The Huntington Lift Reserve Indicator offers takeoff and approach airspeed information.
Most pilots are very familiar with both angle of attack and airspeed indicators.
In some situations, this data isn't enough. One instrument combines this data and presents it clearly to the pilot. The new instrument sensor is mounted with its probes at least four to five inches below the wing skin, where stable stream lines can be found. A recent NASA report concludes that these LRI streamlines bear a constant relationship to the pitch line of flight, throughout an 18 degree change in angle of attack. When Aviation Consumer , a publication not noted for its enthusiasm for many aviation products, borrowed one of Huntington's units for a brief flight test program, it decided to keep it in the company Mooney.
