|Action status:||Closed - Accepted|
I refer to your letter R980002 (B97/131) dated 13 January 1998 and the recommendation contained therein, that the GPS Arrival procedure from position CAMUS to Wynyard be amended so that the inbound track does not require aircraft to fly directly over the steeply rising terrain of Table Cape.
Your proposal has been examined and indeed discussed with the operator concerned, and it is agreed that your proposal is the only viable option to overcome the GPWS alert problem on this instrument approach. Accordingly, this approach will be redesigned into a sector arrival thereby allowing GPWS equipped aircraft to track to the east of Table Cape, thereby overcoming the unnecessary GPWS warnings on this approach. The revised procedure will be published in DAP-E AL 63, which becomes effective on 26 May 1998. An advanced copy of the revised procedure will be made available to the CASA Melbourne District Office as soon as it becomes available and they have agreed to issue it to the affected operators for early implementation.
