ABSTRACT:
An instrument and method for continuously measuring by differential air pressure the surplus of kinetic energy of an aircraft mass and the resulting potential of wing lift (POWL) above an empirical datum which coincides with the incremental onset of mushing sink, and for coincidentally and continuously displaying the margin of measured airspeed above the calibrated datum within the airspeed range of transitional flight. The instrument includes a sensing probe having a pair of fixed plane surfaces normal to a common vertical plane and adjustably mounted in a region of induced, stable, incident airflow under the wing or other part of an aircraft to sense differential impact pressure on the fixed plane surfaces, and an instrument to measure and display the sensed differential pressure. The instrument datum is calibrated by adjusting the slope of the sensing probe to the onset of mushing sink at flared touchdown (POWL=0) so that the instrument can reproducibly display the margin of airspeed above POWL ZERO to enable a pilot to avoid mush/stall induced inadvertencies, and to knowledgeably control transitional flight.
