If you are off your enroute course, GPS measures it as cross-track error: ±2.5 miles for non-WAAS full-scale devia-tion and ±1 mile if WAAS-equipped. Most of us are more familiar with angular course guidance, because this is how VORs and localizers operate. Angular guidance measures devia-

How to calculate Cross-Track error (GPS/Core Location)

http://www.jenxs.co.uk/Navfiles/trkcorr.html WebGPS RNAV systems can compute “track angle error” (TAE), the difference between the desired track and the actual track (Fig. 3). TAE is mathematically proportional to the rate of change of XTE, the important manual control variable. In principle, if TAE is available, the pilot would not have to chili\u0027s barrhaven
