When the YOH-4A was eliminated by the Army, Bell went about marketing the aircraft. In addition to the image problem, the helicopter lacked cargo space and only provided cramped seating for three passengers. The solution was a redesigned fuselage, sleeker and aesthetically appealing, adding 16 ft 3 (0.45 m 3 ) of cargo space in the process. A Bell executive contributed to the redesign by drawing two lines on a sketch extending the fuselage to where it meets the tail. The redesign was designated Bell 206A, and Bell President Edwin J. Ducayet named it the JetRanger , denoting an evolution from the popular Model 47J Ranger .^[source]Bell 206 · Development / JetRanger; only the objects and conditions stated in this passage

The 206L LongRanger is a stretched variant with seating for seven. The fuselage, stretched a total of 30 inches (760 mm), adds two rear-facing seats between the front and rear seats. Since 1975, Bell has produced more than 1,700 LongRangers across all variants. In 1981, a military version, the 206L TexasRanger was released. The original 206L used an Allison 250 -C20R engine, and a series of model upgrades replaced this engine with more powerful versions; the 206L-1 used a 250-C28, and the 206L-3 and 206L-4 used the 250-C30P.^[source]Bell 206 · Development / LongRanger; only the objects and conditions stated in this passage

In both applications, the 250-C30P is derated from 650 hp for takeoff and 501 hp continuous. The 206L-3 is transmission-limited to 435 hp for take-off, and the 206L-4 is transmission-limited to 495 hp. The derating of the C30P produces an advantage in hot-day and high-altitude operations, as it can produce the rated horsepower at higher altitudes and temperatures where applications that use the maximum rating of the engine at sea level suffer accelerated performance deterioration with increases in temperature and altitude. The 206L-3 and L-4 have not been offered in a twin configuration under those model designations.^[source]Bell 206 · Development / LongRanger; only the objects and conditions stated in this passage

In 2007, Bell announced an upgrade program for the 206L-1 and 206L-3 designed to modify the aircraft to the 206L-4 configuration; modified aircraft are designated 206L-1+ and 206L-3+. Modifications include strengthened structural components (including a new tailboom), improved transmission, upgraded engine for the L-1, all of which result in a maximum gross weight increase of 300 pounds and increased performance.^[source]Bell 206 · Development / LongRanger; only the objects and conditions stated in this passage

The basic shape and design of the JetRanger remained unchanged since 1967, but Bell introduced the 206B JetRanger II in 1971. In 1977, the 206B-3 JetRanger III was introduced with its modified tail rotor and more powerful engine. The JetRanger is popular with news media for traffic and news reporting. The LongRanger is commonly used as an air ambulance and as a corporate transport. On September 1, 1982, pilots H. Ross Perot, Jr. and Jay Coburn departed Dallas, Texas in the " Spirit of Texas ", a Bell 206L-1 (N3911Z). They returned on 30 September, 29 days and 3 hours later, completing the first around-the-world helicopter flight.^[source]Bell 206 · Operational history; only the objects and conditions stated in this passage

On July 22, 1994, Ron Bower landed his 206B-3 (N206AJ) at Hurst, Texas , setting a new record for around-the-world flight by a helicopter. Bower had departed on June 24 and returned 24 days, 4 hours, 36 minutes and 24 seconds later, averaging 35.62 knots (40.99 mph; 65.97 km/h). Bower had added a 91-US-gallon (340 L) auxiliary fuel tank, which doubled the JetRanger III's range.^[source]Bell 206 · Operational history; only the objects and conditions stated in this passage

The HH-65 Dolphin is used for homeland security patrols, cargo , drug interdiction , ice breaking , military readiness, pollution control , and search and rescue missions. The HH-65 is known for its Fenestron tail rotor and its autopilot capabilities, which can complete an unaided approach to the water and bring the aircraft into a stable 50 ft (15 m) hover, or automatically fly search patterns, an ability which allows the crew to engage in other tasks.^[source]Eurocopter MH-65 Dolphin · Development; only the objects and conditions stated in this passage

The HH-65A's minimum equipment requirements exceeded anything previously packaged into a helicopter weighing less than 10,000 pounds (4,535 kg). Seventy-five percent of the HH-65's structure—including rotorhead, rotor blades and fuselage—consists of corrosion-resistant composite materials.^[source]Eurocopter MH-65 Dolphin · Design; only the objects and conditions stated in this passage

Also a unique feature of the Dolphin is its computerized flight management system, which integrates state-of-the-art communications and navigation equipment. This system provides automatic flight control. At the pilot's direction, the system will bring the aircraft to a stable hover 50 feet (15 m) above a selected object. This is an important safety feature in darkness or inclement weather. Selected search patterns can be flown automatically, freeing the pilot and copilot to concentrate on sighting & searching the object.^[source]Eurocopter MH-65 Dolphin · Design; only the objects and conditions stated in this passage
