A quick check of the IOSA web page shows the neither Qlink or Cobham comply with IOSA or report to IOSA. That means that the jet operation is and will be operated to a standard where the recognised bench mark for auditing and operational safety standards is not audited by an IOSA representative.
I wonder if both might be captured under the Qantas banner. I'd be surprised if QF just handed over the stencil for the roo on the tail, said "here ya go, paint yer tails and yer off", without any oversight.
