Thank you for all your answers. Yea, never got shown refuelling, but will ask when I go back to the airfield (hopefully next week some time).
If there is an Air/Ground service - ie Placename Info - they can't tell you what to do, so start -up would be at your leisure.
If there is a FISO - ie Placename Radio - then they can tell you what do do on the ground, except when on the runway. So you might not be able to start up without their permission.
And, of course, a full ATC may even have a dedicated Ground frequency.
I thought this was the case, but wanted to confirm.
This is not a practical problem for those many of us who can't afford a rental long enough away from home base to use up a tank full of fuel!
I won't be away long enough to use a full tank, however, a 2.5 hour return flight (requiring 55 l of fuel plus 15 l reserve), with a PIC weighing 75kg and a rather portly passenger in a Robin HR200 means I won't be able to put the full amount of required fuel in on departure, I'll have to do it in 2 sections.
Thank you all
