Manufacturer-published distances at sea level, ISA and reference weight. Not corrected for altitude, temperature, wind or runway condition, takeoff included. Uses the declared LDA as a proxy for effective runway length (RBAC 135.361) and the most favourable threshold in calm air (135.385(b)(1)): on the day, wind may force the shorter threshold. Destination only: does not assess the alternate aerodrome (135.387). Not a substitute for the AFM or the operator's performance analysis. Rule: RBAC 135.385 and 135.398; private flying (RBAC 91) is not factored. Runways: declared distance (LDA) from AISWEB/DECEA (2026-09-05), checkable on each aerodrome chart; where DECEA publishes no declared distance, physical length from OurAirports is used.

History

  1. 1971FAA certification
  2. 1973 - Lineage since 1948, Ted Smith design of the Aero Commander 500

    The Aero/Twin Commander lineage began in 1948 with the Aero Commander 520, a design by engineer Ted Smith (who later created the Aerostar 600). The piston version ran through the Aero Commander 500/560/680 in the 1950s-60s, and turbine conversion arrived in 1964 with the Turbo Commander 680T. The 690 was launched in 1971 under Rockwell with an updated Garrett TPE331-5 engine and a refined fuselage, and was the most commercially successful turboprop of the family. More than 500 units of the 690 variants (690, 690A, 690B) were produced.

Curiosities and highlights

Benefits

High-wing configuration delivers superior cabin visibility

Unlike the competition (King Air, Conquest II) with a low wing, the Twin Commander 690 keeps Ted Smith's high-wing design with engine nacelles above the fuselage. This delivers panoramic visibility for passengers at the side windows (no wing cutting the view), eases access to the forward baggage compartment and creates an executive silhouette recognizable from a distance. Nostalgic operators and collector owners value this unique visual identity.

285 kt cruise places the 690 among the fastest turboprops of the 1970-80s era

The 717 SHP Garrett TPE331-5s deliver 285 kt in high cruise, comparable to the King Air B100 and superior to the Cessna Conquest I (245 kt). With a range of 1,230 nm it is capable of continental executive missions in the US and regional ones in Latin America. The initial rate of climb of 2,820 fpm is particularly high for the category.

Notable operators included presidents, executives and celebrities

The Aero/Twin Commander built a reputation among senior executives and world leaders. US President Dwight D. Eisenhower used the Aero Commander 560A as an executive aircraft during his term (1953-61). Notable figures such as Bob Hoover (renowned demonstration pilot) and several Fortune 500 corporations kept dedicated fleets. This historical heritage keeps the model's appeal among enthusiast owners.

Limitations

Production ended and support concentrated in specialized hubs

Production of the 690 ended decades ago. Today Twin Commander Aircraft Corporation (Creedmoor, NC) operates only as a support and parts provider, with no new production. Support for the Garrett TPE331-5 depends on authorized Honeywell centers, and the remaining units are 40+ years old, requiring a complete avionics retrofit (USD 150-200k) for current operation with ADS-B Out, GPS WAAS and PBN.

Curiosities

Jetprop 840/900/980 variants introduced incremental power improvements

The 690 lineage evolved into the Jetprop 840 (1979, TPE331-5), Jetprop 900 (1981, higher MTOW) and Jetprop 980/1000 (1979-86, TPE331-10 with 1,000 SHP) variants. Although production of the base 690 ended earlier, the Jetprop variants continued to be delivered under the Gulfstream Commander brand (after Rockwell sold the division in 1981) until 1986. Some of these top-end variants reach 290 kt cruise, competing directly with the King Air 350.
