Airspace Change Proposals (ACP – CAP1616)
It’s been about 2-years since I first held meetings to discuss this matter at The Queens Hall in Burley, and Kirklands in Menston, both sessions were completely full. Since then, LBA have had several attempts to get the ACP to stage 3 – public consultation, and failed.
I am still working on the ACP and await a date on which to do further consultations in Burley and Menston, sadly neither LBA or the CAA are giving a final date. That having been said, my work continues in the background.
For the avoidance of doubt, the straight out route had been removed from LBA’s proposals, but has been reinstated following my converstaions with the CAA.
The issue flagged was ‘airspace containment,’ however, LBA then proposed several additional departure routes, all with airspace containment issues. Further detail can be found here https://lbfl.co.uk/airspace-change-proposals-cap1616-at-lba/
Should you wish to see the original ACP presentation, please get in touch.
Thanks to…
I would like to thank my aviation consultants, and 2 others for their assistance in driving the whole project forward. I’ll announce dates to discuss the ACP and responses once I have some firm information to work with. In the meantime, should you require an update, please get in touch with me via the contact page.

Airspace modernisation system (AMS).
Airspace modernisation is delivered through a series of coordinated projects across the UK. Each change goes through the CAA’s CAP1616 process (ACP) – a rigorous, transparent framework that ensures every proposal is assessed, consulted on and justified before it is approved.
The AMS considers airspace at 3 distinct levels:
- Changes below 7,000 feet (FL70). Airports are responsible for their own arrivals/departures in parallel with the network changes above.
- Systemised Airspace 7,001 to 24,500 feet. NATS are responsible for deploying systemisation in the lower level network above 7,000 feet.
- Free route airspace NATS is responsible for deploying Free Route Airspace (FRA) in the high level network, allowing aircraft to fly a fully optimised flight path based on factors like weather and windspeed, which improves efficiency and reduces flight time, fuel burn and emissions.
When will airspace modernisation happen?
The strategy is being delivered in phases, with some key milestones already delivered. Changes already live include upgrades to airspace in the southwest, Scotland, and to Luton arrivals. Other change projects are in progress across the UK.
