The Germans had limited air time over England. The RAF had a lot of time on station. The Germans planned poorly on that one.

Luftwaffe fighters could remain over England for only about thirty minutes. The battle was already half lost for them.

And the RAF made very good use of the new technology of radar.

Yes, because of radar the British squadrons could stay on the ground until the Germans approached, which gave them even more of a time advantage.
