Thanks, that's helpful to know.
So supposing I'm flying a supported aircraft, like the default 737 for example, how often could I expect to see a system failure then?
Is it a timer based on something like "there will be a random failure every ten flights" or so, or is it based on something more like "there will be a 10% chance of failure every hour that you are in a flight"...or is it some other cunning logic?
Just asking cause I quite enjoy the occasional problem being pounced unexpectedly.
