According to JAR-FCL 1.080 b) vi one may log a series of flights in the same entry as below:
(vi) If the holder of a licence
carries out a number of flights upon the
same day returning on each occasion to
the same place of departure and the
interval between successive flights does
not exceed thirty minutes, such series of
flights may be recorded as a single
entry.
Now, say I have a six sector day according to the above, and want to use this rule to log my flights. There will be 12 different on/off-block times and 4 different airports (three destinations, one origin). What do I put in the logbook? Off-block for the first flight and on-block for the last? From where to where? Origin to origin? Do I have to make notes anywhere about the times of all flights and notes about which airports I've flown to? I assume I have to log actual block times and not log the time from the first off-block to the last on-block?
What if schedule says 25 minutes between each flight but actual conditions are 31-32?
Does it differ at all between authorities within JAR?
Anyone has any experience on how to interpret this?
