Clear illustrations of system A, system B, and standby hydraulic systems.
It is important to ensure you are using the correct version of the guide. While the 737-800 (NG) and 737 MAX share commonalities, there are critical differences in:
The 737 requires pilots to memorize immediate action items for critical emergencies (like an Engine Tailpipe Fire or Runaway Stabilizer). Use the schematics in the guide to visualize exactly what valves are closing or what power is being cut when you execute these memory items. A Note on Copyright and Official Sourcing
Intricate schematics trace electrical, hydraulic, and fuel lines clearly.
While many historically used a physical book or a , the material has evolved into a powerful digital tool. b737 cockpit companion pdf
To maximize the benefits of the B737 Cockpit Companion PDF, pilots should:
The primary advantage of the is its portability and accessibility. 1. Enhanced Learning and Visualization
The (often referred to as the B737 "Pit" Companion) is primarily a technical deep-dive into the Boeing 737's systems. While its core purpose is professional training, it also serves as a vital resource for the "pilot lifestyle"—balancing technical mastery with the unique demands of life on the flight deck and during layovers. The "Pit Companion" as a Lifestyle Asset
The 737 cockpit is divided into several sections, including: Clear illustrations of system A, system B, and
The B737 Cockpit Companion is a comprehensive reference guide designed to bridge the gap between basic pilot knowledge and deep technical systems engineering. Unlike operator-specific manuals, this guide focuses on the "theory of operation"—explaining not just how a system works, but why it works that way. It provides:

Despite being a paid, third-party resource, it remains a gold standard in the aviation community because it translates dense engineering data into actionable pilot knowledge. (like the NG or MAX) or a detailed summary of a particular system, such as hydraulics or electrics?
The term “B737 Cockpit Companion” typically refers to a specific set of cockpit reference guides, most notably the or similar condensed system summary cards. These resources are designed to bridge the gap between dense airline flight manuals (FCOM) and the immediate memory requirements of a pilot in the cockpit.
