The wings are the same as the 318/19/20 and therefore not big enough for the job - it struggles at height. And you can take full airbrake with the AP engaged, but it's only as effective as half airbrake in the 320.
Tip: Manually input VAPP as computed plus a few as you will often find the FMC computed VAPP as being too close for comfort to the FAC computed VLS. And the AT is too slow to react on gusty approaches, so consider manual thrust to save that embarrasing conundrum below 100' as your speed reaches VLS.
It's a classic case of an aircraft being developed just past it's max potential.
And you get bad botty smells on the flight deck from the fwd toilet!
