Reduced Occupancy Times
BOAC & Forget
As one who was also involved in the LGW RETILS and the FR turn off. I can confirm that occupancy times reduced subsequent to the introduction of both initiatives, enabling consequential capacity increases to be introduced.
Reduced occupancy times allow reduced final approach spacing, subject of course to Vortex Wake minimum requirements.
Use of MLS in LVP's should enable reduced final approach separation as the MLS signals are not distorted by aircraft/objects on the runway.
