Kraut, I've yet to see an EZY 319 keep 160 to 4 at Gatwick.
Thats's because the teaching is to maintain the "selected" speed i.e. 160kts to 5dme then go "managed" and select the gear down. It generally takes a mile for the speed to drop to 150 kts so we have maintained 160+/-10kts to 4dme.
The aim is to be stable and in landing config by 1000ft above TDZ. What works in still air is 180kts to 6dme, 170kts to 5dme and 160kts to 4dme. Observing those rules of thumb should have the aircraft stable and on approach speed at 1100ft.
