Best "brst" for NAVFLIR

[hotrod525]

Hello folks,

What are your best setting for boresighting NAVFLIR ? Whenever i start "hot", my NAVFLIR feel somewhat aligned, but whenever i do "cold" i have to boresight it.

I assume that depending on "pitch" you're either in "coaxial" mode ( at 0) or that pitch "zero" the FLIR to a "known distance" (IE: Pitch 15 will align at 15 nm -- i'm making this up to demonstrate).

On the backseat there is a post-it that say "Pitch 1.0" but it dosent feel like it.

 

Thanks'

6.4 is what I use.

Do you also have it so after rearming you need to set the pitch to +60?

Yeah I've seen that, keep meaning to report it. The alignment is different between ME loaded and Rearm loaded Navflirs.

Yeah i went to 60+ pitch trying to match up the alignement, it didnot worked well, so i was woundering if it was "my fault" or if it need some tweak from Raz

I've been doing 61. It's misaligned on the ground still but once in the air it's close enough.

For me so far it's 60-64 on pitch, and 2-4 on yaw.

When you say misaligned, do you mean in translation or rotation?

So just something to remember about the navflir pod. Its viewport is not coincident with the HUD POV. So while the FOV matches, the pod itself is located 10 feet below and 5 feet right of the cockpit (and 10-15 feet aft of the HUD) Basically what this means is there will always be some parallax. So far in DCS I have not had to do any yaw adjustment, however if it gets misaligned vertically a pitch boresight of 61 should line that up.

 

Additionally when boresighting it, do not use things close by to align the image with the outside world (hangars, taxiway symbols etc...) use distant objects like the horizon, clouds, far off objects etc. If you align it to objects close by (and especially if you add significant yaw values) then you are going to have an extremely messed up image up at altitude

Translation. I've never seen it misaligned in rotation yet. The pod itself being down and right of the cockpit would make one think the misalignment would always reflect such, but I've found it to not be, at least in the past.

Yes, i'm aware of the parralax and how it would affect an EO on a vehicle being on a turret or a pod on a plane, but the fact (or the impression) is if you start "hot" you're align in a way that is hardly (?) acheivable. So, i was woundering if there was any efficient setting use around so it dont struggle much with it. lol.
