Whopity, I know you know JAR FCL better than most of us, but still, it's nice to give a little bigger citation of it - and then it starts to make sense:
JAR FCL 1.080
.....
(b) The record shall contain the following
information:
....
(4) Pilot function:
(i) Pilot-in-command (including solo, SPIC, PICUS time)
(ii) Co-pilot
(iii) Dual
(iv) Flight instructor / Flight
examiner
(v) A remarks column will be
provided to give details of specific
functions e.g. SPIC, PICUS, instrument
flight time*, etc.
* A pilot may log as instrument flight
time only that time during which he
operates the aircraft solely by reference
to instruments, under actual or
simulated instrument flight conditions.
(5) Operational conditions:
(i) Night
(ii) IFR
As I understand it, the JAR loogbok requires:
a) remarks column in which you
may log instrument (actual/simulated) flight time, if you wish to do so
b) IFR and night columns (operational conditions) in which you log as appropriate - flight at night and flight according to IFR (which - last time I checked - stands for Instrument Flight Rules, not Instrument Meteorological Conditions)
I agree - you may log whatever you wish, the minimum is written in JAR (or any country-specific document that superseeds it), the rest is up to the owner of the logbook. Personally, I write the minimum required in the actual logbook, but the details go to electronic (Excel) logbook for easier data manipulation if/when required.
