Sir Herbert
Thank you for posting the approach plates.
The use of word "then" twice in the text for the missed approach is confusing to say the least.
I believe that if a decision is made at MDA to go around, the aircraft will start to climb as soon as TOGA power is applied (A-320). After reaching 2300 ft, in managed mode, the aircraft will turn left/right to come over the VOR/NDB at 4000 ft.
Hoping, that, now someone will be able to solve this problem.
