HUD Altimeter

[bengo]

Hi,

I've noticed that the altimeter in the HUD doesn't update while in a bank. Is that expected behaviour ?

Kind regards

HUD altimeter* relies on the radio beam that is pointed down, so at high bank angles it would not process the data or even not receive it. Same way as the HUD speed indicator that relies on doppler system that is also pointed down.

* it is important that altitude must have a russian letter "р" that indicates feed from radioaltimeter. If there is no letter, it shows the barometric altitude, so there are no limits to the bank angle.
