Pilot Proficiency Check (PPC) on Multi
 

Hey, whats this latest buzz about PPC ?
It is being heard, during latest inspections by FIDs , it has been brought to the notice that PPC with a DGCA Approved Examiner(for that particular aircraft) is a mandate every 6 months for A/c below < 5700 .
But, what sense does it makes, if you are already flying mainting recency and having current IR, then why PPC every 6 months ? :/
Does, anybody aware if there is any circular on this by DGCA?
Also, if somebody can tell if PPC can be done along with the IR Check.??
