Absolute crack-up FTS. When I was studying towards my ppl, good mate of mine was starting on his Commercial. He had learned to fly at this particular Bankstown flying school, drove the refueling truck and went on all sorts of ferry and private flights. I came in one day to see the CFI drawing lines through great swaithes of his log book! Fortunately he had enough total time left to meet his CPL requirements, just! Very funny to see though, as prior to that he would tend to walk around with a bit of a swagger. I'll stress that the dodgy times were logged more by ignorance than any deliberate attempt to deceive.
As far as the Qlink ICUS is concerned, well you can thank ICAO annex 1 for that. Personally I think it's a crock', and so much for world's best practice! It should be noted that under ICAO Annex 1, ICUS can only be logged up to meeting the min command hours (500) for the ATPL. After that, the logging of ICUS under ICAO Annex 1 is not legal
Sorry 'bout the slight thread drift!
