Furthermore, I think the term 'intermediate departure' is massively miscommunicated in the MATS, Pt 1.
As I understand it, WTS for an intermediate departure means the time difference between aircraft A departing from the runway threshold and aircraft B departing from an intermediate point, somewhere further down the runway. The threshold departure is always number one.
However, the MATS goes on to say:
Helicopters
3.62
For wake turbulence separation purposes, helicopters air taxiing across runways shall be considered to be a departure from that intermediate point of the runway.
Is this referring to the WTS required BEFORE, or AFTER the helicopter crosses? Maybe it's obvious, but I really fail to see how something so black and white as WTS cannot be communicated CLEARLY by the CAA and their publications. It really frustrates me and perhaps others...
