In approach phase aircraft fails to decel in an acceptable amount of time. The AC persists to not decelerate and has to be encouraged to decelerate to acceptable speeds, at Flaps 1 the AC does not slow below the Flaps 2 speed (requires excessive speed brake) , same with Flaps 2-3 , requires constant speed breaking right up to flaps 3 in order to get it to decelerate . It’s like it has to be reminded it’s time to decel otherwise it will just hold a constant speed until the last 1000ft. the AC does slow in its own but waaay to late and prompts a go around without an awful lot of intervention. activating approach phase often does nothing for speed and AC does not even attempt to decel sometimes. (yes the flight plan and Perf pages are all correctly filled out.) I believe this to be attributed to the VNav behaviour issues others have mentioned , I’m not sure the AC sometime knows where it is on the FPln also the random CTD’s that still linger spoil long haul attempts and short haul. Bonus is I haven’t had a WASM issue in weeks.. but with CTD’s that doesn’t matter.
