Boeing 737 Family
The Boeing 737 Family is a twin-engine, single-aisle transport platform developed for shorter routes than Boeing's early four-engine jetliners. The first 737 flew in 1967, and the design subsequently evolved through the original, Classic, Next Generation, and MAX series. Passenger, convertible-freighter, dedicated freighter-conversion, and Boeing Business Jet versions share the broader 737 lineage, while their dimensions, capacity, range, and propulsion differ substantially by series.

- Boeing 737NG planning data identify CFM56-7B24/-7B26/-7B27 engines; this exact canonical CFM56-7B variant now replaces the prior family-level placeholder.
- Name
- 737-800 CFM56-7B option
- Notes
- This records the exact CFM56-7B installation documented for the 737-800 portion of the broad 737 family. CFM56-3B, other CFM56-7B subratings, and 737 MAX LEAP-1B remain unmodeled here.

- Two CFM56-family engines for the Boeing 737 Classic branch; source context is CFM56-3/3B, but no exact cfm56-3b canonical node exists.
- Name
- 737 Classic CFM56 family option
- Notes
- CFM identifies the CFM56-3 as the sole-source powerplant for Boeing 737 Classic -300/-400/-500 aircraft; the exact cfm56-3b identity is absent from the current propulsion schema, so this relationship remains explicitly family-level.
