1)
Operator policy is max use of auto flight. However, allowing any level of automation for practice "during initial departure and approach" when consideration is given to workload and environmental conditions.

2)
I agree completely with my company manual, although my definition of when initial departure ends and when approach begins maybe a bit more stretched than intended. Also the manual doesn't say how often practice is necessary.

3)
Departure:
Normally I will fly with FD/AT on, AP off till clean, and if turning departure till first turn completed - ranging from 4000 - FL100 feet typically. If I am tired or in a busy place (and/or the other guy is tired or not up to par) I will turn the AP on in 1000 feet.

I happily fly raw data departures (A/T off as well) WHEN situation permitting. For me this means home base or non-busy environments + good wx till acceleration altitude, incase of engine failure. I often also choose depending if I find the departure interesting to hand fly (no point or fun in hand flying a straight RNAV departure). I continue to TOC or till I have had enough. I do this 3 or 4 times on average pr. month.

About raw data level off:
Yes, everyone need practice! That is if you want to do them nicely.
Nicely for me means: On speed, at 1500 before, start reduce to exactly 1000fpm, so that you hit 1000fpm at 1000 feet before exactly. Keep exactly 1000fpm till level off. Level off at exact altitude on exact speed.
Most that claim they can do this, but never practice will be all over the place with speed and v/s, and climb with 200fpm the last 500 feet because they are afraid they will overshoot.

This is a good coordination exercise and will help you "keep in touch" with the aircraft in my opinion.


Approach:
The same criteria as above. I happily fly raw data from TOD but most often passing FL200 - FL150. This happens 2 times pr. week on average. Raw data also means selecting VOR/ILS full rose, so there is no descend path to look after.

Rest of the approaches are with full auto till G/S capture normally. And some to 800-500 feet if I am tired or lazy.

All assuming fair weather of course, with cloudbase lower than 800-1000 feet (or higher if high terrain) I don't fly raw data.

Visual approaches and the occasional circling is done with as much help as possible, like programming nice tracks in the FMC and so on and flying with the autopilot until a stressless takeover can be made. Why make unnecessary stress, when you can really enjoy the odd visual approach with nice orientation from e.g. the path indicator (combined with the eyes of course). If you can't do without the toys, it's another matter thought.


Why raw data:
First, I don't want to become a button pusher that can't remember how to fly! Second, I enjoy it.
