"Bushy" quite correct. It's interesting to read that there may appear to be two sets of rules for both GA & the Airlines. Whether it be so or not the underlying factor is that whether yr in a GA plane taking off for Eg. from an airport without rwy lighting for whatever reason or in a High Capacity Plane doing the same thing the 'cargo' is exactly the same, mine, yrs & everyone elses life isn't worth any less if their not in a so called higher protected environment as the airlines.
The only differnence to the level of safety of the two diff sectors here (GA & Airlines) is the level of maintenance. Flight decisions should be the same whether it be from a Jumbo jet skipper or a C172 PVT pilot.
