Abstract:

Two RNAV vertical computers were evaluated to determine whether the RNAV computer errors exceeded the 100 foot vertical and 3000 foot horizontal error 2 sigma allowance suggested by the RTCA SC-116E study group. The evaluation procedure attempted to isolate the vertical from the horizontal errors, but could not do so. Therefore, the horizontal along-track error contributed to the vertical error effect. The vertical resultant error of the Ascent-Descent Director ADD and the Vertical Path Computer VPC were both within the error envelope allowed the 3D-RNAV computer. Author
