-----------------------------------
I did a night flight to the airport above.
It was pitch dark outside and on my decent I plowed into a mountain.
I was using a FS Nav, programmed flight.
The next day I made the flight in daylight and sure enough on my decent there was a mountain in my path.
I shut the auto pilot off and cleared the mountain and landed.
Question is how could you avoid this while flying at night when not using ATC As a glide ?
I have been flying FS Nsv for several years and have noticed on several flights I had to ovoid this problem.
Comments please .

I think it's a problem in FsNav and FsP can't solve the problem.

Didn't your copilot shout to pull up? or the GWPS?

moved to general as said above, its not fsp related, would happen even without using fsp

MAybe you could check your route with a little utility (sorry, can´t remember the name) that shows your path in Google Earth,....

This probably isn't the fault of fsnav either. Checking your flightpath as mentioned above would probably alleviate this problem in the
future, especially when arriving in a mountainous area. Though after further thought FSnav may not have elevations so I'd use it in
conjuction with either a map with elevations or even within FS flightplanner to ensure your approach avoids major obstructions.
