I've flown a 172 more loaded that!

I've flown one on a ferry that was probably about 300 or 400 lbs
overweight, but off very long runways and in a quite cold region. No
problem, but I wouldn't do it as routine and I wouldn't do it if
performance was an issue. A couple of pounds overweight is one thing,
but it doesn't take much to reach a point where the airplane won't go up
at all, particularly if it's a relatively low powered aircraft like a
172 in the first place. The degradation is not linear, so if there's a
100 FPM loss with a 100lb overload, it does not mean that there will be
a 200 lb loss with a 200 lb overload. Obvious, I know, but it's
something often forgotten when wishful thinking takes the place of a
rational approach to the problem.
