Flight Time Vs. Air Time Personal Logbook in General Helicopter Operations Posted January 1, 2018 · Report reply I am not sure of the regs in Canada and not getting into that, but only in aviation, when you hire an excavator or a crane you pay on engine hours not just when the tracks or the boom operating , why with aircraft only on airtime, because companies look at it as a big expense. They will pay huge money for consultants that achieve nothing and **** things up. Engine still running and components are still getting a wear factor. With the way satellite tracking is gong the fire departments and companies will auto invoice of sat tracking. The Sat tracking will record the movement attached to their invoice system, another way for them to save dollars at the expense of operators. Only drives the industry into a bear minimum survival mode. If you are not getting 1000 hours per year per aircraft in years to come the industry will hit rock bottom. Oh I forgot that for every operator that falls over or gets out, another on comes along and thinks that all before were doing it wrong.
