Wind issues in heavy jets
As a PPL, if the wind is strong there are occasions when I won't fly, even if it is straight down the runway, as I know it will be very bumpy with lots of windshear, and I don't like flying in it close to the ground.
As it's been pretty blowy recently, I was wondering if a similar scenario arises if you're flying a heavy jet, 747s and the like. Suppose for example the wind is down the runway, so there are no crosswind considerations - are there occasions when you wouldn't take off/make an approach because of the wind - if so, what things would influence your decision?
