Tailwind landing
-
@MRO:
Not exactly…
A330 as civilian is 10kts tailwind, but as A330 MTTR is different? No.
A320/321Neo as a limit of 15kts tailwind for instance. It only depends on the aircraft.That why I said “usually”. … can be different of course.
were you in CGN back in 2002/3? I was there on several exchanges… with Coca/Wroby/Yuri.
Yup.

Yup.
Miss those days, flying a “little bit low” over Fort Boyard!!

I know Kunsan prefers to operate 36, to the point of accepting tailwinds to a certain degree. I forget whether its a 10 knot or 15 knot tailwind component, before they switch to 18?
Usually, ATC’s allow up to 5, max 10 tailwinds. I don’t remember one which allow more than 10.

Would be nice if BMS ATC would operates a bit more tolerances on that aspect. I’ve seen weird situation with active runway changing because of a full cross situation and the wind slightly shifting from one side to the other. It created havoc on airport operations but happens in real ops as well Anyway What we have is already excellent. There is always room for more improvement
It’s easily avoided in BMS, but some instances using real weather created the above …

What would be your idea?
Currently, if I am not wrong, runway switches when head component goes above 10Kts tail.
What the logic should be, and how it would be dealt IRL? (keep in mind we have to deal with no brain robots … so all cases has to be taken in account and coded)What I think about:
Keeping the same runway active whatever the tails wind as long as we have a/c in the queue?
Closing the Airport and make flight diverting awaiting for less wind/or more established direction … ? , including departures … should they wait? Mission cancel? … should we cheat on the weather and prevent wind change during departing and recovery ops?I do not know what could be done (?) … and if it is possible (it could not be possible without beaking all the queue or delaying too much a/c on departure / recovery => Push time, remaining fuel …)

What is done in reality is that criteria for switching runway A to runway B and criteria for switching runway B to runway A aren’t the same. There is overlap so minor fluctuations don’t have the selection rapidly change. Plus they don’t sample the weather too often.

The decision to switch runways should actually be made on crosswind component, and have nothing to do with any tailwind. Once the crosswind component goes out of limits then the runway should be switched (or the PIC will divert) - depending on the field that may be as simple as swapping ends, or if there are more choices available it may be another runway entirely. In my experience if the field cannot provide a runway with the crosswind component within in limits for the aircraft operating at that field, the field will close. Forex - at the field I operate from we have surface wind limits because we had a guy killed post ejection by being drug across the ground on his parachute…hit his head on a rock and broke his neck. When the winds are up this high we close the field to departure and recover home-based jets only, but we also have three (six…) runways available to accommodate.
Only caveat to the above is how long the runway is - the runway available and being able to stop before the end is the real factor (and this also includes any arresting gear engagement considerations at both ends), outside of book limits…and that I’m speaking from a Navy perspective as far as fighters go. USN guys don’t land downwind…because you can turn the ship. Now you’ve got me wanting to check the book…as I’ve never even heard of such being considered in Navy ops I’ve observed.

… IIRC (really not sure about it) in-game, if Xwind > 25-30Kts, airfield is closed.

That certainly sounds reasonable, Dee-Jay…I’ve personally made a parachute landing with surface winds in excess of 40 Kts and believe me…it is NOT a “pleasant” experience.

Peacetime rules here, if Wv>35kts => no flight.
