The Hawker 800 series has been rapidly adding new members since it was initially certified. The Hawker 800XP, a revision of the Hawker 800 with different engines and avionics, soon became the Hawker 850XP, a virtually identical model with winglets. After a successful track record of reliability, high performance, and consistent sales, the $13.775 million Hawker 850XP is being replaced by two close relatives, the entry-level Hawker 750 and the Hawker 900XP. The Hawker 750 will share the same engines, cabin, and major systems as the 850XP but will lose the winglets and a ventral fuel tank. These two alterations result in a significant weight reduction, which in turn impacts the Hawker 750’s performance enough to set it apart from its predecessor.
The cabin of the Hawker 750 is identical to the cabin of the Hawker 850XP: the design and dimensions are unchanged. The high-density 15 passenger layout available to buyers of the Hawker 850XP is no longer available; only the more commonly selected 8 passenger layout is offered. The Hawker 750’s cabin outdoes the Hawker 850XP’s cabin in baggage space since the Hawker 850XP’s ventral fuel tank was replaced by a baggage compartment in the Hawker 750. Between internal and external compartments, the Hawker 750 has a total of 79 cubic feet of baggage space; the Hawker 850XP has only 50 cubic feet available in an internal compartment.
The Hawker 750 uses the same TFE731-5BR engines as the 850XP, but performs significantly better on the runway due to its reduced weight. On a standard (59°F) day at sea level, the Hawker 750 can take off in 4,696 feet – 336 feet less than its counterpart would require. At an altitude of 5,000 feet and a temperature of 71°F, the 750’s runway requirements would increase to 7,094 feet – still 924 feet under the Hawker 850XP’s takeoff distance.
The tradeoff for the Hawker 750’s improved runway performance is its reduced fuel capacity: the 750’s fuel capacity is 8,500 pounds, and the 850XP’s capacity is 10,000 pounds. Although the Hawker 750’s range takes a hit, the loss in fuel is somewhat balanced out by its lighter load. The 750’s NBAA IFR range with four passengers is 2,163 nautical miles, 513 nautical miles under the Hawker 850XP’s range. The difference in range becomes more apparent when both jets are loaded with their maximum payload and required reserves: the Hawker 750 can fly 1,978 nautical miles, and the Hawker 900XP can fly 2,394 nautical miles.
So far some combination of the Hawker 750’s cruise speed, runway performance, range, and asking price has proven to be highly appealing to buyers, including NetJets, which placed an order for 30 Hawker 750s. Deliveries for the $11.95 million private jet are expected to begin in the third quarter of 2007.
