Barometric Altitude showing negative in Syria Map

[honeycool75]

In the Syria map only, I'm getting -ve altitude after proper INS alignment. I've double-checked in other maps, this problem doesn't exists anywhere else.

 

Can someone help to cconfirm whether this is already a known issue?

There are some areas in Syria that are below sea level a quick google search turned up. Maybe that's all there is to it.

Does INS alignment set the QNH? I thought that needed to be set manually.

Set Manually and the Altimeter needs to be set to Electric (unless that bug got fixed)

How do you set the altimeter to electric ?

make sure you set your QFE right

a lot of airfields in Syria are 2000-3000ft above sea level, check your starting altitude in the kneeboard and rotate the QFE knob (under barometric altimeter gauge) so the altitude matches the one in the kneeboard

I always thought INS alignment does that... Ok, I will try this. Tx.

nah, INS alignment has nothing to do with this

if you want to check on other maps - try Shiraz or Nalchik - these are airfields with high elevation above MSL

FWIW - Plenty of times IRL I've gone into a plane and initially it shows the altitude below sea level (at an airfield that is above sea level) - such as if the plane was last used during a low pressure cycle, and then I fly it a few days later when a high is over the top. :)

Using the little flipper that can go between Electric and Pneumatic

AFAIK there is not "little flipper" for the altimeter in the mirage, what switch are you talking about ?
