Q: During a checkout in a Piper Cherokee, (I had only Cessna experience), I asked the CFI why Piper has me check the mags at 2,000 rpm and Cessna at 1,700 rpm on what is, essentially, the same engine?
My opinion is that it is not a deal breaker to not have exactly the rpm in question, just close, and that it is the percentage of change during the mag check that is what is really important. Can you help us understand this?

A: This is a question that may have crossed many a pilot’s mind as they transition from one aircraft type to another. First of all, the most important place to check for the proper procedure for the specific aircraft you are going to fly is to review the airframe manufacturers Pilot’s Operating Handbook (POH).
