What came to be known as the A model (206) was originally designed in April 1965, with the first flight taking place on 10th January 1966. By January 1967 it was in full production and had sold over 7500 by 1989, rightly claiming to be the most popular light turbine helicopter in history, having done millions of flight hours. In fact, the 206 is officially the safest single-engined aircraft, including fixed wing, according to NTSB statistics. Various non-standard versions have appeared from time to time—for example, the US Army and Navy had their own, as did the Australian Army. The JetRanger II (206B) came on the scene in 1972, and the III not long after. The 206L came last. In practical terms, the 206 is roughly equivalent to a Chevy truck, in that it does lots of things fairly well, but there are better machines for specific tasks, mainly because any improvements made over the years have not included the payload – there’s about 300 lbs less available now than originally (well, you can't do much else with the rotor system). Thus, there are advantages to choosing older models; for example, the engine start cycles aren't limited on a 206A, which makes it ideal for situations where you might want to start the engine often. It also uses less fuel, but may have less Max All Up Weight. The MAUW of the B and up is 3200 lbs, which is considerably lighter than the average quality car, and a typical APS (Aircraft Prepared for Service) weight is about 2000 lbs, so you have slightly more than 1000 lbs for fuel and passengers, and 150 lbs more if you use the hook, so, on full tanks, you can get three average male passengers in and fly them around for about 2 hours. With the range extender fitted, you lose a passenger but get an extra half hours' endurance. To use the rear seats for cargo, just remove the cushions. The ambulance version can hold two stretchers through a special large door, and there are Electronic News Gathering (ENG) variations as well, but these require special modifications to the airframe. . . .
