However….
Don't be too blasé about weight. I flew a PA 28 (or 32, can't remember) out of an airfield in France on a hot day with 4 people on board, full tanks etc. very much on the limit and it was very bad news.
Did get off in the length of the runway, luckily it was a commercial airport but rate of climb was horrible. Never did it again
It's very easy, especially when travelling, to just fill up at an airfield and go without doing all the sums. I learnt the hard way.
