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:
The PDF format makes it searchable, zoomable on an iPad (ForeFlight, EasyVFR), or printable for laminating and binding into a kneeboard.
As the industry digitizes, the static "PDF" is being replaced by more sophisticated tools:
It is vital to note that the B737 Cockpit Companion is a study aid, not an official approved document. It is considered "grey literature" in the aviation community—highly accurate and respected, but not a replacement for the aircraft's approved Flight Manual (AFM) or the company's specific FCOM.
Pilots should always cross-reference the Companion with their airline's approved manuals, as system modifications and procedures can vary between different operators and specific aircraft line numbers.
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.
