Independent Parallel Approaches

Heathrow previously consulted on a proposed short-term change to the way some aircraft arrive at Heathrow.

This project was known as Independent Parallel Approaches (IPA) and involved some new arrival routes into Heathrow from the holding stacks. Some of these flight paths could have overflown areas that are not affected by Heathrow arrivals today.

We have discontinued this Airspace Change Proposal (ACP), due to the successful progression of our broader ACP for airspace modernisation.
