I spent 3 years in with RFDS(QLD) and approx 20% of my logged hours were I.F.(mostly with autopilot but determined as IF by CASA Definition). Last couple of years flying RPT Jet and less than 2% logged I.F. (same definition). Flying RFDS you can never have too much IF experience! I now have about 8000TT and 890ish I.F. and have always used the same criteria for determining IF.
