R/STOL Hi-Lift Systems work full time at short, back-country airstrips or at the busiest metropolitan airports. R/STOL's improvement performance gains extra time and reduces wear and tear on your aircraft to cut your cost of operation.
Benefits include:
Shorter take-off and landing distances (as much as 50% reduction on some models) are realized as a result of the increased efficiency and lifting ability of the wing.
A substantially increased safety margin can be realized by operating your aircraft at the old performance figures. This benefit is best appreciated when flying in gusty conditions or flying through wind shear.
Slower speeds near the ground at takeoff and landing due to the full-flap system. In and engine out emergency, slower speeds and added controllability reduce impact effects.
Sharp, crisp control at slower speeds and into the stall due to stall fences and aileron gap seals.
Takeoff with reduced power (75%) eliminates the need to reduce power immediately after takeoff. This not only preserves your engine but reduces the chance of engine failure after takeoff. (Most engine failures after takeoff occur during the first power reduction.)
Reduced insurance rates are available to owners of R/STOL equipped aircraft due to the excellent safety record compiled through the years.
Enhanced cruise speeds on most models are a result of gap seals and a generally more efficient wing.
Automatic elevator trim that avoids need for pilots attention when flaps are extended during critical landing regime
R/STOL LEADING EDGE
A slight downward droop of the leading edge results when a cuff is added to the Cessna wing. Cessna has incorporated the drooped leading edge on many of their models built since 1972. The drooped cuff recontours and smoothes air-flow over the wing, particularly at high angles of attack. The R/STOL leading edge post-pones wing stall and gentles stall action when it does occur.
AUTOMATIC TRIM
R/STOL's patented system interconnects the stabilizer with the flaps to relieve the pilot from frequent retrimming as flaps are lowered. This automatic trim operation eliminates one pilot activity during landing approach or when "cleaning up" after takeoff.
STALL FENCES
A chord-wise fence installed on the upper wing surface forward of the flap-aileron location restricts outboard movement of low speed air which develops at the wing root when a stall begins. By maintaining a smooth unstalled airflow over the ailerons, full and responsive aileron control remains available well into the stall.
DROOPED AILERONS
R/STOLS's patented system droops ailerons symmetrically whenever the flaps are extended. In their drooped position, the ailerons increase outboard wing lift by recambering airflow as flaps do for the inboard wing section. Yet, the ailerons offer full roll-control response. Aileron droop is the key to R/STOL's Hi-Lift System for single engine Cessna Aircraft.
DURING TAKEOFF
No (or less) offloading when flying from high altitude or high temperature airports with your Robertson-equipped Cessna. Hi-Lift extends sea-level, standard-day performance to high density altitudes - allows you to lift off heavy payloads from short runways or fly with full loads safely. Take off with enough fuel to avoid an extra fuel stop. R/STOL's extra performance adds flexibility to your flight operations - avoids extra trips - lets you fly into small airstrips closer to your final destination.
DURING APPROACH AND LANDING
R/STOL permits slow approaches with sharp, crisp control at slow speeds. You gain more decision time for correction and confident handling during crosswinds and gusts. R/STOL Hi-Lift Systems upgrade your Cessna permitting slower approach speeds that reduce wear and tear on landing gear, brakes, and tires. Even with power off you retain confident control with reduced risk of stalling. Overall, R/STOL's Hi-Lift System permits 15 to 25 MPH slower approaches and requires as much as 40% less runway distance.
