The CAA has this week (30th October) ruled that Heathrow’s airspace change proposals cannot progress to the next stage (of the CAP1616 process) because they took a different approach to the one they’d engaged on and stakeholders were not given an opportunity to provide feedback!
Heathrow will be able to resubmit their proposals for approval to the next stage once they can satisfy the criteria. However, this is likely to add a further delay to the progress being made with a public consultation on flight path options not expected until 2025.
