I don't remember it going tech anymore than any other turbo prop. The Darts where near on bullet proof although you could fry them on start if you didn't pay attention.
We used to try and get from TOD to the threshold without touching the power levers, you could make limited power adjustments with the fuel trim switches.
It would do 290kts IAS in the descent and you could drop the air brakes (main gear) at up to 310kts. I have trawled these figures from memory so may be incorrect. The avionics where state of the art clockwork stuff which would put majority of airliners at the time in the shade.
