Del Prado I am really happy for your input here.
These would work on your side if implemented - although not realistic. Just a thinking exercise.
- move the limiting point further, 4.5D
- add a message to ATIS at peak times: "
High flow rate. Keep assigned speeds strictly on final, lest wing-tip clearance is not assured." The second part is already on the tape at Heathrow
- if somebody violates by more than 1,5NM, take them out of the sequence. Serious, twice in a single month and you will NEVER have that airline in your stats again.
For the small Airbuses, there is an issue. Strict adherence to all historical 1000' criteria and LP/LD + fuel-saving (ehm, carbon lean, green ops) approach is not compatible with the 4,0D/160. Something has to give. If the incumbents devised a clever way that works on a large scale basis for them, it must be possible to propagate that to other operators. Infrequent visitors maybe not too much.
Did you know, that apart from UK and FRA and AMS (cannot really recall anywhere else), the 180 knots restriction is never amended or lifted - unless separation critical? That pilots as a daily operating practice need to second-guess "how far do you want that"?
