  • Problem with altitude/altimeter

    Hey senior/student pilots

    I was flying an Emirates 773 flight from London to Dubai when I had experienced a strange thing...but let's start from begining.
    I was cruising at FL400. It was all cool My altimeter was set at 2992 for the whole time as told by the ATC. When I was getting closer to UAE ( about an hour away) I entered Iranian airspace and was told by Tehran's ATC that altimeter is still 2992. But after sometime altimeter in my plane wnet crazy and suddenyl jumped to ??? I pressed ctrl+z to check and it said that my altitude is still 40000ft. But then ATC is yelling to descened and maintain FL400. So I descend and as soon as I reach 40000 my altimeter changes from 2992 to something like 956 and shows that I am less than 10000ft above the ground. So I climb and again - 50000. And Iit goes like that until I live Iranian it a well know bug ? Does it happen in Iran only or some other parts of the world too ? And how can I avoid it ?

    Next time this occurs try pressing the B key. That should reset your altimeter back to the correct figure... in this case 2992.

    Hope that helps,

        Yeah you need to try and reset it manually. This has happened to me before.

          For a start you should be declaring Iranian Airspace a No fly zone maybe you were hit by a S.A.M !
