Also, if this is to work, you would need to have the GPS
powered up and running at the moment of the failure. It's
not like you'd be able to hold wings level while taking three
minutes for the GPS to power up and acquire satellites....

Another option would be the old whiskey compass, as long as you can
get to an east or west heading.


All the best,
