SYD delays to increase without PRM
Expect a blow-out in morning weekday holding.
PRM is being measured up for the coffin, and here are the nails:
Coffin nail 1) The manufacturer is withdrawing future support for the system.
Coffin nail 2) Airservices plans to move Sydney Approach to Melbourne, a project that specifically states that PRM cannot technically be moved and requires unspecified future technologies will replace it.
Coffin nail 3) PRM is staffed on an "emergency callout" basis by off-duty ATC staff. The newly voted certified agreement cuts payments for these shifts by around 25%. Off duty controllers will be much less likely to accept these shifts.
Airservices, we humbly await description of your mitigators...
