Please understand that you cannot - repeat CANNOT - judge the speed of an aircraft by looking out of the window. I can't and I fly them for a living.
Agreed.
What about perceiving RoD though?
I was a pax on an A320 into Frankfurt last year and we ended pretty high on final (in fact the gear went down whilst on base), with what felt like a very uncomfortable deck angle (i.e. with the nose pitched down) and the houses getting bigger at a noticeable rate for a minute or two, before a more usual attitude was established.
I'm not suggesting that the aircraft was being flown in any way outside it's operating limits, just nearer to the edge than usual.
Although I have never particularly noticed a difference in perceived groundspeed on the same type of aircraft, I did percieve a substantial difference in the RoD on this flight - it felt approximately like an approach into LCY or a glide landing in a light single.
