Claim Text:
1. A method, implemented in a computer system, of assisting with landing of an aircraft, the method comprising: determining, based on one or more current runway conditions during an approach of an aircraft to landing on a runway, a latest touchdown point on the runway, the latest touchdown point being calculated to permit stopping of the aircraft before reaching an end of the runway; determining a boundary descent path derived from a maximum allowable descent rate of the aircraft, the boundary descent path terminating at the latest touchdown point, such that the boundary descent path is configured to permit safe approach and touchdown of the aircraft on the runway at or before the latest touchdown point; and in response to the aircraft crossing within a selected margin of the boundary descent path, alerting an operator of the aircraft; wherein the latest touchdown point is calculated to be the latest touchdown point on the runway which will permit safe landing and stopping of the aircraft using maximum deceleration capability.
