Could be 380 or could be Meters. 30800 is about 9,500 Meters.

I'm hoping it's a typo.  Although something very odd happened to me the other day in PFPX.  Planning a Dash 8 flight and the planned OPT gave me FL246!  Uh ok. What the...  Obviously just flew the correct altitude (FL250) but that was strange.  I haven't had time to look into the why.  Typically PFPX gives me normal altitudes.  Not always the best for the distance (e.g. Short routes/too high) but rounded off properly.

Check your PFPX step climb size and make sure it's set to 2000 or something else.  Problem might be lurking there.

Hi Guys
Sorry for the delay.While away I decided to make a fresh start and do a clean install of PR3D and both the PMDG 777 base pack the expansion pack,also the B747, along with PFPX. I am pleased to report everything is running fine.I managed to fly both the 777-300 and 747 tutorial flights with no problems,also made a flight from EGll- Heathrow to KSFO-San Francisco using a PFPX flight plan again with no problems. So I reakon I had a glitch on my machine somewhere. Thanks to you all for your guidence and support.

Best Regards
Alan-UK.

I typically turn the step climb off, even since most of my 744 trips are short hauls.  It hasn't happened since then but I'll keep an eye on it. Strange.
