The B737 Cockpit Companion: An Essential Guide for the Modern Aviator

In the world of commercial aviation, few airframes carry the legacy or ubiquity of the Boeing 737. From the "Jurassic" -100 series to the cutting-edge MAX, the aircraft has evolved significantly. For pilots transitioning to the type, or seasoned veterans looking to deepen their systems knowledge, official manuals often present a daunting wall of technical data. This is where the B737 Cockpit Companion has cemented its status as an industry standard.

What is a "B737 Cockpit Companion PDF"?

A B737 Cockpit Companion PDF is a condensed, printable (or tablet-ready) digital document that distills the entire Boeing 737 Flight Crew Operations Manual (FCOM) and Quick Reference Handbook (QRH) into a 15–30 page "cheat sheet."

Unlike the full FCOM (which runs over 2,000 pages), the Companion focuses exclusively on:

Cockpit panel layouts (Overhead, MIP, Pedestal, After Glare shield).
Normal flows (Before Start, After Start, Taxi, Before Takeoff, Climb, Cruise, Descent, Approach, Landing, Shutdown).
Memory items (Engine Fire, Cabin Altitude Warning, Runaway Stabilizer, etc.).
Performance tables (Quickly thumbing to V-speeds and derate settings).
Limitations (Max crosswind, max flap extension altitude, red line speeds).

The PDF format makes it searchable, zoomable on an iPad (ForeFlight, EasyVFR), or printable for laminating and binding into a kneeboard.

Key Features of the Guide

The strength of the Companion lies in its layout and accessibility. Unlike standard manuals that are organized by chapters or ATA codes, the Companion often organizes information by cockpit panel location. This allows a pilot to look at a specific section of the overhead panel, pedestal, or main instrument panel and instantly understand the associated systems and limitations.

Key elements typically include:

Systems Summaries: Simplified explanations of hydraulic, electrical, fuel, and pneumatic systems.
Switchology: Detailed breakdowns of what every switch, light, and indicator does—often including the "normal" positions for various phases of flight.
Limitations & Memory Items: Quick-reference tables for critical speeds, V-speeds, and memory item checklists.
Schematics: Visual flowcharts that make system logic (such as fuel crossfeed or bleed air routing) easier to comprehend.

Passenger Information Terminal (PIT)

The Passenger Information Terminal (PIT) or more commonly referred to in the context of in-flight entertainment and passenger services, relates to systems or terminals used to provide information and entertainment to passengers during their flight. This can include in-flight entertainment (IFE) systems, passenger service units (PSUs), and digital displays providing flight information, entertainment, and other services.

Common Mistakes to Avoid with the PDF Companion

Mistake 1: Using a 737-800 PDF for a 737-900ER. The -900ER has different tailstrike margins and door limitations.
Mistake 2: Relying only on the PDF for checklist completion. The companion is a reminder, not a substitute for the approved QRH.
Mistake 3: Forgetting that the MAX has a different engine start procedure (waiting for N2 25% for LEAP vs. 16% for CFM).
Mistake 4: Not updating the PDF. Boeing issues FCOM bulletins every quarter. If your PDF is from 2018, the Runaway Stabilizer procedure has changed.

1. Product Identification and Content Analysis

The "B737 Cockpit Companion" is not an official Boeing publication. It is a third-party study aid. The most recognized version is a folded, laminated card or booklet that fits on a pilot’s kneeboard or in a flight bag.

Key Features of the Resource:

System Summaries: It condenses the Boeing 737 Flight Crew Operations Manual (FCOM) into bullet points. It typically covers major systems such as:
- Fuel System
- Hydraulic System
- Electrical System
- Pneumatics and Air Conditioning
- Flight Controls
Limitations: A core component is the consolidation of "V-speeds" and limitation numbers (e.g., maximum altitudes, flap extension speeds, maximum tire speeds).
Flows and Checklists: It often includes non-normal checklist flow patterns or memory items, serving as a quick reference for recurrent training or oral exams.
Format: Physically, it is often a trifold or multi-panel laminated card. Digitally (PDF), it is a scanned or vector-based document optimized for tablets.

Distinction from Similar Products: While Pat Boone’s "Cockpit Companion" is the namesake, the term is often colloquially used to refer to similar products like:

Flight Companion / Cockpit Series: Other publishers produce similar laminated cards.
"Gouge" Guides: Unofficial notes passed between students.

Conclusion: Your Call to Action

The B737 Cockpit Companion PDF is more than just a file—it is a training philosophy. It forces you to prioritize what matters: the 20% of knowledge that covers 80% of flight operations.

Whether you are a real-world First Officer upgrading to Captain, a sim pilot flying the PMDG 737 across VATSIM, or a student mechanic learning the pneumatic system, having a well-organized, variant-specific, current PDF companion will save you hours of frustration and potentially thousands of dollars in simulator retraining fees.
