1. A system to assist piloting an aircraft in landing phase comprising:
a pseudo glide path calculation module comprising:
one or more processors; and
a memory communicatively coupled to the one or more processors and having instructions stored upon, which when executed by the one or more processors, cause the one or more processors to:
receive coordinates for a runway;
receive exit path coordinates for the runway;
receive aircraft configuration data; wherein the aircraft configuration data comprises an aircraft weight;
receive aircraft status data; wherein the aircraft status data comprises aircraft velocity data;
receive runway environmental data; wherein the runway environmental data comprises an estimated wake turbulence of a preceding aircraft landing on the runway;
calculate a relative position of the aircraft in reference to the exit path coordinates and the runway environmental data;
generate a pseudo displaced threshold for the runway based on the exit path coordinates, the aircraft configuration data, the aircraft status, and the runway environmental data, wherein the pseudo displaced threshold is calculated so that the aircraft may turn onto the exit path coordinates and to ensure the aircraft is not affected by the estimated wake turbulence of the preceding aircraft; and
generate a pseudo approach glide path profile based on the pseudo displaced threshold; and
a display, wherein the display overlays the pseudo displaced threshold and the pseudo approach glide path profile onto the runway.
