Why might a pilot refer to the Pilot Operating Handbook during a flight?

A pilot refers to the Pilot Operating Handbook (POH) during a flight primarily to understand the aircraft's capabilities. The POH contains essential information about the aircraft's performance characteristics, limitations, and operating procedures. This information includes data on takeoff and landing distances, weight and balance considerations, fuel consumption, and emergency procedures. Knowing these capabilities allows the pilot to make informed decisions regarding flight operations, ensuring safety, efficiency, and compliance with aircraft performance standards. The POH is a key resource for pilots to maintain situational awareness and to ensure that they are operating within the limitations of their specific aircraft model.
