Holy #%&*$# moments during a landing at EGTE (R26) with a 45+ Knot crosswind and wind shear. Crab-it-like-it's-hot!

Now that's a cool landing. Is that Xplane or FSX? I liked both the plane and the scenery.

Love the radio chatter and sound effects. If I could add one thing to FSX/Xplane it'd be radio chatter and sound effects from passengers.

Nice video. One observation, which is more of a limitation of the sim than anything else, is that with that kind of wind, there is no way that the approach would be that smooth. You would be making constant corrections to stay on course and on the glideslope because the wind is ever changing. IRL I would just go somewhere else where the wind was better aligned with the runway wink .

FSX.

The ATC chatter is in the sim/addon. I modded it myself using UK specific ATC calls and then ran it through Audacity. As for the passenger sound effects, Merry Christmas. Obviously you need AXE.

So on the topic of hilly runways, is there a reason engineers do this or is it just to be cheap? Why would you not flatten out the ground before laying the tarmac down.

They're sloped or concave to provide for drainage.

Interesting paint scheme, I thought Flybe didn't do airbus and only had embraers.

Good landing anyway as 45 knots is above the scarebus max demonstrated xwind thumbsup

Agree with Paul that it would be awesome if ground terrain and wind would cause some sort of turbulence.

One question, I could hear the windshear call. Was that the actual plane or was that background chatter?

I'm sure that none of those videos were with 45 knots of crosswind. Most airplanes I have flown have a "max demonstrated" crosswind of about 25 knots. Landing in any more than that puts you in test-pilot territory (and open to a negligence lawsuit if you bend metal or hurt someone).

The most severe was Dusseldorf with gusts between 24-37.

The A320 has a MCW of 30kts (35+ with STBS), 737-800 at max of 34kts, 777 a max of 40kts.

WGL was between 28-32 with gusts up to 45+. I thought I was doing pretty well until right before TD when a MB/wind-shear nearly slammed me into the tarmac. Granted, it's not a exact simulation of those effects, but REX and the core FSX weather engine do they best they can given programing limitations.

LOL, well I'm glad I am not expected to land in crosswinds like that.

Having landed in 15knot crosswinds with 20knot gusts in real life, I would agree.

Noway would I want to touch 25-30knot crosswinds. Most airplanes don't actually have a "rating" for what crosswinds they can land in aside from what's been demonstrated. It's up to the PIC. When I'm PIC, 15 knots is about what I feel comfortable with right now and if you think that's not a lot, you haven't flown in real life lol...

I did 3 landings first at Stafford, which is pretty wide open and a jet runway. Then went back to Potomac. Trying to fight those kinds of winds into a short field surrounded by trees would is extremely tough.

This is one place were sims just fall so short of showing you what it feels like in real life.

The A320 has demonstrated 33 knots with 38 knot gusts. That's a ton and probably a good bit more then most pilots would attempt. The airport might close the runway with those kinds of winds.

Keep in mind though that those numbers are visual landings. ILS landings have their own limits. I think the max crosswind for an A320 on a CatIII landing is 20 knots.

Hey Bonchie, what are you flying?

Having flown big and small, bigger tends to get beaten about less in turbulence. And given that any wind much over 20kts on the deck is likely to be at least a little turbulent, the big planes don't rock and roll quite as much in high winds regardless of their orientation. Also, the faster your approach speed, the less the crosswind component is going to affect your overall velocity vector. In fact, in some planes it was common to use less flaps in order to get your approach speed up in gusty conditions or in crosswinds. So, a 30 knot crosswind is going to affect a Cessna a a lot more than a 737.

As far as closing the airfield or diverting a flight for crosswinds, I can tell you that no commercial airfield is likely to close unless the winds were essentially above the max winds, cross or otherwise, for the most capable aircraft that flies into there. In most cases, the decision is left to the pilot/airline to dispatch into a field or not.

All wisdom aside, a max crosswind landing is generally required in the initial proficiency check for a pilot. As such, most air carriers, being in the business of getting customers/cargo to their destination, not in not getting their customers/cargo to their destination, will dispatch/file a flight to any field where it is legal for them to do so...all other factors being equal.

In fact, I recall being dispatched into a few situations where it was legal, but unlikely, that we would get in based on the presumption that the weather might not be as bad as forecast and that we could still divert to another company alternate in the event it was.

Counterintuitive from a safety perspective, I know...but entirely intuitive from a financial one. wink

Yeah, I fly 2 notches of flaps to the runway instead of 3 in the Cherokee when I'm in bad crosswinds.

Usually I'm 70mph (piper's don't measure it knots for whatever reason) over the threshold and declining from there but was closer to 80mph this time.

When I got back to Potomac after leaving Stafford, the winds were 18 knots and off about 50 degrees (outside the Cherokee's normal limits). That airport is in a valley and surrounded by trees. When you come in to runway 6 you come in over trees and houses so you get thrown around like crazy, not even counting the crosswind wind.

Sometimes crosswind landings are fun. That one wasn't lol.

My instructor was the co-pilot on the initial C-17 test flights. I can't remember exactly what he told me they demonstrated at but it was somewhere in the 30's.

LOL@ Detcord.

Don't consider yourself a violator yet. As the Max demonstrated Xwind of an aircraft is not an Flight Manual Limitation from the manufacturer, its the (max) xwind experienced in the certification process.

Airbus recommends operators not to exceed this value. So I think you get off.

But,

operators impose limitations and as you had Flybe colours. I am sure an operator would limit the max xwind for ops at or below the max demonstrated..... so unless you are the virtual operator owner of Flybe A320's on your computer I would expect a Sit down with the virtual base manager for a "tea without biscuits" chat.

So I guess you are screwed.

What scenery are you using? and its FSX right?
