HUD Pitch Ladder

[Shahriar0]

I have a question regarding the pitch ladder in the HUD. How come the 0 degree pitch is not over the horizon line? (see the attached photo. The pitch ladder in VDI, the VSI, and the Attitude Indicator they all show level flight but the solid pitch ladder in the HUD, which I primarily use to fly, is way below the horizon line?

 

I understand it can be trimmed via the HUD TRIM, but shouldn't that be over the horizon line by default when a mission is started?

 

Thanks.

In your picture the aircraft's water line actually is resting on the horizon line, but the representation of the aircraft's attitude has been artificially lowered in the HUD by five degrees to make it more readable by the pilot. This was a deliberate design choice by Grumman due to side effects of the HUD being projected directly onto the windscreen. The aircraft's true waterline, that is where the nose is actually pointing, is about where the heading carrot is.

 

This seems more extreme because in cruise and A/A mode, the representation of attitude is compressed so it shows every 30 degrees of attitude instead of every 5 degrees like in landing, take off, and A/G. Generally speaking this is a very early HUD, and is meant as a tool for weapons employment. It's not really intended to be precision navigation instrument like some later examples.

Thanks for the detailed explanation. As long as this was by design, I can live with that. I, myself, like to rest it on the horizon on cruise. It makes making level turns so much easier.

Our SMEs would sometimes turn it off during a case 1 to get all the distracting stuff out of the way, haha. :smilewink:

Haha, to me more is better :) But thanks for the tip.

HUD Pitch Ladder

 

It eventually got a modern HUD called the SparrowHawk but those were only installed a couple years before retirement. What we have now represents what the plane looked like over pretty much the entirety of its service life.

IronMike, I don't see the HUD TRIM knob listed as function that can be mapped to keys (to raise and lower the pitch ladder.) Is it possible to support this so we are not forced to use mouse to control it? Having the ability to use Hotas would a great help for VR users, and much appreciated.

 

Thanks.

Would ED care to comment on this mini-feature request?

 

Thanks.

Thanks.

 

Why would ED comment on a request for a feature on a module that they didn't develop?

[Shahriar0]

Obviously, I meant Heatblur (I had another bug going on with ED so I got them confused.) No big deal. I am sure HB knows my comment was addressed to them.

[IronMike]

Check the input binding request list in the bug section and add it please, if it is not in already. We will do all inputs that are missing at the very end.

[Shahriar0]

Done.

 

I searched through the pages and didn't find one so I added the request.

 

Thanks.

I'd suggest that the time to have the waterline be as accurate as possible is during the landing phase.  For that reason, I'd recommend setting the HUD waterline to match the actual horizon prior to launch (and prior to kneeling the jet), and then not touching it again for the duration of the flight, that way when you're in the landing pattern, you know you're getting good info.

damn i cant imagine trying to land it without needles or flight path marker

HUD ladder brightness knob doesn’t seem to do anything for me, am I missing something? Using MT version.

I don't think it was was ever functional.  HUD brightness, yes, but not the pitch ladder brightness knob.

Oh okay. Well, hopefully it will in the near future. Thanks!
