Altimeter and pressure vs. altitude

[Gierasimov]

Hi. I need your help, please. Could somebody explain to me what I need to do to be able to fly formation with AI on the same FL please?

 

So far I tried various settings and I can't work out what is wrong - I set QNH in Mission Editor to 29.92 in Hg.

In the Hog I set Altimeter barometric pressure to 29.92, now both HUD and ALT show the same altitude MSL. However, on the F10 map, I can see the altitude is different - see screenshots.

 

My issue - KC135 FL160 (in ME set to 16001ft) in F-10 map visible as 16000ft, however, if I set myself right behind it at 16001ft in ME and launch mission, my ALT readings are different with said QNH.

HUD: ALT:

I made a quick test and re-read what Frederf had given of information a while back to me regarding altimeter.

 

It appears that the altitude set in ME is Geometric altitude/GPS altitude. The altitude on your HUD and altimeter is barometric altitude.

 

If you set your Aux. Avionics Panel Page knob to POSITION you can see the Geometric/GPS altitude.

 

Tanker @16000ft according to ME

Seen in bar of the screen

 

A-10 at tanker level

HUD and altimeter shows 15700ft but G ALT shows 16005ft

 

Same A-10C from F2 view

 

For more in depth information please check out the explanations by Frederf in this thread; https://forums.eagle.ru/showthread.php?t=189765

 

 

Cheers
