Convair 880 (Model 22 / 22M) — Flight, Operations & Maintenance Manuals Collection
The Convair 880 remains one of the most technically fascinating commercial jetliners ever built. Engineered by the Convair Division of General Dynamics in San Diego and custom-built to prioritize outright cruise speed (Mach 0.88) over passenger capacity, the 880 was the fastest subsonic commercial transport of its era — and one of the most commercially ill-fated. Only 65 were built. Today, none fly.
This living collection brings together five surviving original primary-source documents covering the 880's operational, maintenance, and commercial history — from the factory Operation Manual to a Trans World Airlines operator Flight Handbook, the full Maintenance Manual, the Illustrated Parts Catalog, and the original 880/600 sales brochure.

Aerodynamic Design & Wing Geometry
The 880's aerodynamic profile inherited heavy design influences from Convair's extensive military delta-wing experience. The wing features a 35-degree sweep at quarter-chord, optimized to push the critical Mach number beyond contemporary platforms. The baseline Model 22 used a clean wing without leading-edge high-lift devices — highly efficient at cruise but demanding extreme runway lengths. Control authority relied on servo-tab deflected ailerons, mid-wing spoilers for roll assist, and trailing-edge Fowler flaps. The deliberately narrow five-abreast cabin cross-section minimized forward aerodynamic drag, contributing directly to the aircraft's exceptional cruise performance.
Performance Data — Model 22 vs. 22M
- MTOW: 184,500 lbs (Model 22) / 193,000 lbs (22M)
- Maximum cruise speed: Mach 0.88 — 615 mph (990 km/h) — both variants
- Service ceiling: 41,000 ft
- Take-off field length: approx. 8,750 ft (Model 22) / approx. 7,550 ft (22M)
- Max range: 2,470 nm (Model 22) / 2,500 nm (22M)
- Usable fuel capacity: 10,584 US gal (Model 22) / 12,538 US gal (22M)
Powerplant — General Electric CJ805-3
The CJ805-3 turbojet was a direct civilian, non-afterburning derivative of the military J79. It produced 11,200 lbf of dry static thrust per engine, upgraded to 11,650 lbf on the CJ805-3B for the 22M variant. The engine's military pedigree delivered blistering performance but also its commercial undoing: intense black smoke plumes, severe acoustic footprints, and high specific fuel consumption created prohibitive seat-mile economics that no operator could sustain against the Boeing 707 and Douglas DC-8.
Handling, Stability & Flight Controls
Flight crews universally praised the 880 for sports-car-like manual handling at high velocities. The trade-off was severe at low speed: without leading-edge slats, the original model demanded high approach speeds (139 knots) and unforgiving stall margins. The 22M addressed this with four leading-edge slats per wing and Kruger flaps, reducing take-off field length and improving stall margins significantly. Active electronic yaw damper scheduling was required to prevent Dutch roll anomalies identified in six-degree-of-freedom perturbation testing.
Key Engineering Bulletins
Service history produced recurring bulletins on three primary issues: anti-skid braking evolution (from mechanical to high-response electronic inertia-actuated systems), integral wing fuel tank corrosion from microbial contamination, and hydraulic system redundancy protocols for the high-pressure spoiler actuators in single-engine-out events.
⚠️ Regulatory Notice: Under FAA 14 CFR § 43.13 and EASA Part-M, any mechanic performing maintenance on an active aircraft must use current, manufacturer-approved revision-controlled data. This archival document does not satisfy that requirement.
This is an archival, static-copy edition fixed at its original publication date. Intended for historical reference, flight simulation, museum restoration, and educational use only. Not approved for active airworthiness maintenance under FAA 14 CFR § 43.13, EASA Part-M, or equivalent international regulations. Operators of active aircraft must use current, revision-controlled publications from the Type Certificate holder or an authorized distributor.
