The development of P-750 XL began in 2000. The maiden flight took place in 2001. The aircraft was accredited with the US Federal Aviation Administration (FAA) certification in March 2004 and renamed as P-750 XSTOL.
The aircraft was showcased at the African Aerospace and Defence (AAD) Expo 2008 held at Ysterplaat Air Force Base.
Pacific Aerospace signed an agreement with InterGlobe General Aviation in April 2010 to be an exclusive seller of P-750 XSTOL aircraft in India, Sri Lanka, Bangladesh and the Maldives.
About 66 P-750 XSTOLs were produced by May 2010.
Orders and deliveries of the PAC P-750
About 50 P-750 XSTOL orders were received by 2008. The customer orders include New Zealand (13), North / South America (16), Europe (nine), Africa (nine), South East Asia (12) and Central Asia (two).
The US imported 12 P-750 XSTOLs for skydiving missions as of July 2009.
Design
The P-750 XSTOL is of low wing monoplane design and can operate both day and night even on semi-prepared airstrips and grass or dirt runways. The aircraft is built by extending the fuselage and modifying the tail section of PAC Cresco.
It can execute agricultural spraying, fire fighting, sky diving, passenger and freight transport and aerial photography missions. It can also be deployed for geo-survey work by incorporating a magnetic anomaly detector.
P-750 XSTOL features
The P-750 XSTOL features a fixed tricycle type landing gear, oleo pneumatic shock absorbers, electro-magnetic interference (EMI), a large double door, flaps, ailerons and elevators. It is fitted with a 2,272kg capacity chemical hopper at the rear fuselage when operated as agricultural sprayer.
Flight deck
The glass cockpit of P-750 XSTOL accommodates a pilot. The all round glass canopy of the aircraft renders clear visibility. The cockpit is equipped with Garmin 430/530 avionics suite which includes four-inch and five-inch colour displays, moving map displays, voice over recorder, instrument landing systems and GDL-49 lightening detection and traffic.
Other systems installed are autopilot, weather radar, air speed indicator, distance measuring equipment, 14V or 28V electrical systems, global positioning system and electronic flight instrumentation system.
Cabin
The P-750 XSTOL features a 240ft3 cabin with plenty of leg space for passengers. It is fitted with four doors and can accommodate nine passengers or 17 parachutists.
The cabin can be easily reconfigured for different roles by removing the passenger seats. It also features a 70ft3 centreline cargo pod, an 18ft3 baggage compartment and large windows to provide clear outside views to the passengers.
The door sill height of the cabin is 1.1m. The length and widths are 5.3m and 1.28m respectively. The height is 1.38m.
Engines
The P-750 XSTOL is powered by a single PT6A-34 turboprop engine rated at 560kW of output power. The engine is designed and developed by Pratt & Whitney Canada of the US.
It is fitted with a Hartzell three-bladed constant speed, full feathering and reversible propeller which can rotate at the rate of 2,200rpm for short field performance.
The diameter and tip clearance of the propeller are 2.43m and 0.48m respectively.
The engine is also incorporated with an epicyclic speed diminution gearbox to minimise propeller noise by optimising the output speed. It is equipped with a multistage axial, a single-stage centrifugal compressor, a reverse flow combustor and a single-stage compressor turbine.
The engine is 1.57m long and of 0.48m diameter.
Performance
The P-750 XSTOL can climb at the rate of 5.4m/s. The maximum and cruise speeds of the aircraft are 315km/h and 259km/h respectively. The stall speed is 107km/h. The range and service ceiling are 1,079km and 6,096m respectively. The maximum endurance is five hours.
