have been to forums in which continuious requests to do things for the purposes of separation have not gone down well. Especially as the pilot complying with the request never wanted separation in the first place.
If they didn't want separation are they prepared to erode against traffic that obviously does? If yes, then I refer the Rt Hon Gent to the answer I gave earlier - slack airmanship. These guys need educating and reminding that one day THEY will be the ones being cocked about by others 'not wanting separation'.
The rules are plain - under RAS achieve standard separation between participating traffic and information (and avoiding action) against non participating traffic in order to resolve the confliction. How does IFR or VFR modify these requirements?
