Professional reviews note that while the FCOM is "dull," it is the essential source of truth for everything from overhead panel button functions to memory items for non-normal events.

Unlike previous Boeings, the 787 generates power at 235V AC (variable frequency) via two engine-driven Starter/Generators and two APU Starter/Generators. There are no constant speed drives. If a generator loses its cooling (provided by ram air via the ASE—Air Supply Equipment), the FCOM directs you to observe a "GEN COOLING" caution and land as soon as practical, not immediately.

The Boeing 787 Flight Crew Operations Manual (FCOM) is an essential resource for flight crews operating the 787 aircraft. By providing a comprehensive guide to normal and abnormal procedures, the FCOM enhances safety, improves efficiency, and supports regulatory compliance. By following best practices for using the FCOM, flight crews can ensure a safe and successful flight. There are no constant speed drives

The 787 FCOM is unique because it describes an aircraft that broke the mold of pneumatic-driven systems. Traditional Boeings (737, 747, 757, 767) used bleed air from engines to power air conditioning and anti-ice. The 787 eliminates bleed air entirely.

In the world of commercial aviation, the is the pilot’s bible. It is the definitive, type-specific document approved by the regulatory authority (FAA, EASA, etc.) that dictates every standard procedure, system description, performance calculation, and limitation for an aircraft.

Because of this, the FCOM contains new procedures for "CCS Reboot" and "Application Restart" that feel more like IT troubleshooting than traditional aviation.
