Re: Do PICUS hours count?
As Sky Wave suggests, the hours gained in successful completion of licence and rating skill tests may be counted towards the 100 hours PIC requirement. However, according to JAR, these flights should not have been recorded as PICUS, which applies only to a co-pilot "on an aeroplane on which more than one pilot is required under the type certification of the aeroplane or as required by JAR–OPS". This is yet another example of LASORS getting it wrong.
The skill tests that would count towards PIC time during modular training would be only the PPL Skill Test, CPL Skill Test, MEP Class Rating and IR Skill Test - progress checks and club 'checkouts' do not count. Only a full pass may be counted towards PIC time, partial passes should be recorded as Dual flight time.
PICUS should not be recorded on an integrated course (see above) and SPIC is a quite different proposition - 50 hours is specifically written into the integrated course syllabus and is, therefore, not relevant to modular training
