K, thanks for the frog. The sugar will help with the rising anxiety…
Not sure if more concerned with the quite interesting, sincerely held but divergent opinions of the thread on the other PRU or what’s happening at Darwin every night from 1230 / 2030 UTC from 03271230 to 05212030.
I know Australia is a democracy but some of the posters on the thread are obviously flying jets for QANTAS / VIRGIN / JETSTAR but hmmm!
Sunny SA looked at the Darwin Noise Abatement Procedures and posted on thread of interest named “Separation issue involving Boeing 737, VH-VXH, and Airbus A320, VH-VGV, near Darwin”.
Effectively following the NAP means we have RRO (Reciprocal Runway Operations) [not as sexy as SODPROPS] happening most nights in Darwin within a TRA using some CTAF like procedures under the watchful eye of Darwin FLIGHTWACH! (Rumoured to be RAAF Tower controllers not holding an APPROACH rating. Sitting in the TWR with a radar display.)
I suppose it should make everyone feel better but it just confirms to me Australia’s one true Centre of Excellence is mediocrity. It’s obvious by listening to LiveATC (the Thursday following the occurrence between 1500/1630 is interesting) that the approval to enter the TRA is a joke and just yet another bullshit box ticking exercise.
Sunny SA also commented on the implied misuse of TCAS after noting the overt requirement in the TRA NOTAM with “Given TCAS was designed to operate as a last-resort safety net, when did TCAS switch to being a primary defence“.
I replied on same thread…
Sunny SA…Re TCAS…
so the following questions arise to clarify your query further…
a/. Would an aircraft not equipped with TCAS get approval to operate in the TRA?
b/. Would an RPT jet with unserviceable TCAS get approval to operate in the TRA?
And finally the control questions…
c/. Can an RPT jet with unserviceable TCAS fly from YMML to YSSY wholly contained in A/C airspace with no TRA/TIBA?
d/. Can an RPT jet with unserviceable TCAS fly from YSSY to YMIA where last segment is Class E/G airspace and CTAF?
Some interesting things arose in AsA after Uberlingen,
TCAS was not supposed to be used in target level of safety determination, only resultant level of safety determination ie a true airborne safety net akin to the STCA in the ground based system. One could be forgiven if it appears the distinction is somewhat blurred?
Mind you, senior executive management and the board of ASA after Uberlingen were supposedly assured that a controller in OZ would never resolve compromised separation by a level change. Yeah right, good luck with that!
When we start using safety nets to mitigate staffing issues / traffic levels or just basic air traffic control then the threads don’t save anyone from the high wire act, no matter how easy it looks when done by professionals… and we might as well be in Africa!
Isn’t there a company called Landbridge that already does leasing work in Darwin, maybe they would help out with a contract doing the ATC night shift in Darwin?
I am pretty sure China uses similar ATC equipment.
Maybe just the script of another Utopia episode…
Sigh!
