While general operational guidelines are standard across fleets, certain systems, configurations, and procedures remain deeply specialized. This comprehensive analysis dives into the exclusive technical architectures, advanced flight deck interfaces, and unique handling characteristics detailed within the . 1. The More-Electric Architecture (MEA)
This instantaneous reaction softens the impact of the turbulence, smoothing out the ride and reducing the stress loads on the composite wings.

One of the most notable features exclusive to the 787 is its transition from engine bleed-air to an entirely electrical architecture, fundamentally changing normal and non-normal checklists in the FCOM:
The FCOM mandates standard profiles for the five massive 15.1-inch LCD screens dominating the instrument panel.

Most recurrent training doesn’t cover EPR because it’s astronomically rare. But if you see a “CAB FAN 1/2/3/4 FAIL” cascade, expect the FMC to automatically limit your ceiling.
The 787 FCOM Exclusive also offers a range of benefits for airlines, including:
: The importance of verifying switch positions during flight to prevent unintended thrust loss.
To smooth out passenger ride quality, the 787 utilizes symmetric deflection of the flaperons and elevators. The system senses sudden vertical accelerations via inertial sensors and immediately commands micro-adjustments of the control surfaces to counteract the bumps before they impact the cabin. But if you see a “CAB FAN 1/2/3/4
Rather than memorizing endless step-by-step physical switch throws, the FCOM guides crews through managing automated system reconfigurations.
Comparing 787 systems to other aircraft like the .
Traditional commercial airliners rely heavily on pneumatic bleed air tapped from the engine compressors to power environmental control systems (ECS), wing anti-ice, and engine starts. The Boeing 787 completely disrupts this paradigm by eliminating the traditional bleed air system, replacing it with a .
While the Boeing 777 introduced Fly-By-Wire (FBW), the 787 FCOM introduces advanced control laws exclusive to the Dreamliner. If you are a student pilot
If you are a student pilot, an aviation professional, or just an aviation geek looking to take your understanding to the next level, I can help you with a few next steps.
The 787's Automatic Flight System is engaged via the Mode Control Panel (MCP) on the glareshield. The FCOM details the specific logic for engaging the autopilot:
The 787 electrical system is unprecedented in scale. The FCOM outlines a distribution network powered by six Variable Frequency Starter Generators (VFSGs):
