Thank you for the clarification.planett wrote: ↑Fri Aug 03, 2018 8:18 pm 704 requires jets of any size to demonstrate landings within 60% of available LDA before dispatch, accounting for all conditions present etc. 604 and its equivalent in the US, FAR part 91, requires landings within the LDA. The AFM will require further factoring for gravel, wet, or contamination, so it's still somewhat conservative. So the 604 regulations seem on the surface to be equivalent to 703 small aircraft regulations where landings are concerned in that no excess factoring is required for dispatch, but many small turbo props don't address the gravel case with penalties.
Taken as a whole, the jet is regulated like a large airliner for take offs, and like a turbo prop for landings with some small factoring built in, if it's operated in 604. Hardly a dangerous situation. Business jets operate around the world this way and usually are safer than their Air Taxi counterparts.
What allowed the province to operate as 604? The pilots were company personnel, but the medics experts were probably paid by the hospitals and the pax/patients were definitely not company personnel. To the untrained eye, it would seem as if it was a 704 operation all along?
