Reply to comment by Bott in TIL that flight recorders must be able to withstand an acceleration of 3400 g for 6.5 milliseconds and that this is roughly equivalent to an impact velocity of 270 knots (310 mph; 500 km/h). by IchBinKoloss

That’s a lot of data being collected and stored for an event that’s never supposed to happen. Should aircraft like VH-OJU store data for every single cockpit conversation and every single thing that happens during the flight for 23+ years, only to be retired after a long career with zero fatalities? Such a waste of resources particularly in a time when satellites are becoming increasingly crowded.

You dont have to keep the data for all time.

I believe that the flight data and voice recorders loop after a set time, perhaps 30 minutes.

The proposed system would also only store for 30 minutes, unless there was a loss of signal. Resumption of signal, would send buffered plane data, and reset the timer.
