Looking back at my quotation from the AMC, it is clear that they expect you to record what your function was
I think we look at the indexing format to see what they are saying here, in my opinion parts 4 and 5 are not related specifically to part 3 or they would be 'vi' and 'vii'.
AMC1 FCL.050 Recording of flight time
GENERAL
(a) The record of the flights flown should contain at least the following information:
(1) personal details: name(s) and address of the pilot;
(2) for each flight:
(i) name(s) of PIC;
(ii) date of flight;
(iii) place and time of departure and arrival;
(iv) type, including make, model and variant, and registration of the aircraft;
(v) indication if the aircraft is SE or ME, if applicable;
(vi) total time of flight;
(vii) accumulated total time of flight.
(3) for each FSTD session, if applicable:
(i) type and qualification number of the training device;
(ii) FSTD instruction;
(iii) date;
(iv) total time of session;
(v) accumulated total time.
(4) details on pilot function, namely PIC, including solo, SPIC and PICUS time, co-pilot, dual, FI or FE;
(5) Operational conditions, namely if the operation takes place at night, or is conducted under instrument flight rules.
I read it as Part 3 i-v applying to FSTD's? I do however think it's unclear because if parts 4 and 5 related only to flights in helicopters then they should fall under part 2. It was due to that fact that this was unclear that I referred to the logbook example pages - which I assumed to be correct.
