And in our company we have a rule that says "best use of equipment", means use of A/T and A/P is recommended but for practice.
Unless IMC, I fly most departures by hand up to 10k. As for the approaches, I will disconnect it when the RWY is in sight or much earlier for a "raw data", which is very good value for the next simulator check and is practiced only in VMC.
Talking about capacity, it is always interesting to lose a FADEC, then having to switch the A/T off, and observe the amount of attention one has to pay to maintain if only the speed in the limits...
