Hi Lee Perhaps you should set the start time to 6:00 am, 1 February 2009, to compensate for the the daylight savings time in Eastern Australia. I suspect that your computer is not adjusting for daylight savings in West Sussex as you would not be on daylight savings. In real time the sun will not rise until 6:41 am in Darwin. So, I am not surprised to hear that you are trying to find the destination airport before sunrise as you were probably over the field in darkness. For a comparison, when setting my DC-3 for the flight from YPDN to YOEN, it took me 17 minutes of pre-flight settings and checking before I was ready to roll out of Darwin. So, my local time had advanced to 0517 and GMT to 2117. Yes I live in Australia (145 deg east of GMT) with Eastern Standard Time set to adjust automatically on my computer. I do not understand why FS9 is reporting a difference of 9 hrs between local time and GMT when it should be a difference of 9.5 hrs. My FS9 is set to display Flight Time. My flight from Darwin to Oenpelli was conducted in a dawn light with very clear visibility of terrain and the destination airport. The sun rose dramatically during my flight because I left Darwin at 6:17 am real time and arrived 62 minutes later at 7:19 am real time. The sun at this time had an altitude of 8 deg 23 minutes above the horizon (SkyMap Pro). Hope this helps. Regards, Les

Les,
Thanks for your input.
I believe you are correct in accounting for the anomaly. We are not on Daylight Saving time anymore now, as we have reverted to GMT now that our Winter is upon us. Of course it is heading towards summer for you guys and so DST is active in parts of Australia, I believe.
FS has always had a time issue, reporting totally incorrect times for certain areas of the world. This is a known bug in all versions of FS (which has resulted in Pete Dowson introducing the correction algorithem into FSUIPC when he programmed it). It has also led to pieces of software like FSRealTime appearing and attempting to compensate for DST in various parts of the world. FSRealTime does a pretty good job - except that i cannot have it running all the time on my FS setup. I might just try it now though ....
I took off from Darwin at 05:36 on my last test flight and arrived over Oenpilli in a dawn that was light enough to see the field and make the landing so I'm satisfied and happy! I also did a rather splendid flight into Garden Point which was really close to my allowed time.
So things are getting better!
Thanks for your comments.
regards,
Lee

Fellow pilots, As Andrew alluded to in his comment about Just Flights' 'Airliner Pilot' there is a known problem in FS9 with GMT offsets and Daylight Saving/Summer time adjustments that specifically affects Australia and in particular the Northern Territory and Western Australia where GAAR 2009 is being flown. The only fix it is to override the FS9 times by manually adjusting the Local time in the Alt/World/Time & Season in MSFS/FS9 or go into the GM Offsets File in the config file.

I found the start of this leg had the sun rising and clear of the horizon by the time I turned east, so no problems finding Oenpelli (there is a little lake just SW of YOEN which makes a good VRP). Will switch to an hour earlier for my other a/c.
