Mirage F1 HUD Misalignment Bug

[Ski11B]

So, first off, the Mirage is such an incredible mod. I love it, but for the life of me I cannot align the HUD nor the ADI or backup ADI. Please believe me when I say I've researched the hell out of this on the interwebs and have started up the jet, what seems like 10 different ways, according to reddit posts. It is so incredibly hard to fly the jet straight without constantly quickly gaining or losing altitude. The track I've attached is me starting the alignment with ground power only. But it doesn't matter how I align it because it turns out the same every time. Thank you in advance.

I don't understand, there is no HUD in the current versions available of the Mirage F1.

Loukins this is not helpful. Yes , the manual may still call  it a "sight", but for all intents and purposes the Mirage F1 CE,BE,EE already have a HUD.

I mean, seriously, what more would you need to make it a "HUD"?  It has a flight path vector, its has a target designator box during radar lock,it even has steering cues to the target,  it has a pitch ladder, it has an aircraft symbol.

It is definitely not a simple optical sight , like those found in the 50s vintage aircraft, as F-86, Mig-15, or even F-4 for that matter.

 

Technically it is a HUD. In the end, a HUD is also an optical sight in the purest sense of the word.

Ski11B, 

for some weird reason I cannot open your track file. Can you be more specific what your problem is? Which variant of the F1 do you have the problem with?

What do you mean by exactly  "align the HUD or the ADI"? Do you have problems aligning the gyroscopic system? Or do you want to align the HUD with the actual horizon?

The HUD horizone line will only match the real horizon outside at low altitudes. The manual also says so:

Actual horizon: this symbol represents the actual horizon, which will coincide with the Earth’s horizon at sea level. At high altitudes the actual horizon will be much higher than the Earth’s horizon, due to the curvature of the Earth.

You can always use autostart function , that should ensure  a technically correct gyroscopic system alignment and eliminate any user error. Just wait for the "autostart complete" message and you re good to go?

Or is your question about flying straight and level at a constant altitude? This is best done by setting the correct pitch attitude and power and then trim as necessary.

Bro, it's not a HUD, it doesn't have a FPAS, it just shows your Vertical speed in the sight, also it's a sight because all the stuff you see are mechanical and cannot be changed. Mirage F1CE, BE, EE don't have a HUD. 

To have a HUD it would need a somewhat of a Navigation system (yes the EE does have one, but it's pretty barebone and is very close to the Super Etendard one.) and a proper HUD with digital input/output to properly customise and have all the info of a HUD. (Also HUD means, Heads up DISPLAY and there is no display in those version except the cathodic monitor of the radar)

Yes it's not one from the 40s-50s in what you can see in early Cold War aircrafts, but one of the latest Sight with good engineering behind.

A HUD is not a optical sight because it uses a DISPLAY to show informations.

There is no calculated FPAS or anything, it's a sight with mechanical sight you can move. The sight is linked to your GM switch.

But it shows a lot more than vertical speed? I mean the main point is you're being very disingenuous when someone references the HUD on the F1 and you're like "what HUD? The F1 doesn't have one, I have no idea what you're talking about". Because obviously anyone can deduce what component of the aircraft someone is talking about when they're referring to the HUD in an aircraft that has a "sight" that includes a ton of traditional HUD info.

But even beyond that, the HUD in the F1 includes and is not limited to:

• Altitude
• Heading
• Pitch ladder
• Bank indicator
• Radar range
• Time till missile impact
• Computer calculated target interception angle
• Gunsight and radar assisted pipper

The point of a HUD is a display that lets you have your head "up" instead of "down", and all of this information on the sight was previously relegated to the instrument panel, therefore introducing an improvement on letting your fly with your head "up". Just because the means of projecting the image is optical instead of digital doesn't change the entire function of the display.

I'm sorry but even the maker of the aircraft and the maker of the Sight is calling it a SIGHT. You can contact Dassault if you want them to fix that. And that you know better than them.

And yes it's different.

You still didn’t really get the main point, did you now?

Well nevermind, you‘re way too busy being self-opinionated anyway.

Bro, stop being trigged because you were wrong one time, it's fine everyone make mistakes me included.

Did anyone actually bother to watch OP's track and understood the problem? I'm away so I couldn't myself.

Of course les Français would call a "HUD" something else. Affichage tête haute Sight sounds better.

In france ATH (Affichage Tête Haute) is litteraly the translation of HUD

I think he is not letting the ADI and the Backup adi to align which takes time, or he thinks that the F1 has a HUD just like the 2000C for exemple that's all I can understand, because he said 

"But it doesn't matter how I align it because it turns out the same every time. Thank you in advance."

Yeah, I get that. I haven't cold started the F1 for a while, but I can't remember ever having an issue.

In french manuals, it is called:

- Mirage F1C/B: Viseur (sight).

- Mirage F1CR/CT: Collimateur Tête Haute (Head Up Collimator) since it is not certified as primary instrument for flight.

- Mirage 2000: Visualisation Tête Haute (Head Up Display) since it is certified as primary instrument for flight.
