I use this flight to do the usual stalling, steep turns, PFL, EFATO, a bit of slow flight, spiral dives, unusal attitudes, possibly an electrical fire in the air drill and back for a couple of circuits.
I then point out any weakness and sign the appropriate areas with '1 hours flight as per JAR-FCL'.
I sign it as them completing the JAR-FCL requirement, not as a level of competence (although a quite word would be said).
