Cessna 150J Model Reference

Generation and Certification

The performance records below and the family dimensions reference retain their own year and source conditions. They can support comparison with the earlier swept-tail models, but a published cruise or climb result cannot diagnose an individual engine or establish the aircraft's present configuration. Electrical, engine and propeller records must be reconciled separately.

The 1969 150J chronology describes modernization of the controls and electrical switchgear. That is useful cockpit history, but it is not a complete serialized wiring instruction. The J follows the H and precedes the K without changing the basic O-200-A engine family or the standard 1,600-lb landplane limit. Its year summary gives 32 ft 8.5 in span, 23 ft length and 8 ft 7.5 in height. Those dimensions provide a better comparison with the later L-series length changes than a broad claim that all swept-tail 150s are dimensionally identical.

Serial Numbers and Production

For 150J, the ordinary source assignments are 1969: 15069309 through 15071128. The serial guide retains source conflicts and exceptional identities alongside these intervals.

Engine, Propeller and Equipment Changes

A J-model cockpit may now contain replacement switches, radios or instruments that differ from the historical panel description. For electrical research, identify the installed equipment and the applicable maintenance documentation before turning that description into a component assumption. The propeller applications also retain landplane/seaplane conditions, and the loading evidence contains both configurations. That means the ordinary serial establishes the J identity but cannot alone select a float-related propeller or a sea loading limit. The aircraft's configuration records complete the relationship that the model label only starts.

The 150J factory installation groups specify 1969: O-200-A, 100 hp at 2750 RPM. Its named propeller applications are 69CK family / 1A100/MCM6950 / 1A101/DCM6950; 1A90/CF. Their diameter, static-RPM and configuration conditions are preserved together below.

Specifications, Fuel and Loading

The 1969 performance series includes condition-preserved range entries in addition to cruise, climb and runway headlines. A high range figure should be read with usable fuel, altitude and the no-reserve basis rather than compared directly with a later figure in nautical miles or with a reserve. The 975-lb Standard and 1,060-lb Commuter empty-weight examples further explain why payload descriptions can differ within the same year. The useful buying comparison is the actual aircraft's load margin and documented equipment, not a single representative empty weight copied from a J-model summary.

The J's 1969 handbook family provides a bridge between its historical cockpit description and the numerical operating evidence. The electrical-switchgear wording should not be interpreted as an exact parts change at the first J serial unless the relevant source establishes that trigger. Its ordinary identity interval is nevertheless precise and distinct from the preceding H and following K. The later K spinner breakpoint is not a J change, and the later L gear generation is not a J feature by default. This separates model history from component effectivity and keeps a comparison of surviving aircraft focused on their actual installations.

Performance and Comparison Conditions

One published 150J example is 1969 cruise speed: 117 mph (power % 75; altitude ft 7000). The table keeps each metric's year, units, power, altitude, fuel and reserve columns together. Use the performance guide to distinguish headline comparisons from handbook operating calculations; no unreported condition is supplied for 150J.

Manuals, Maintenance and Research

D624-13 is the J-model manual lead, and its source retains the no-adjacent-year-borrowing boundary. A G, H or K manual may look familiar while failing to establish the right operating relationship. The corresponding Reims F150J shares a handbook-family mapping but has its own serial format and authority context. For a standard U.S. J, use the model's own serial interval and exact propeller/weight groups, then investigate seat locking, tail attachment and other maintenance topics through their named applicability rather than treating the family issue list as a diagnosis of every J airframe. The positive 150J publication leads are 1969: D624-13 (Owner's Manual).
