6. DELAYS SEEKING CLEARANCE FOR NEW AIRSPACE CLASS E
6.1 As stated above, the control frequency that will be used to
provide the air traffic service in the new Class E airspace is the
published Class G/FIA/Area frequency, 125.7 MHZ. As this is not an
approach control frequency, pilots should anticipate that
communications could be significantly delayed by frequency congestion
e.g. broadcasts by parachute aircraft.
It Is very important therefore that all pilots operating on this frequency
remember the need for brevity and standard radio telephony (R/T)
phraseology to minimise the effects of frequency congestion.
6.2 The new Class E airspace design for Williamtown is unique.
While Airservices have developed procedures and provided simulator
training to ATC staff, the affects on traffic flow in the vicinity of
Williamtown are unknown. Safety of aircraft operations is paramount
and while both flight crew and ATC staff become familiar with the new
design, delays in processing aircraft seeking access to the new
airspace Class E should be anticipated.
So we have a "Unique" airspace and AsA are forcasting delays.
This will be a very interesting experiment, I can see similarities with a "trial" a number of years ago that ended in disaster.
