The fixed- wing aircraft’s superiority over helicopters for this important watchdog mission is partly a product of its “stealth”, resulting from a low noise signature and an ability to mix-in with the multitude of other fixed wing aircraft in the skies; and partly the re- sult of its smoothness and stability as a long- range stand-off FLIR and video platform. Soloy also offers an FAA-certified surveillance window, shown at left, along with an observer seat (the most comfortable in the market), and a recessed headliner with 4-point seatbelt upgrade.

Soloy’s Rolls-Royce Heritage In watching the Soloy Turbine 206 “Mark 2” take shape on the hangar floor, we realized that Soloy and the Rolls-Royce 250-series engines go back a long way. In the mid-70s, working with designer and initial manufacturer Detroit Diesel Allison divi- sion of General Motors, Soloy began a series of conversions with this enormously successful se- ries of light turbine engines. At the time, the en- gine was young, and going through the in-service development period leading to a powerplant that revolutionized the rotary wing industry. Soloy’s conversion process involves removal of the piston engine, propeller and accessories, and the Soloy’s involvement began with the conversion of installation of the Rolls-Royce 250-C20S turbine the Hiller UH12D/E helicopters, followed immedi- powerplant, together with a Hartzell or MT propeller. ately by the similar conversion of the Bell 47G.

This variation was called the Soloy Turbine Pac, and won certifica- tion in the Cessna 206 (now Soloy’s “ Mark 1”) and the Cessna 207. In what may be considered the most ambitious STC program of all time, Soloy and Tridair teamed to certify a twin-engined version of the Bell 206L-3 and 206L-4 Long Ranger. Twin- engine Soloy kits were purchased by Bell Heli- copter Textron and incorporated into their produc- tion line in Montreal.

BELL 206L Long Ranger with Rolls-Royce 250-C20R engine FLIGHT MANUAL SUPPLEMENT REVISION Soloy's recent revision to its Bell 206L Rolls- Royce 250-C20R Rotorcraft Flight Manual Supple- ment clarifies the method for calculating In-Ground Effect (IGE) and Out-of-Ground Effect (OGE) hover and rate of climb performance. As originally issued, the Soloy RFMS restricted performance to that obtained with a “min spec” C20B engine, and the torque limit placard - pub- lished in the LIMITATIONS section of the RFMS - Cessna 185 with Soloy Turbine Pac had the effect of precluding the use of available performance to limits already approved for the en- Other prototype applications included the Beech- hanced C20B-powered helicopter. craft T34 Mentor, Chilean airframe ENAER’s T35 Aucan, and the Groen Bros autogyro. Fully-certified Soloy engine conversion projects include the 250-B17 powered Beechcraft A36 Bonanza (now known as the Tradewind Turbine Propjet), the -C30 Eurocopter AS350D Allstar, the C20R Bell 206 Jet Ranger and Bell 206L Long Ranger. It’s an extensive list of achieve- ments, one now is extending into the future with the Rolls-Royce 250-B17F installation in the Cessna 206. May this relationship continue for many more mutually-successful years! For example, Bell offers an approved water / alco- hol performance kit for the C20B powered aircraft, and publishes data that permits improved perform- CALL - FOR SALE - CALL ance based on engine power check results.

Why have a placard at all? Because the C20R has extra power to allow 206L operations at higher weights and density altitudes than the original cer- tification envelope, authority to fully utilize avail- able C20R power would have required flight test of new static and dynamic structural loads, control travel margins, and determining tail rotor effective- ness. By placarding performance to a previously approved envelope, significant certification costs were realized, resulting in better performance value for the customer.
