Modern requirements in accuracy of aircraft flight trajectory following is done with specifications to the systems of zone navigation in the international air space RNAV (Area Navigation) and RNP (Required Navigation Performance) may apply tight restrictions for the possibilities to correct for the aircraft arrival time to the points of route. Applying the flight speed varying is often insufficient to be on the time chart because of restricted range of available speeds. Application of standard waiting zones in route and in the vicinity of the airport to eliminate the time excess is restricted to the value of minimal flight time which is around 4 minutes or more. As an alternative for arrival time excess elimination to the necessary route point you may use the method of parallel displaced trajectories which is supported functionally with RNP systems. This method is done in the on-board navigation system navigation in time. Depending on the value of the time arrival excess to the necessary route point the navigation coil in time creates the recommendations for the crew how to use displayed trajectories to form the necessary point of exiting to the displaced trajectory to define the side displacement and to evaluate the arrival time correction.
