Now there you go, Mike - there are no definitive answers in Lasors for various reasons.
Lasors is a usefull aide-memoire but a waste of space in the same breath. It's full of errors - apart from which it only covers the UK interpretation.
Take, for instance, the 28 hour multi engine CPL course - it's not JAA compliant (in it's own right).
The *definitive* answers are in JAR-FCL.
