flap 30 setting is 170 knots. Does that mean touchdown speed is 170 kts?
It seemed a far too fast landing to me......
170 KIAS is too fast for landing. Try 145 KIAS or close to it.
170 KIAS is maximum flap extension speed - any faster and you risk damaging the airframe.
I believe that the correct touchdown speed is vref+5.
If you have the pleasure of using Level D 767 then the FMC calculates a Vref speed (a landing speed) and depending on weight. Press INIT when inflight and you'll see different Vref's for different flap settings.
