Candidates applying for Jetstar, Tiger Airways and Virgin Blue sometimes elect to undergo a practice 737NG flight experience session before going for the actual simulator test. Even though Jetstar and Tiger Airways candidates are destined to fly the A320 if successful, the initial assessment test as part of the interview process is done in a real 737-300 simulator at Ansett in Melbourne. Similarly, for Virgin Blue the assessment test is done in Virgin Blue's NG simulator at Brisbane or possibly their NG simulator at Ansett.
Either way the franchise "flight experience" Microsoft 737NG are certainly useful as far as cockpit familiarisation is concerned (and significantly less cost to the candidate) but just be aware the fidelity in some areas lacks that of real simulators. In particular, the steep turn manouvre, tested as part of the airline assessment in the real simulators, has a significantly different nose attitude than in the flight experience Microsoft trainer. None of the airlines concerned use the automatic pilot, flight directors or automatic throttle during the actual test in the real simulator.
