I have a question (and also appreciate the work that Dominique and colleagues do).
The list in NCO.GEN.135 includes:
(8) the journey log, or equivalent
and GM1 NCO.GEN.135(a)(8) says "’Journey log or equivalent’ means that the required information may be recorded in documentation
other than a log book, such as the operational flight plan"
but there is no requirement for an operational flight plan in NCO... (!)
SPO.GEN.140 displays the same confusion/conflict.
This is not the case in NCC.GEN.140, which contains the same GM on 'Journey Log' being ~ OFP, but actually goes on to cover OFP in NCC.OP.145 and lists 21 items it may contain.
Are NCO.GEN.135 & SPO.GEN.140 perhaps copies of NCC.GEN.140?
