On the subject of x-wind landings quickly, I agree with poetpilot. I take in mind where the wind is coming from and it's strength and visualise it in my mind.
As a low hour PPL (56hr) i'd like to think i'm responsible enough not to go up there when the wind is very strong and likely to be outside limits until i've gained more experience. Like people keep saying, the PPL is a licence to learn. It's dangerous to jump in with great size 9's straight away. Many a cocky driver has come unstuck soon after passing their test and these ain't cars we play with - they're potentially far more threatening to our health.
