What is AFM on Boeing 737? (Airplane Flight Manual)

The Airplane Flight Manual (AFM) is a crucial document for all pilots operating the Boeing 737 aircraft. It provides detailed information about the specific model and variant of the aircraft, including its systems, limitations, performance data, and procedures. The AFM is developed by the aircraft manufacturer, Boeing, and approved by aviation regulatory authorities, such as the Federal Aviation Administration (FAA) in the United States.

The primary purpose of the Airplane Flight Manual is to ensure safe and efficient operations of the aircraft. It serves as a comprehensive guide for pilots, enabling them to operate the Boeing 737 safely in all phases of flight, including takeoff, climb, cruise, descent, and landing. The AFM contains vital information on aircraft performance, weight and balance, fuel management, operational procedures, emergency procedures, and more.

The AFM is divided into several sections, each addressing different aspects of the aircraft’s operation. It typically includes sections such as:

  • General Description: Provides an overview of the aircraft’s systems, including airframe, engines, avionics, and electrical systems.
  • Limits: Outlines the aircraft’s operational limitations, such as maximum altitude, speed limits, weight limits, and center of gravity limits.
  • Performance: Contains performance charts and tables that help pilots calculate the aircraft’s takeoff, landing, climb, and cruise performance based on various factors like temperature and altitude.
  • Procedures: Describes the step-by-step procedures for different flight phases, including pre-flight checks, engine starting, before takeoff, climb, cruise, descent, and landing.
  • Emergency Procedures: Details the actions to be taken by pilots in emergency situations, such as engine failure, fire, loss of pressurization, and more. It also includes information on abnormal situations, system malfunctions, and troubleshooting.
  • Supplements: May include additional information related to specific aircraft configurations, optional systems, or modifications.

Importance of the Airplane Flight Manual

The Airplane Flight Manual is a vital resource for pilots as it ensures that they have access to accurate and up-to-date information about the aircraft they are operating. It helps pilots make informed decisions and execute procedures correctly, contributing to safe and efficient flight operations.

By providing comprehensive details about the aircraft’s systems, performance, and operational procedures, the AFM enables pilots to understand the capabilities and limitations of the Boeing 737. It helps them plan their flights, calculate fuel requirements, determine takeoff and landing performance, and handle various abnormal situations.

The AFM also plays a crucial role in the certification and regulatory compliance of the aircraft. It contains information that has been reviewed and approved by aviation authorities, ensuring that the aircraft meets the required safety standards. Compliance with the AFM is mandatory for pilots and operators to maintain the airworthiness of the aircraft.

Additionally, the AFM serves as a reference for training pilots. It is used by flight instructors and training organizations to teach pilots about the specific procedures and systems of the Boeing 737 aircraft. This ensures standardized training and enhances pilots’ knowledge and proficiency in operating the aircraft.

Changes and Updates to the Airplane Flight Manual

The Airplane Flight Manual is a living document that undergoes revisions and updates over time. These changes are necessary to incorporate advancements in technology, address safety issues, and reflect modifications or improvements made to the aircraft.

Boeing regularly issues revisions to the AFM in the form of Service Bulletins, which contain updates, corrections, or additional information. These bulletins are communicated to operators and pilots, who must ensure that their copies of the AFM are current and reflect the latest revisions.

Pilots are responsible for staying informed about any updates to the AFM and complying with the latest procedures. This includes being aware of temporary revisions (TRs) issued by the manufacturer, which address specific issues or temporary changes to operating procedures.

Aviation regulatory authorities, such as the FAA, may also issue Airworthiness Directives (ADs) that require specific modifications or inspections as a result of safety concerns or changes to the AFM. Pilots and operators must adhere to these directives to ensure continued airworthiness and compliance with regulations.


The Airplane Flight Manual is an essential document for pilots operating the Boeing 737 aircraft. It provides comprehensive information about the aircraft’s systems, limitations, procedures, and performance, enabling pilots to operate the aircraft safely and efficiently.

By adhering to the guidance and procedures outlined in the AFM, pilots can make informed decisions, handle emergency situations, and ensure regulatory compliance. Staying updated with any changes or revisions to the AFM is crucial for maintaining airworthiness and operating the Boeing 737 aircraft safely.
