Windsheer

I have just flew from KJFK to KACY using real world weather. On the glidescope I had winds at about 32kts on my 5 oclock. Alarms started going off saying "Wind Sheer". ive never heard this one before. Is it part of fspassengers or will it be part of my a/c?

I made a very hard landing, about 700fpm. Would aircraft in the real world attempt to land in those conditions?

Thanks Very Happy

From where did you get this report? Shocked I like it Thumbs Up!

I have never heard such a warning from FSPax. Umm... Maybe its your craft sound's packet.

Those winds are fairly extreme. A real aircraft would not land in those winds with a quartering tailwind. You should have used runway 31. The alarm you heard was from the GPWS in your aircraft.

Looks like you are using real world weather. Real world you would probably get RW31 at KACY and it would give you no problems (crosswind limits).
Windshear is however a major problem and has lead to many real world disasters.

While approaching Dallas runway 17L in rain and thunderstorm, the TriStar entered a microburst. At 6300 feet short of the runway threshold the aircraft struck a car on a highway, collided with two water tanks, broke up and burst into flames.

PROBABLE CAUSE: "The flight crew's decision to initiate and continue the approach into a cumulonimbus cloud which they observed to contain visible lightning; the lack of specific guidelines, procedures and training for avoiding and escaping from low-level windshear; and the lack of definitive, real-time windshear hazard information. This resulted in the aircraft's encounter at low altitude with a microburst-induced, severe windshear from a rapidly developing thunderstorm located on the final approach course."

A lot has been done since then and my suggestion is to firewall it if you hear windshear! Hold and approach when the storm has passed.

Some good info as always there, thanks all!!!

I got the weather from http://weather.noaa.gov/weather/current/KACY.html

I believe there is a feed similar to a RSS feed that sites like this use. If I get chance ill knock together a PHP script that will find the weather for any airport using this.

I wonder if that's what I had happen to me just a while ago.

I was flying from Anchorage, Alaska to Sea-tac in a 737-300. Everything was good until the landing. About 50 feet above the ground we started getting some nasty turbulence. The plane actually bounced off the runway and sustained some major damage to the landing gears.
