A Pilot Operating Handbook (POH) is a crucial document for pilots, providing essential information about a specific aircraft. It includes details on operating procedures, performance data, and limitations, ensuring safe and efficient flight operations. The POH serves as a reference for pre-flight checks, emergency procedures, and normal operating guidelines. The handbook is tailored to each aircraft model, such as the Cessna 172 or Piper PA-28, and is required by aviation regulations. Pilots must familiarize themselves with the POH to understand the aircraft's systems and capabilities, which enhances safety and compliance during flight.
