ejectx3, the CTA steps outside tower hours are not on the area chart for YMAV which leads to this confusion. They are seemingly only in ERSA.
Icarus2001, yeah I totally agree "RPT route training and local knowledge" should have given them the appropriate knowledge especially as it was their home base.
It seems like there may have been some confusion as to this point on the flight deck (and from others on this forum) and I guess this is the sort of issue that CASA are looking into. As in, had Tiger made this clear to it's crews?
