The B737 Cockpit Companion is a highly respected, practical reference guide designed specifically for pilots flying the Boeing 737 series. Originally created by veteran pilot Bill Bulfer, this guide simplifies the massive, dense technical text found in official Boeing Flight Crew Operations Manuals (FCOM) and Quick Reference Handbooks (QRH).
As aviation moves further into the digital age, the has largely replaced the traditional, thick physical books. Here’s why the PDF version is preferred: 1. Instant Accessibility (EFB Integration)
The electrical system on the 737 is notorious for its complexity, particularly the transfer of power between the Integrated Drive Generators (IDGs), the Auxiliary Power Unit (APU), and external power. The manual uses clear, color-coded flowcharts to show exactly what happens when a generator fails and how power is automatically rerouted.

The B737 Cockpit Companion is a specialized, highly respected reference manual designed for airline pilots, simulator instructors, and aviation enthusiasts. Unlike standard airline Flight Crew Operating Manuals (FCOM), which can be dry and purely procedural, Captain Bill Bulfer’s guide focuses on . Key Features of the Guide
Quick-reference guides to locate specific CBs across the flight deck panels. The B737 Cockpit Companion is a highly respected,
Focuses heavily on the transition from analog gauges to early Electronic Flight Instrument Systems (EFIS).
When studying the fuel or hydraulic systems, use a stylus on your tablet to trace the flow of fluids and electrical power within the PDF. Visualizing the routing helps retain the information far better than rote memorization. Here’s why the PDF version is preferred: 1
Using Ctrl+F (or Cmd+F), pilots can instantly type in a fault light or system name (e.g., "STANDBY POWER") and jump directly to the relevant page during intense study sessions.
The Cockpit Companion is (like an SOP or QRH). Instead, it is a deep-dive systems book designed to teach pilots "how the airplane is built" and "how the systems work," focusing on "theory of operation" rather than just the "need to know" philosophy of modern training.

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:
