Further to this, also the only time you may log P1/under supervision or PICUS on a single pilot aircraft class is after a sucessful flight test with an examiner. The exception is of course on integrated courses, but this is irrelevant to a PPL forum.
Alphamale,
The FAA reg you state is also why you will see some very cheap deals on multi engine hour building in the US, be wary as often only half this time is "loggable" under JAR.
