Separation behind A340 on departure for similar routes
So.........
Is there a case for dropping the A342/3 down a speed group?
Or provide 3 minutes separation behind for a/c on similar routes instead of 2?

On departure an A340/200 flies very slowly. The speed will be in the order of 180 kts for about 20 miles plus (in my experience). Please correct me if I am wrong. TC tried to have the aircraft put into a lower speed group for years, due to so many catch ups. All the time it was resisted by Heathrow, I believe beacasue it might have reduced runway capacity.
I would still like to see the aircraft in a lower speed group, however, we don't see so many now, so it it not such a big problem.

Just like to point out that the resistance was from Heathrow Airport and airlines and not ATC.
Makes no difference to us what speed group it is in and it would help our chums at TC who have to deal with the darned things every day.

Never mind dropping A340s down a group, can't we drop the A380 into a big bucket somewhere far, far away and forget about it?
The now 20NM gap behind when landing at LHR due ILS issues is just taking the p1ss! If this isn't sorted before more of them start arriving at busier times it's going to lose far more pax and cause more delay than the few extra it carries might ever justify.
It'll be fun if and when the first one calls PAN on a go-around and wants to divert to LGW as well... "your PAN is acknowledged, expect a thirty minute delay whilst we find some extra firemen"
Fingers crossed it's not LVPs either or it will really stuff up everyone else at LGW nicely.

SIA will commence a second daily A380 flight into EGLL from July 16th (4 days a week to start off with) so the 20nm spacing may then become more of an issue. UAE commence daily operations on UAE1/2 in December too. But of course the A380 will not have any major impact on airfield operations...

The 20 mile requirement might not be needed, but until the investigation is complete then we're erring on the side of being safe.
What will happen if the requirement stays? A380 landing fee tripled?

Surely the complaints only levitate to the A342/A343 with those amiable yet undoubtedly small CFM-565Cs...
How does an A345 or an A346 compare in departure performance with those huge Rolls-Royce Trent 500s?
