Systems, computer program products, and methods for displaying navigation performance based flight path deviation information during the final approach segment to a runway and during landing of non-precision flight modes are provided. Improved graphical depictions of navigation performance based flight path deviation information provide pilots and flight crew members with clear, concise displays of the dynamic relationship between ANP and RNP, mode and aspect of flight and related procedures, intersecting flight paths, and current actual flight path deviation from a predefined flight path during the final approach segment to a runway and during landing. For example, an enhanced IAN display may include NPS-type deviation scales to show RNP/ANP relationships and predetermined RNP markers to alert the pilots and flight crew members that the FMC has transitioned from an NPS display for RNAV (LNAV/VNAV) flight procedures to an enhanced IAN display for a non-precision (non-xLS) approach and/or landing.

Automatically reconfiguring an electronic landing display that includes a flight path vector (FPV) symbol and a rising runway symbol combined with a digital altitude value that merge at low aircraft altitudes is disclosed. During approach, when the aircraft descends below a predetermined minimum altitude, e.g., 200 feet, the FPV symbol is removed. When the aircraft is on the ground and during takeoff, the rising runway symbol is removed. Removing one or the other of the merging symbols prevents the symbols from overlapping. Thus, the potential for pilot error due to one of the merging symbols occluding the other is avoided.
