A good pilot has to know his machine.
Airbus machines are harder to know than Boeing or other machines.
For a no FD take OFF in the 320 you have to bear in mind, above all, these two items:
1st- select V2 in the FCU
2nd- Never engage A/THR without first selecting a speed higher than actual
Also worth noting:
There is no need for raw data navigation. You can follow the green line in the ND and even ask a DIR TO to the PM.
FLEX take off still available, and you can check it as usual in the ECAM.
FMA blank means just that: no automation assisting you (including A/THR not armed). Don't forget if you have to level off at 3000 instead of being cleared to a higher level, as usual...
If you are going to reengage automation just after acceleration, do as in the procedure. If you prefer to enjoy a little bit more and wait until well stablished in the climb, then I suggest as follows:
1-ask for "FDs ON" (basic modes engage, but still without A/THR)
2-ask for AP ON (no more asking)
3-pull altitude for an OPEN CLB
4-arm A/THR (it will engage in THR CLB)
5-manage NAV (unless HDG is required)
6-manage speed (unless other speed is required)
7-thoroughly read the FMA (to find any forgotten item)
If a single chime or any other abnormal situation arises: reengage automation immediately. You can enjoy and practice another day.
I have flown quite a few 100% AP/FD A/THR OFF sectors and its as easy and fun as in any other airplane, specially if you don't forget the first two recommendations.
