Engineering firm has produced aviation performance and safety equipment for more than 75 years.
As a young US pilot in training, future aerodynamics engineer Leonard Greene witnessed a fatal plane crash caused by an aerodynamic stall. Changed by the experience, he began designing a solution to avoid similar accidents. His work led to the invention of the aircraft stall warning device.
In 1937, Greene began lobbying the US Civil Aeronautics Administration, predecessor of the FAA, to require stall warning systems on all aircraft, providing a crucial element of safety that has since been credited with saving more lives than any other single aviation safety device, according to Safe Flight Instrument.
Greene founded Safe Flight in 1946 to manufacture his device. Based in White Plains, New York, the company has since developed several additional safety enhancements, including the angle of attack indicator, automatic throttle system, wind shear warning, and many other aircraft instrumentation, flight performance, and control systems for airplanes and helicopters.
Dedicated to Performance and Safety
Safe Flight has remained dedicated to the production of aviation performance and safety equipment for more than 75 years. Since starting out with a focus on aircraft lift instrumentation, the firm has expanded its product line from simple switch-type stall warning systems for light aircraft to sophisticated systems for today’s airlines, helicopters, and heavy aircraft. The company now designs, develops, and produces a variety of equipment aimed at improving performance and safety for a wide range of fixed-wing, helicopter, general aviation, corporate, commercial, and military aircraft.
Today, Safe Flight’s FAA-certified products are available on nearly every type of aircraft. Most aircraft manufacturers offer Safe Flight systems as standard or optional equipment. Safe Flight now counts the majority of the world’s aircraft manufacturers—more than 50 airlines, hundreds of corporate jet aircraft operators, and all the US Armed Forces—among its customers.
Safe Flight’s helicopter innovations include solutions to help operators detect power lines and avoid operating exceedances. The company’s power-line detection system senses when a helicopter is in proximity to a power line and uses audio and visual warning signals to alert the pilot.
The company used its 50 years of fixed-wing stall warning technology experience to develop tactile warning systems to enhance helicopter operations. The collective shaker system simultaneously monitors several engine and rotor system limits, such as torque, exhaust gas temperature, gas producer speed, and rotor speed, shaking the collective when an operating limitation is being approached to help pilots avoid dangerous situations, especially in high-workload environments. Similarly, the pedal shaker system warns of approaching pedal limits.
Safe Flight focuses on keeping pace with emerging technologies while working closely with customers to solve their problems. The firm continues to invest in research and development, planning the instrumentation concepts for tomorrow’s aircraft.
