Filing Flight Plan
Hi all,
Got into a discussion yesterday about the use of lat/longs for fixes when filing an IFR flight plan. I seem to remember that, while a radial/DME or fix name is MUCH preferred, it is also possible to identify a point using a lat/long on your flight plan in a radar environment.
The regs seem a little vague on the subject - I found a reference stating this was acceptable for RNAV aircraft filing great circle routes above FL390, but I really thought this was acceptable in other situations as well.
So, after a breif regs search - I caved and used the message boards.
Can anyone confirm or deny if it is legal to define a point on an FAA flightplan using lat/longs? (I mean legal, here. I know it's not a good idea, if you have another way of identifying a fix, and I know why it's not a good idea - I'm just wondering if it is in fact legal to do so on a typical flight...)
Thanks!
Jeff
edit: the reference I've found so far is section 5-1-7, dealing with flight plans. i'm almost certain there is another reference I'm missing, though....
