P-750 XSTOL

An aircraft model that with its capabilities and performance, could surprise us, The P-750 XSTOL.  A not so widely known aircraft, such as cessna´s or piper´s. However, this plane has many things to offer because of its multi-disciplinary roles, applications and variants whether it is freighter, passengers, Spraying, Fire Fighting, and skydive operations.

The P-750 has the capability of take-off and landing within extremely short distances of runway, so the XSTOL (Extremely Short Take-Off and Landing) name is given to it. 244m or less is the distance that the aircraft needs to take off and land. In addition, the runway condition is not a limitation, it can operate in a semi-prepared airstrips and different terrains.

Pacific Aerospace, the manufacturer, decided to enhance the Cresco model for the skydiving community, and develop the program for a new utility aircraft, with STOL performance for freight, passenger, agricultural, photography. In 2004, the FAA certified the PAC 750XL (since renamed the P-750 XSTOL), after the modifications of the program, some parts of the Cresco remained. However, Wings, ailerons, flaps, fuel system, etc. have been either replaced or modified.

From the preliminary phase of the design to FAA certification, it took about 52 months. Devised to be used in skydive operations, other use is given to the aircraft, in several operations, one of them is aerial survey.

The versatility of the aircraft P-750 XSTOL is huge, it has a wide range of operational activities (aerospace.co.nz):

  • Sets the benchmark for 10-seater STOL utility aircraft.
  • Option of robust metal compartment lining with wall-mounted track for use with cargo nets and a partition located behind the pilot.
  • Ability to take a mixed load of passengers and freight on the same flight.
  • Able to carry seventeen skydivers or six tandem teams.
  • Can be readily customer-modified for geophysical survey work.
  • Able to carry a 4,888lb (2,272 kg) hopper.
  • Effectively operates off short, narrow farm air strips that are often situated on ridgelines.
