Windy Landings: What Are The Restrictions?

Fri May 25, 2001 5:36 pm

When does it become TOO windy to allow for a safe landing? How many knots/MPH?

Depends on the aircraft and the direction of the wind.
It might also be more risky to stay up than to attempt a landing at some point (say, fuel almost gone, engine failure etc.).

It depends on the wind direction/relative to the runway and the aircraft.

The size of the aircraft and the weight

And the limits of the aircraft.

For example, When I worked for Reeve we frequently would conduct flight operations in 60 knots of wind or greater with the B-727 aircraft

No, Interesting was the time I was in the back of a Reeve 727-22C landing over the dike at Adak, Alaska with a 45 knot tailwind.

Max permissable x-wind for SIA B744 TO is reported to be 30 knots.

L-188, In my short time flying into PADK, we once took 25G30 on the wingtip in order to avoid circling when the weather was just below circling minimums. I have a healthy respect for some of the things the Reeves guys have done out there. Unalakleet and St. Marys always seemed to have crosswinds. 4 AM mail flights in the winter usually meant approaches and a direct crosswind every time, usually 20+ knots.

Oh yeah, I remember Dutch Harbor a week or two ago had the following weather:

05017G54KT 040V140 1SM SN BR OVC001 PKWND 100086/20 [we cancelled that particular day]

A 45 knot TAILWIND? Are you sure?

The normal tailwind limit is 10 kts.

Yup 45kts.....

Heard it from the guy riding in the jumpseat and we where noticably faster on the landing. It was enough to get my attention and I had been working for them for about two years then.

That and I ended having to load the same flight out there and I would say it was blowing that hard too.

Pilot I work with took this shot. In case anybody want's to know what the Dutch Harbor Airport looks like. That was the METAR that PW 4804 put up earlier.

A 45 kt tailwind?? are you nuts? AFAIK, the max cert limit allowed is a 10 kt tail for commercial. Crosswind winds vary depending on contitions and airplanes. I once read that when flight testing the 747, boeing couldn't find a crosswind strong enough to move the plane off course. I don;t know the accuracy of that though.

You guys in Alaska must be crazy... i wanna come ride with you. Later
