As Whirligig mentioned, you are allowed to use the GPS on the diversion leg. You are only allowed to use it in "raw data mode" i.e. showing either Lat and Long or a range and bearing from a waypoint. Moving map displays and GoTo features are not allowed.
Dear God give me the strength to have it in my heart to forgive the idiots who sodomize the minds of the general pilot population with such darwinism thinking as the above.
How any mouth breathing morons ever got to be in a position to teach such rubbish is beyond my comprehension, to restrict pilots from using the most modern navigation aids such as GPS with not only three dimensional extremely accurate situational information but also a pictorial moving map presentation is mind boggling!!!.
I think that as a new years resolution I shall quit reading these aviation discussion forums so as not to become so depressed that I put my head in a gas oven and end it all.
