This section provides tables and data necessary for calculating performance parameters when flight management computer (FMC) data is unavailable or needs verification, such as:

If an anti-ice system fails, or if a landing must be made on a contaminated runway with failed spoilers, these tables provide the exact stopping distance.

Boeing 787 Quick Reference Handbook (QRH) is the primary cockpit resource for managing non-normal and emergency flight conditions. By 2021, the handbook had evolved to reflect the matured systems architecture of the Dreamliner's "more electric" design.

While the Flight Crew Operations Manual (FCOM) details comprehensive normal procedures, the QRH NP section serves as a "cockpit setup" guide. It includes:

Understanding the Boeing 787 QRH: Key Updates and Operational Context (Focus on 2021)

If you need help locating specific operational data, let me know:

Boeing 787 Quick Reference Handbook (QRH) is a critical standalone document used by flight crews to manage abnormal and emergency conditions. While many core non-normal checklists (NNC) remain consistent over time, 2021 saw specific technical refinements in operational guidance and system-specific procedures.

Integration with Onboard SystemsThe 787 is a "more-electric" aircraft. Its systems are highly integrated, meaning one failure often triggers multiple EICAS messages. The digital QRH helps crews prioritize which checklist to run first—usually the one at the top of the EICAS list—and manage the "consequential" messages that follow.
