Q: What is the difference between a POH and a PIM?
A: POH - Pilot's Operating Handbook is an FAA approved document and is serial number specific to match your individual aircraft. The FAA requires that you keep one of these manuals on your plane at all times to meet requirements. The PIM - Pilot's Information Manual is for information and for training purposes only.
