Many years ago a New Zealand CPL turned up at a South Pacific island claiming lots of hours check and training in BN Islanders as well as extensive hours on Chieftains. The chief pilot soon discovered this pilot could not even start an Islander without resorting to a written checklist to tell him what to do next. Investigation of his log book certainly revealed extensive Chieftain time all written in immaculate style with the same pen for weeks at a time with most days flying being between 4-7 hours a day. But comparing the distances between the various destinations, it soon became obvious that the ground speed must have averaged 300 knots for each leg.. in a Chieftain.
