Pilot: "EICAS says 'HYD SYS L PRESS LOW.' The FCOM algorithm suggests I check the Left Engine Driven Pump (EDP) switch. Because the HYD system is self-isolating, the FCOM tells me to do nothing unless I see Secondary failures."
Unlike the 777, the 787’s fly-by-wire system offers automatically. The FCOM explains that during turbulence, the ailerons and elevators will twitch out of sync with pilot inputs to cancel out atmospheric disturbances. Pilots not familiar with this often think the control column is broken; the FCOM assures it is working.
The 787 FCOM clarifies that the Dreamliner uses no Integrated Drive Generators (IDGs). Instead, it uses VFSGs that produce 235–460 Hz AC power. The FCOM explicitly warns: "Do not connect external ground power if the VFSG is outputting frequency outside 380–480 Hz." 787 fcom
This article provides an in-depth analysis of the Boeing 787 FCOM, exploring its structure, its evolution from paper to digital, its critical role in flight safety, and why it remains the "final word" for flight crews worldwide.
On Boeing jets, the autothrottle typically moves the thrust levers. On the 787, they are (no cables). Pilot: "EICAS says 'HYD SYS L PRESS LOW
Contains limitations, normal procedures, and performance data for various flight phases. Volume 2 (Systems):
The manual provides the precise data needed to maximize the 787's 25% fuel-efficiency advantage over previous generations. Pilots not familiar with this often think the
The FCOM is typically divided into two main volumes and a set of supplemental manuals: Volume 1 (General & Performance):
