A method including obtaining real-time data, wherein the real-time data is at least one of data associated with aircrafts in and around an airport, real-time weather information, and runway unavailability at the airport. The real-time data is analyzed. A holding time associated with an aircraft that is approaching the airport for landing is measured based on the analysis of the real-time data. A revised speed advisory is determined for the aircraft based on the holding time. The revised speed advisory is sent to a flight navigation and performance computer and/or a flight management system on-board the aircraft, wherein a speed of the aircraft is controlled based on the revised speed advisory.
