MD-11 Flight Crew Operating Manual (FCOM) – Detailed Content Summary

What is the MD11 FCOM?

The Flight Crew Operations Manual (FCOM) is the official manufacturer-approved document provided by McDonnell Douglas (and later Boeing) to airline operators. It is not a light read or a quick reference card; it is the comprehensive technical bible for line operations.

The MD-11 FCOM is typically broken down into major volumes:

• Volume 1: Systems Description – Detailed explanations of hydraulics, pneumatics, electrical, fuel, flight controls, and the unique MD-11 autoflight system.
• Volume 2: Operating Procedures – Normal procedures, expanded checklists, supplementary procedures, and non-normal (emergency) checklists.
• Volume 3: Performance and Dispatch – Takeoff, climb, cruise, and landing performance data; Weight & Balance; and MEL (Minimum Equipment List) guidelines.

B. Fuel System

The MD-11 fuel system is complex due to the need for Center of Gravity (CG) management. The aircraft does not use conventional trim tanks in the tail but manages fuel distribution to optimize CG for drag reduction (Supercritical Wing efficiency). md11 fcom pdf

• Tanks: Left Wing

MD-11 Flight Crew Operating Manual (FCOM) is the primary technical document used by pilots to operate the McDonnell Douglas MD-11 trijet. It provides comprehensive descriptive information and procedures for normal, abnormal, and emergency flight phases. Slideshare Core FCOM Structure

The manual is typically divided into multiple volumes or chapters to manage its extensive technical data: Volume I: Systems Description MD-11 FCOM — Article MD-11 Flight Crew Operating

: Detailed analysis of the aircraft's advanced "glass cockpit" avionics, including the Electronic Instrument System (EIS)

, Flight Management System (FMS), and automated Aircraft System Controllers (ASC). Volume II: Operating Procedures : Step-by-step instructions for every flight phase. Normal Procedures Volume 1: Systems Description – Detailed explanations of

: Checklists for cockpit preparation, engine start, taxi, takeoff, and landing. Abnormal and Emergency Procedures

: Response protocols for system failures (e.g., hydraulic issues or engine fires). Volume III: Performance Data

: Detailed tables for takeoff and landing distances, fuel burn, and weight limitations based on specific engine types like the GE CF6-80C2 or PW4460. Slideshare Key Technical Systems Covered MD11 Flight Crew Operating Manual vol.2C rev.60 KLM.pdf

1. SmartCockpit (Industry Standard)

This is the #1 resource for real-world cockpit documentation. They offer a searchable MD-11 FCOM PDF (often from a generic or European operator). Please note: SmartCockpit requires a paid subscription, but the quality is unmatched—scanned directly from McDonnell Douglas originals.

4. Key Technical Features Unique to MD-11 in FCOM

• Three hydraulic systems (Left, Center, Right) with no mechanical reversion — flight control laws require at least two.
• Automatic stabilizer trim and tail fuel tank for CG control (must be understood for takeoff/landing).
• Advanced AFCS (Automatic Flight Control System) with autoland capability to CAT IIIb.
• EICAS (Engine Indication and Crew Alerting System) with synoptic pages.
• Nosewheel steering limited to 50° left/right for taxi; tiller for high-angle turns.
• Thrust asymmetry procedure after engine failure (MD-11 has powerful rudder authority but specific rudder limiting).
• Slats and flaps sequencing (different from DC-10).
• Windshield heating and rain removal system unique to MD-11.

B. MCDU Pages

• IDENT: Aircraft model, engine type, navigation database validity.
• POS INIT: Present position entry, alignment of IRUs (Inertial Reference Units).
• PERF INIT: Gross weight, fuel on board, zero fuel weight, cost index, cruise altitude, and step-climb data.
• ROUTE: Departure/Arrival airport selection, airway routing, and waypoint entry.
• TAKEOFF: Flap settings, V-speeds (V1, VR, V2), and CG trim setting.
