Fixed-wing FDM guy here - do those who do the work and fly them, (and who have my admiration), know what flight-data systems are installed on these types of operations?
I suspect, (and at least hope that), any such installation is going to be better than what we learned was “installed” in the helicopter involved in the DCA accident, but I am not familiar with the FARs, nor the CARs here in Canada that govern CVRs & DFDRs, etc. for rotary-wing aircraft.
I don't think this aircraft will have any recording devices fitted, but I assume it will have a GPS unit of some kind (Garmin?) which will contain a certain amount of data, in a non-volatile memory, to help analyse the flight path. It is not inconceivable that one or more of the pax may have been filming on their phones, at the time of the incident, which will obviously also be very valuable.
