results of these trials indicate that al¬though VLJs are slower than commercial airlines, the effects on airspace sequenc¬ing are manageable without significant increase to the controller's workload.
According to an article posted by Paolo Sommariva, of the technical standards committee of the Air Taxi Association,
on the association's website in 0ctober 2008: "The critical factor is the touchdown speed, which requires VLJs to slow down much more than other jets. This results
in an extra separation on final approach for, say, a Boeing 737 following an Eclipse. We observed typically an extra 3-4 miles required additional separation. 0n the other hand, a VLJ following an airliner will have increased separation for wake turbu¬lence concerns. This led to some com¬ments suggesting different techniques of installing separate glide paths for VLJs...0n take-off the separation with faster airliners following VLJs could easily be resolved with rate-of-climb restrictions."
According to the US Federal Aviation Administration, early experience with VLJs suggests the average age of VLJ pilots is 47 and that 78 per cent of them have previous experience of flying with glass cockpits. The current generation of VLJs (Cessna Mustang and Eclipse 500) cruise mainly at flight levels be¬tween 10-40,000ft and most between 10-28,000ft.
But, there are still many unknown is¬sues, especially with the numbers and lo¬cation of the new jets. The current order figures suggest that Europe will account for between 20 to 25 per cent of all VLJ deliveries in the short-term (2009-2010), with this percentage remaining fairly static or slowly eroding as the North American and Middle East markets pick up the pace of economic recovery. They may take longer to arrive in Europe than many forecasters have predicted but, credit crunch or no credit crunch, the VLJs are on their way.
