I recently conducted a flight from Atlanta to Dallas Fort-Worth. During the flight, I requested to step from my original cruise altitude of FL350 to FL390. The request was granted, however, I later noticed I could no longer request DIRECT to any navaid in my flight plan (i.e. the menu option was no longer available to me). The DIRECT Navaid option was available from the menu earlier in the flight, but disappeared permanently after the step climb. I can't say if the two events are related, but I am curious as to what conditions might arise that would prevent this option from being made available to me while enroute.Thanks,J

i've never seen the direct navaid menu item go away, but then again, i wasn't looking for it.see if you can reproduce it.fly it again. before you request higher, save a dat file.then request higher, climb, then look to see if you can request direct.if not, send me the .dat, ,pln, .flt, and .wx>>>Update<<
