Dec 30, 2014 I have a B200 Kingair with Sperry SPZ200 running a G600 Garmin Panel with no problems. The key to it is the GAD-43E interface and the setup by your technician. I will say though that if you have the spare dollars a digital autopilot would be good to have with the G600 as you will get more features like Alt pre select. 1953 Bell Helicopter 47D-1 Erection & Maintenance Manual.

Lawrence Burst Sperry (21 December 1892, Chicago, Illinois, United States – December 13, 1923, English Channel) was an aviation pioneer.
Biography[edit]
He was the third son of the gyrocompass co-inventor, Elmer Ambrose Sperry and his wife Zula.[1] Sperry invented the first autopilot, which he demonstrated with startling success in France in 1914. Sperry is also credited with developing the artificial horizon still used on most aircraft in the early 21st century.[2]
In 1918 he married film actress Winifred Allen, and Flying magazine reported that they were 'the first couple to take an aerial honeymoon' after they flew from Amityville to Governors Island.[3]
On 13 December 1923 Sperry took off amid fog in a Verville-Sperry M-1 Messenger from the United Kingdom headed for France but never reached his destination.[4] His body was found in the English Channel on 11 January 1924.
Legacy[edit]
A website using the name Mile High Club regards the 'Club's' 'founder' as pilot and design engineer Lawrence Sperry,[5] along with 'socialite Mrs. Waldo Peirce' (Dorothy Rice Sims)[6] citing their flight in an autopilot-equipped Curtiss Flying Boat near New York in November 1916.[7][8][9]

Why, Mrs Peirce and I didn't have what you might dignify by calling a real accident. It was only a trivial mishap. We decided to land on the water and came down perfectly from a height of 600 feet and would have made a perfect landing had not the hull of our machine struck one of the stakes that dot the water, which staved a hole in it.[8]
In 1979, Sperry was inducted into the International Air & Space Hall of Fame at the San Diego Air & Space Museum.[10]
Sperry was inducted into the Naval Aviation Hall of Honor at the National Naval Aviation Museum in Pensacola, Florida, in 1992.

The Bell 212 (also known as the Twin Two-Twelve) is a two-blade, twin-engine, medium helicopter that first flew in 1968. Originally manufactured by Bell Helicopter in Fort Worth, Texas, United States, production was moved to Mirabel, Quebec, Canada in 1988, along with all Bell commercial helicopter production after that plant opened in 1986.[2][3]
The 212 is marketed to civilian operators and has a fifteen-seat configuration, with one pilot and fourteen passengers. In cargo configuration the 212 has an internal capacity of 220 ft3 (6.23 m3). An external load of up to 5,000 lb (2,268 kg) can be carried.

Development[edit]
Based on the stretched fuselage Bell 205, the Bell 212 was originally developed for the Canadian Forces as the CUH-1N and later redesignated as the CH-135. The Canadian Forces took delivery of 50 starting in May 1971. At the same time the United States military services ordered 294 Bell 212s under the designation UH-1N.
German Bell 212 used as air ambulance by the Ministry of the Interior.
By 1971, the 212 had been developed for commercial applications. Among the earliest uses of the 212 in civil aviation was by Helicopter Service AS of Norway to be used in support of offshore oil rigs. Today the 212 can be found used in logging operations, maritime rescue and resupply in the Arctic on the Distant Early Warning Line or North Warning System.
The 212's main rotor is powered by a Pratt & Whitney Canada PT6T-3 Twin-Pac made up of two coupled PT6 power turbines driving a common gearbox. They are capable of producing up to 1,800 shp (1,342 kW). Should one engine fail the remaining engine can deliver 900 shp (671 kW) for 30 minutes, or 765 shp (571 kW) continuously, enabling the 212 to maintain cruise performance at maximum weight.
Early 212s configured with an Instrument Flight Rules (IFR) instrument package were required to have a large and very obvious fin attached to the roof of the aircraft, above and slightly behind the cockpit. This fin was initially determined necessary to alter the turning performance of the aircraft during complex instrument flight maneuvers, but is no longer required due to revised stipulations of the type certificate. Many aircraft still fly with the modification.
In 1979, with the purchase of eight by the Civil Air Authority, the 212 became the first U.S. helicopter sold in the People's Republic of China.
The ICAO designator for this aircraft as used in a flight plan is 'B212'. Bell developed the Model 212 further with the Bell 412; the major difference being the composite four-blade main rotor. The last Bell 212 was delivered in 1998.[1]
