Short Takeoff and Landings (STOL)

One of the C-27J's key technical differentiators is its ability to land on short runways (STOL, Short Takeoff and Landings) and on unpaved runways — essential characteristics for performing successful missions across Canada's vast and rough terrain in sometimes harsh weather conditions.

The C-27J can land on almost any surface — snow, sand, and soft soil below CBR 4 (California Bearing Ratio is one of the most widely used methods for measuring load-bearing structure of unprepared airstrips and the soil underneath it). Additionally, it is capable of taking off from and landing on unprepared airstrips less than 500 meters long-a significantly shorter distance than other competitors in its class. Moreover, the aircraft has the best ground manoeuvrability compared with other military transport aircraft, a quality that enables the C-27J to access to a larger number of airfields and airstrips around the country. The minimum strip width for ground inversion 12.1 m.

There are several unique system features that enable the C-27J's outstanding STOL capability. First, the aircraft is equipped with landing gear and a brake system that are optimized for unprepared airstrips. Secondly, the aerodynamic design dimensions of the aircraft and advanced on-board avionics enable crews to optimize the flight profile in approach and in takeoff.

The C-27J has C-27J has a climb rate comparable to a 4 engine aircraft (C-130J) and its time to climb up to 10,000 ft is just 6 min.

In approach the aircraft has the best steep descent capabilities compared with other military transport aircraft (4,000 ft/min), Its 14 cockpit windows making better visibility for the pilots while competitor pilot’s external visibility don’t allow steep approach and manouvering

Additionally, the absence of specific design limitations as well as the aircraft's powerful engines, enable it to perform steep takeoffs and landings. Essentially, the C-27J can begin rotating/climbing immediately without any restrictions or fear of touching the tail. At takeoff, other aircraft in the class can start their rotation/climb only after flying at a level height, a few meters off the ground, which increases the necessary airfield length.

The C-27J's unparalleled abilities to perform short take-offs and landings (STOL) on unprepared surfaces are two important characteristics making it the best platform for Canada's FWSAR program.
