offset point.

 

A fair number of weapon profile options don't work as of Beta3 (LGB ORP vs BAL for example). Perhaps this is another one of those.

Ah ha, thx Frederf ill test that out.

 

Edit: Tested HOT 1500 and 2500, both results ended with the rocket heading direct for the targets.. Looks like it is WIP.

Agreed. That must be why at a pitch+5 it had me firing 13nm out, HOT of 3000 wasn't calculated and the trajectory was for ground level. But then again, I did also set the SPI to the WP (3000'), and set HOT to 0' to see if that made a difference, and it didn't. The algorithms for M257s must not be in the fire control system. Maybe both.. oh well, WIP. Thanks for testing guys.

This is a video I made... think that illumination rocket launch is just a question of practice... firing range is about 10km from target for effective deployment...

 

My WP is at arround 6000ft over taget... an the CCRP for M257 cue must be aiming at that point... :smilewink:
