Abstract
A method for correcting an ambient pressure measurement, a method for calculating a temperature, and an apparatus for affecting the same for an aircraft measuring system are provided. The methods include the steps of receiving an airspeed measurement from a laser sensor, receiving a total pressure measurement, and calculating an ambient pressure correction. A corrected ambient pressure or a calculated temperature may be calculated. The apparatus includes a laser sensor configured to provide an airspeed measurement, an aircraft instrument configured to provide a total pressure measurement, and a processing system.
