Getting back to Hornet after a break of many months...

 

Any answers to the following appreciated!

 

1. What is Mode S in the AIM-120 stores page?

2. How do you align the JHMCS cross so that it actually corresponds to a point on the HUD that you're looking at? For my setup, the default JHMCS symbology all sits below my eye line

 

Thanks in advance :joystick:

JHMCS doesn't need to align with the actual HUD. It needs to align with the aircraft. That's no something that you control. That's done by avionics technicians when they boresight and calibrate the system,

It's not about the HUD, it's about head position.

 

If I hold my head naturally and look at a target near the horizon, it's at eye level. As it passes to the side and out of the HUD, the JHMCS cursor (point of interest) is below it, such that I need to tilt my head back and look down my nose at it, so the aircraft sensors track it.

 

I can keep looking down my nose as it passes back and forth between HUD and JHMCS but it seems unnecessary and something that would be adjustable in the real aircraft.

Wags stated that the placement of the JHMCS display is accurate and it seems it won't be changed. Just have to get used to it I guess. Its beem griped on before.

I'm afraid that's incorrect. JHMCS has to be boresighted every time it is used, and it is done by the pilot (and WSO, as applicable) by lining up a cross in the visor with a cross in the HUD.

I got a finsky says it won't because it's a sim and you don't need to calibrate a simulated helmet in a simulated aircraft in a simulated environment. You can however recenter your Oculus Rift or TrackIR 5 or Vive or whatever.

 

With my setup, I can center TrackIR for either the HMS or the overall cockpit view. When I center for the HMS, i lose visibility of my DDIs.

When you are in the pit turn on the JHMCS. Notice that the JHMCS symbology is well below eye level. Look down in the pit at the color MPCD (the one behind the stick) and place the JHMCS cross hair in the center of the MPCD screen and recenter the track IR. Now the JHMCS will be perfect eye level and "calibrated". Just give it a try.

The placement is dead center. Problem is the default view is looking down instead of straight ahead. Center TrackIR while looking straight ahead and the JHMCS will tell you it's pointed like 13º down.

Hey, Steve.

 

Unrelated: THANK YOU for your work on (assuming I've got the right guy :-)) on "Eagle Engaged!" :thumbup: Any chance you could use any pull you might have around here to get us a proper, full-fidelity Albino Eagle in DCS? :-)

Thanks! I have precisely zero pull around here, but I'd certainly pay for a full-up Albino Eagle simulation. :pilotfly:

Right now it's a bit like aiming the JHMCS with your mouth rather than eye. A realignment would be great.

 

 

This.

I would also like a way to calibrate the center of the JHMCS, as I also need it to be higher on the screen.

 

I was also thinking it would be cool if the JHMCS could be programmed to move the image around on the screen based on where trackIR reported your head was actually pointing. So if I'm looking over my right shoulder in game, IRL my eyes would be near the edge of the monitor, and the JHMCS would be programmed to move to the edge of my monitor.

In theory, with calibration, it should be able to work, but..... TrackIR is already pretty meta, adding an additional layer of meta COULD get really complicated.

 

Or it could end up being really cool. Part of learning to use trackIR means you have to keep your eyes forward and only move your head, something that even now I can have trouble with. If ED could get the image to move where you're looking on your monitor they could sell it as a way to train yourself to use trackIR.

 

As far as calibrating the JHMCS in game, when I read through that part of NATOPS my understanding was that it was only to align the helmet display with the world outside. It didn't sound like you could move the image up or down for pilot preference, which is what we need.

And I was reading pretty carefully because that is exactly why I looked it up in the first place.

What WSO? This is a single seat jet.

 

Your response to me was that in real life, avionics techs did the alignment. My response was that in real life, that's not correct. To complete the triptych of real life examples, I referenced the pilot and WSO doing the alignment before each flight. Which part of that has thrown you?

Perhaps you can take a long walk off a short pier.

 

Hi Trev

 

There appears to be a little confusion over the original question. Steve's response was to you stating that "JHMCS doesn't need to align with the actual HUD. It needs to align with the aircraft. That's no something that you control. That's done by avionics technicians when they boresight and calibrate the system,"

 

I'm not sure how alignment works in the sim, but in the real F-15C (and I assume it's the same for other JHMCS equipped jets), JHMCS alignment forms part of the pilots normal preflight checks, so Steve is correct about that. As for Cosmic_AK's DCS, TrackIR info on alignment using the MPCD, I'm sure many users will find that helpful. :)

 

1. What is Mode S in the AIM-120 stores page?

 

Steve, I wish I knew. I think it's one of those hush-hush modes because in the Eagle manual, it refers the reader to the triple sticks.

Does this work with Rift too, or only with Trackir?

Understood. I'm a fan of your work, for sure. There's a photo of yours that looks like you're in the back seat of an F-15B (or D?) at night landing at Nellis... and the MFCD in the front is illuminated with what looks like Link-16 stuff... just made me long for a full-fidelity, single-seat, C model. :-) How many fast-jet rides would you estimate you've taken? Sorry...off-topic.
