[3]Access to Airspace[/3]

1 Understand VFR Capacity of Terminal Airspace

There is no available measure of the capacity of terminal airspace to support VFR traffic whilst it is used by different volumes of IFR traffic. As a result airspace change sponsors are able to make unsupported statements about airspace access for VFR traffic which are not subsequently delivered. Moreover there is no benchmark to assess if the VFR access provided in terminal airspace is reasonable.

To provide a benchmark, terminal airspace needs to be modelled under a range of IFR traffic conditions. This modelling methodology would be agreed by all users and become the means by which terminal airspace resource is allocated openly and transparently. This would then be used to assess the effectiveness of airspace structures for VFR operations and could reflect the efficiency and environmental benefits that would accrue.
