The structure?
I am more interested in the deviations prior to impact and why.
My understanding is it is "pilots" that put flight time in MR's - So owner pilots of a BN2 aircraft might be what you refer.
The MR requires landings to be recorded in Australia and this forms part of the Log Book - so it is only as accurate as you are Petropavlovsk - If required there are conversions to calculate "a number" on import.
6 is uncommon in most cases the Islander is not fast.
