Thanks for all of the replies..rest assured, I understand the system works great for everyone, I am just trying to understand what I have been told about why.
There is no difficulty at all in producing a single approach sequence from "multi-variant" sources.
Understood, I am familiar with multi-variant stacks...my query was based on having separate hold patterns with heavies in one, and light/mediums in another, and how that would blend. From what everyone is stating, it appears that the hold patterns at KK are not segregated by weights.
As a pilot, although not Gatwick based, I can assure you KK (LGW) is a very, slick, efficient and professional service.
Concur..with all respect for the system and the people behind making it work.
Not sure either where you are located, or indeed what the motivation is behind your query of UK wake vortex seperation standards?
In the light of PBN/RNP, with the potential for the ac to be on the same horizontal and vertical profiles, so there is alot of criteria and regulatory discussions about separation spacing.
As an example, currently, heavies keep low on the GP, and others go a little high when following, and while this is not necessarily formulated in regulations, it is practical in operations.
Everyone, my query is much more in understanding how the exemplary operations at Gatwick work, from people in the system, rather than from a regulators perspective.
(for reference, I am based in the PacNW...)
