Integrated approach navigation system, method, and computer program product

A computer program product for providing navigation performance based flight path deviation information for non-precision approach flight modes for an aircraft, the computer program product comprising a computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

• a first program code portion for providing at least one non-precision approach flight display during the non-precision approach flight modes for aircraft landing approach;
• a second program code portion for providing at least one of a lateral and a vertical flight path scale on the non-precision approach flight modes, wherein each flight path scale comprises a reference point bounded by end markers extending in at least one of a lateral and vertical direction, respectively, wherein the reference point relates to an actual flight path, and wherein the end markers represent a required navigation performance (RNP);
• a third program code portion for determining a deviation of the actual flight path of the aircraft relative to the predefined flight path and thereafter displaying at least one moveable deviation pointer on the at least one flight path scale based upon the deviation;
• and
• a fourth program code portion for determining an actual navigation performance (ANP) and the RNP based upon a flight phase of the aircraft and thereafter displaying a representation of at least one extendable navigation uncertainty bar on the at least one flight path scale based upon the ANP and RNP, wherein the representation extends from at least one of the end markers toward the reference point of the at least one flight path scale to thereby define at least one navigation performance suspect region.
