Why do Heavies ask for wind checks?

[FatesPilot]

Flying out of SFO, I constantly hear the majors asking for wind checks on final. This seems to annoy the tower at times.

I'm curious as to why they ask for the specific wind?

Not to be a smart a$$, but wind affects all planes.. not just the light ones....

Some of the SFO controllers are easily annoyed.

How longs the final today???

Can I get a sequence?

Wind check???

'Cuz there's no windsock.

Dumb question? Not really. While larger airplanes are less affected by wind than smaller airplanes they are also less manueverable so you have to anticipate your corrections for wind as soon as possible. Take in consideration higher approach speeds for larger aircraft that are near their max langing weights and it can get pretty exciting if the wind is doing something that wasn't expected.

You should try flying a BOX with a 15 or 20 kt direct crosswind. Talk about a challenge..Anyone who has flown the SD3 can second that. It's like having a barn door strapped to the side of your plane.

When your rudder is as tall as a five story building youll ask for one too.

Because we have a direct wind direction/speed readout in the cockpit, we know what the winds are for where we are. What we want to know is how much it might change between that point and the ground. Provides early heads up for windshear, etc. Remember, that much mass doesn't change direction in an instant, so we can't recover from wind changes like a light airplane can.

id like to run a follow-up question in that same vein. what speed does a typical heavy rotate/touchdown at? assuming normal conditions and weight...just curious
