So, stated above is: -
"Sec. 61.51
Pilot logbooks.
(e) Logging pilot-in-command flight time.
(1) A sport, recreational, private, or commercial pilot may log pilot-in-command time only for that flight time during which that person—
(i) Is the sole manipulator of the controls of an aircraft for which the pilot is rated or has privileges;"
With the fear of opening a HUGE can of worms... how does this relate to the 90 day rule and a "Safety Pilot"
There has been a huge amount of debate as to whether or not a PPL in the RHS is a passenger or not, and although I can not find the quotes, I am fairly sure the CAA conclusion is that a RHS PPL is a passenger in a single crew aircraft.
So this paragraph seems to allow a 90 day current PPL to take an aircraft into the air and hand control to a non 90 day current PPL to fly ciruicts as it only has the privelidge not currency statement.
I think this would be a good way forward for safety.
