Thanks. My interest is professional, in researching the issues that need to be considered when undertaking such a procedure design. There is currently such research and trialling being undertaken in Oz, US and shortly in various European destinations as well. Maybe other places are also undertaking such effort, which if so, sharing of information/experiences will be of a distinct advantage. As LHR currently seem to be the only "regular" user at this end, there would seem to be scope for a wider application, especially during hours of low demand, such as AMS provide. So, any answers to the specifics raised will help in building the knowledge base, and yield something that works, and can be used at a wider cross section of aerodromes.
