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 55000ft....wtf ??? 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 airspace....is 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 ?
Thanks
