Please make the HUD in the aircraft displayed like those IRL, i.e. collimated.
-Firstly, I’m talking about the Head-Up Display system IN the cockpit, such as the HGS in the CRJ, or any HUD can be found in a modern fighter. NONE of them is correctly displayed right now. what I’m NOT talking about is the “HUD” gauges that displaying flight parameters such as airspeed, alt, etc for you when you are in the external view.
-Currently, it seems NONE of the HUD systems of any aircraft is correctly displayed: The HUD symbology/imagery is fixed on the combiner(that piece of glass in front of the pilot)plate which shouldn’t be.
-Parallax-free means no matter how your head(POV) moves, the HUD symbology/imagery appears as if it has been pinned on a fixed position in the 3D space somewhere beyond the combiner, instead of being pinned on a 2D plate i.e. the combiner. These videos below are perhaps better explanations:
Also, please check out this better explanation from a Naval Flight Officer, Mr. TinManNFO. As English is not my first language, mine might be somewhat unclear or confused.
(Also a gif from a WWII reflector gunsight(similar to what a real HUD should be) from wiki showing what parallax-free is, “The dot remains on the target even though the viewer’s head is moved side to side”:
)Think about gun sights. Assuming you’ve nailed the gunsight on the target, then moves your head out of the correct line of sight while the gun itself remains unmoved at all. Now you will see the crosshair “drift” away from the target in the opposite direction of your head’s movement despite the gun is actually still pointed to the target correctly. This is the parallax error. Reflector sights used by fighter plane since the 1930s is similarly parallax-free like the HUDs, means the crosshair will always represent the where the bullet will be impacted at regardless the head’s position(*assuming the gravity, wind, relative movement, etc are ignored of course). Why do we need it to be parallax-free? Of course it because the real one is! When you’d like to put the flight path marker/velocity vector on a point and get there, or using it in conjunction with the pitch angle marker to maintain the correct glide angle, you don’t want it to be aimed at the wrong place because you moved your head or you were not in the right line of sight when you took the aim.
-Collimated means the focal point of the HUD imagery is perceived to be at infinity even though the glass is just in front of you. This is not a big issue for now until once we get varifocal VR headsets, however, you may find many people using the word “collimated” to refer to the parallax-free effect.
-In the “edit:” part of this thread below you can find some “side-by-side comparison” videos and screenshots regarding how the current (3rd parties’) HUD is wrong.

Also, I forgot to mention in the original post that the brightness/readability seems to be very poor in the MSFS2020 T-45C.
-I don’t have the Premium Deluxe edition but according to the videos I found on youtube, I believe the default 787 is currently correctly made (at least kind of correct? It does feel weird in some angle.*updates: more information and discussion can be found in the replies).
Here are the videos aforementioned:
-According to this: MSFS cockpit HUD modeled yet? - #3 by ShinobiShadow
, it is the matter of giving the 3rd party devs access to the POV data. This to be honest is not an advanced feature at all, it is the basics as many others are, yet still missing as many others are. FSX, P3D, XPL, DCS, even ArmA, as well as a newly released arcade plane racing VR game has it! Some converted FSX plane can use a “workaround(it seems the way how FSX actually handle it)” to make it happen by putting the HUD imagery at a position somewhere beyond the combiner, however, the imagery can be viewed from outside as well, instead of viewing through the combiner.
-Even the so-called closed partner Aerosoft can’t get it for their CRJ. What about the upcoming PMDG 737NG3, QW787, and potentially the Majestic Dash 8 Q400 and even FSLabs buses? Not to mention T-45 F-15…and other modern military aircraft modules.
-This should be a priority because it literally comes right in front of your face. Unfortunately, I didn’t even saw a vote about it unless I’ve missed something.
-Sorry for being a little bit impatient. I really hope this groundbreaking new generation platform to be professional. It is the fresh air that could blow away the decades-long staleness of (civil) flight-sim. I really don’t want it to end up like a mid-core sightseeing simulator.
Please Asobo. Thank you.
