Method and apparatus for calculating altitude based on barometric and GPS measurements A navigation device and a method of calibrating the same are provided. The device includes a barometric pressure sensor and a GPS receiver. A processor calculates barometric and GPS derived altitudes and, based on...
Method of calculating take-off weight of aircraft with hovering, comprises steps of measuring required hovering power at first and second moment in time, obtaining third values of second value associated with pressure at flight altitude, obtaining fourth values of third value associated with ...
A microprocessor (19) receives the pressure and fuel data and calculates fuel use versus time as a function of engine performance data, and oxygen usage versus time as a function of altitude, and ETP versus time as a function of altitude. The calculated values are input to an automatic ...
Additionally, the distance between each altitude line decreases as the height increases, which also signifies a second degree relation between the thrust and the altitude. Finally, the cross terms (those that contain both x and y variables), are used as they are necessary for an accurate fit ...
