1. A method of assisting an aircraft for landing at an airport, the method comprising:

  • determining a flap extension point for an approach to the airport based at least in part on a decision point proximate the airport and one or more stabilization criteria, the one or more stabilization criteria including at least one of a maximum airspeed limit and a maximum descent rate limit;

    determining one or more validation criteria associated with the flap extension point based on the one or more stabilization criteria, wherein the one or more validation criteria include at least one of a minimum airspeed at the flap extension point and a maximum airspeed at the flap extension point;

    obtaining, from a system onboard the aircraft, a current position of the aircraft and a current velocity of the aircraft;

    determining a descent strategy for the aircraft from the current position to the flap extension point based at least in part on the current position, the current velocity, and the one or more validation criteria associated with the flap extension point, wherein the descent strategy comprises one or more actions to decrease an energy level of the aircraft to satisfy the one or more validation criteria upon reaching the flap extension point; and

    providing graphical indication of the one or more actions of the descent strategy on a display device at respective points along a route from the current position to the airport.
