Strange thing happened (once)

[Alfredson007]

I tried to check my pitot heat, but despite having pitot heat on for 30secs or so, it was still cold... i checked the maintenance hanger and it said all OK... so i started to fire up the engine... after the startup the avionics didn't go ON at all, and VAC lights stayed on and VAC gauges said no vacuum is present. Then i noticed my cabin had gone VERY foggy for the first time, eventhough the weather was the same as usual (my default), and it never hasn't fogged up earlier, eventhough i tend to forget the ventilation fans almost everytime.... and about the VAC, the hangar still told me all ok. So i shutdown, reload, and all worked fine.....

Just sharing....

Hello,

this sounds like a slightly sketchy load of the flight, and can happen with complex add ons. To help with these issues it is recommended by many to first load a default aircraft and then switch aircraft to the aircraft you wish to fly.

thanks,
