Yeah a lot of these diversions if I remember rightly were due to the -800 in BY use being unable to accept any tailwind component on 32 for aCAT3. Seems the Jet2 -300s don't suffer from this and neither do RYRs -200s. So maybe it's an -800 thing! I'd even go as far as to say it's operational because the 800 needs more runway for a CAT3 than LBA currently has due to it's CAA enforced displaced threshold.
Don't flame me it's just my thoughts, put me right if you know better.
