"WESTWIND 2 Private Jet, Information!"

The ten-passenger Westwind I was produced in 1972 with a stretched fuselage. In 1980, IAI announced a second go-around, the Westwind II, with redesigned wings and the addition of winglets.


The Westwind II’s winglets are its most notable improvement. Positioned atop the tiptanks (while most aircraft substitute one for the other).


The usual winglet design was proven to be more effective and improved the lift-to-drag ratio.


Another improvement the Westwind II has over its predecessor is what IAI refers to as its Sigma wing, a recontoured wing that holds 1.5 more fuel.


This allows for a higher takeoff weight (500 additional pounds to 23,500 lbs); reaches a 2,000 feet higher initial cruise range; and increases range by five percent.


Due to these modifications, the Westwind II enjoys greater operating weights and improved hot-and-high performance evidenced by the aforementioned numbers.


The Westwind II is powered by two Honeywell TFE731-3-1G turbofan engines, the same as its predecessor.


Each engine is rated 3,700 lbs of thrust and the inspection interval is 4,200 hours.


Typically, the Westwind II’s cockpit would be equipped with the Collins FMS90 flight management system


The cabin is relatively small but features a divan, common in larger, executive-class business jets.


The Westwind II is capable of accommodating seven passengers in a four seat club and a three-seat, side-facing divan.


Across from the divan is a galley/refreshment center. A full-width lavatory is also a cabin feature.


The cabin measures 4.9 feet high, 4.8 feet wide and 15.9 feet long.


The Westwind II remains a viable option in the medium-range private jet category.


Its air frame makeover is accountable for major performance improvements over its predecessor.


You can still find the Westwind II for sale or to charter. Because its design is so distinguishable, you’ll know it when you see it.


The Westwind has found a niche in the aero-medical market because of its low door.


This facilitates easy patient loading, and spacious cabin, but more importantly because of its price and range.


You can buy a mid-1980s model for less than $1 million and many of these are fitted with auxiliary fuel tanks that can boost range to 2,900 nautical miles.


That makes the Westwind the only light jet that can cross the Atlantic or the continental U.S. without refueling.


And its cabin is more spacious because of its ovoid, as opposed to oval, fuselage shape. There's more head-and-shoulder room than in a Citation or a Learjet.


The Westwind has other advantages, including a baggage compartment that can hold nearly 1,000 pounds, and good short-field landing capability.
