The course correction implementation of the inertial navigation system based on the information from the aircraft satellite navigation system before take-off

The trend of development of modern on-board aircraft systems causes the emergence of new requirements, in particular, to maintain the specified accuracy characteristics while the air navigation. One of these requirements is the implementation of reverse flight schemes, which include standard turns and final turns with the control of the exit to the line of a given path with the return course. Taking into account the fact that the reverse schemes do not solve the problem of providing an exit to the line of a given path at a given control point. The method of using alternative reverse schemes is proposed to solve the problem of ensuring the end of the reversal in the reverse schemes at a given point. The given point of the exit on the path line with the return course is applied as a reference control point in these schemes. The presented method provides the construction of standard turns in relation to the point of return to the path line. The method is used in the preparation of schemes of turns and is used by the onboard aircraft navigation system when flying according to these schemes. The method allows to ensure the end of the turn with the exit to the line of a given path at a given point, as well as to reduce the area of the protected space of the turn zone.

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.
