I was wondering as to whether or not there is a signifcant difference between selecting alternator on before start or alternator on after start in Piston Aircraft. I have flown now at four different flight school's and three of them we selected ALT on prior to start and one we selected ALT on as part of the after start checklist. Is there any significant impact on the electrical system assides from the obvious fact it will be slightly harder to start the aircraft with ALT on but re charging commences immediately after start.
Thanks Heaps....
