11.2 Fuel dumping

When an aircraft has informed an ATS unit that it intends to dump fuel, the ATS unit will coordinate with the flight crew the route to be flown, the level to be used and the duration of the fuel dumping. Other known traffic will be separated from the aircraft dumping fuel with specified minima. For non-controlled traffic a warning will be broadcast.

11.6 Acas manoeuvres

1. When a pilot reports a manoeuvre induced by an ACAS resolution advisory (RA), the controller shall not attempt to modify the aircraft flight path until the pilot reports returning to the terms of the current ATC clearance or instruction, but the controller shall provide traffic information as appropriate.

2. Once an aircraft departs from its clearance in compliance with an RA, the controller ceases to be responsible for providing separation between that aircraft and any other aircraft affected as a direct consequence of the manoeuvre induced by the RA. The controller resumes responsibility for providing separation for all the affected aircraft when the controller acknowledges a report from the flight crew that the aircraft has resumed the current clearance or the controller acknowledges a report from the flight crew that the aircraft is resuming the current clearance and issues an alternative clearance which is acknowledged by the flight crew.
