RWY use at EGLL
What are the rules for when to use RWY 27L & R for arrivals and departures when on Westerlies?
Seems to be a trend that (in this particular scenario) RWY27L will be used for arrivals up until 1500L at which point the RWYs will switch. I believe this alternates each week.
My question is, if the 09s had to be used mid-week say, for a day, until Westerly ops were current again (say the following day) would the RWY use of the 27s stay the same for what they would have been that week?
What is the alternation this week?
I'm thinking it might all be dependant upon current weather, but I was wondering if there was a general rule of alternation schedules that LL will use if conditions permit it when on Westerlies.
