Airspace associated with the RAAF's Edinburgh Base consists of Restricted and Danger Areas, and is depicted on various aeronautical charts, i.e. VNC-8.
This classified airspace has defined vertical and lateral boundries, which have applied continuously (i.e. H24) except for areas released to Adelaide Soaring Club and Ballooning by Notam.
A minor change was made to the times of classification of this airspace, effective from Thursday 29th November 2007, as described below.
2. AREA AFFECTED
The changes effect all areas of the Edinburgh Restricted airspace, including R253, R265 A, B, C, & D and D258 A & B (see VNC-8).
The change involves the de-classification of the Restricted and Danger Area when not required by the Military Authorities. This results in large areas of the airspace changing to either Class G, Class C or Class A airspace only when de-activated by NOTAM.
3. CHANGE DETAIL
The details of the changes are best depicted using a current copy of VNC-8, and only apply when de-activated by NOTAM.
1. The existing 2500 Ft LL Class C (to 20 DME) airspace around Adelaide is extended through R265A.
2. The existing 4500 Ft LL Class C (to 36 DME Adelaide) is extended through R265A.
3. The existing 8500 Ft LL Class C (to 50 DME Adelaide) is extended through R265B.
4. The existing FL125 Class C (to 65 DME Adelaide) in R265C applies. The 8500 Ft LL Class E airspace which underlies this airspace continues to apply (good lookout).
5. The existing FL180 Class A (to 90 DME Adelaide) in R265D applies. The 8500 Ft Class E airspace which underlies this airspace continues to apply (good lookout).
The de-activated airspace is subject to a 30 minute recall. The status of the airspace may be determined in flight by reference to Adelaide Approach on 128.6.
The Notam is unlikely to require a listening watch on Adelaide Approach 128.6 (as often applied in the past). If an airspace recall is made, the Controlling Authority (AirServices Australia) will broadcast on 128.6 and will directly contact the relevant Gliding Clubs.
5. OPERATIONAL CHANGES
It is recommended that Clubs / pilots continue to operate within the published confines of the vertical and lateral limits of the Edinburgh Restricted Airspace unless it has been positively determined that the relevant airspace has been de-activated. This may be achieved by,
a) A review of NOTAM,s before commencing a flight, or
b) A check with Adelaide Approach on 128.6.
Operations in this fashion will help avoid violations of Controlled Airspace.
These changes will result in a height increase for Controlled Airspace traffic into / out of Adelaide. Pilots must ensure (as always) compliance with the Lower Limits of the Controlled Airspace (both when the airspace is active and when it is de-activated), as it is likely thee aircraft will be near the Lower Limit steps.
6. CHART CHANGES
It is expected that the changes described above will not be incorporated in Chart changes until the 5 June 2008 chart change cycle.
The recommendation in (5) above is reiterated.
