Procedimiento y sistema de guiado de aviones

摘要

The present invention relates to a system and method for steering aircraft along a predetermined track. Particularly, but not exclusively, the invention relates to steering an aircraft along a lateral path (e.g. a track described by reference to latitude and longitude) by a method comprising: calculating a nominal track correction; providing an upper limit and a lower limit for the nominal track correction; setting a desired track correction as: (i) the nominal track correction if the nominal track is between the upper limit and the lower limit; (ii) the upper limit if the nominal track correction is greater than or equal to the upper limit; or (iii) the lower limit if the nominal track correction is less than or equal to the lower limit; and steering the aircraft using the desired track correction.
