Absolutely correct Bloggsy,
Used to be able to get a waiver to that rather interesting requirement but not any more. Can anyone tell us why that restriction is in there at all, it seems a bit strange. Have tried to work it out, but my logic is obviously different to the boys in Canberra.

The 52nm requirement is there to provide some opportunity for acft departing on the CLIFFY and KAJUN SIDs to climb above the inbound traffic. There are no reciprocal requirements on these SIDs so we usually give departing acft a requirement to reach FL160 by 36PH or 5miles to run PEPPA, or some such. Most aircraft seem to be able to do this, except in summer. The FK50's, in particular can struggle, but so too can the others. If we got rid of the 52nm reqmt, departing traffic would have to maintain FL130 until nearly CUN before we could give them climb. This would then cause all kinds of problems with inbound traffic, especially those not yet on radar.
Our discretion to remove the 52 rqmt was taken away from us about 12 months ago. My recollection is that an inbound acft asked for it to be cancelled but this was denied due departing traffic. Non-the-less, the acft failed to meet the requirement resulting in someone copping a hard vector. The powers that be decided that we could no longer cancel the reqmt unless it was need for separation.
It can get quite congested around PEPPA. It is not unusual to have 2 or 3 turbos on the KAJUN SID, 2 Ba146's on the CLIFFY SID and two jets inbound on the PEPPA STAR. The CLIFFY SID turns and meets the other at KAJUN and all acft are assigned FL130! Thats why the SIDs are sometimes cancelled and you get vectored to the east and southeast.
