IO540.......However, a couple of fatties in a spamcan....
What a wonderful euphemism...
Even at my weight I was rarely asked by my instructors to do a weight and balance check,even when one of them was a wee "fattie".
I always did one however, even if it was at the irritation of an enthusiastic FI wanting to get going as soon as possible in order to return for his morning bacon rolls.
And as pointed out by IO, the smaller the craft the less you have to play with.....
