(Image: ForeFlight) The latest version of the ForeFlight electronic flight bag app includes a new runway analysis feature, which is available to Performance-level subscribers as a paid add-on service. Runway analysis launched with six Cessna Citation models, but ForeFlight is adding more jets and eventually turboprops as well. Runway analysis allows pilots to fly with the maximum payload possible while meeting terrain- and obstacle-clearance requirements in case of loss of one engine during the takeoff phase of flight. Airlines have long used runway analysis engine-out procedures (EOPs) to allow dispatchers to calculate the highest possible maximum takeoff weight for specific runways while meeting minimum climb, available runway length, and obstacle clearance and other requirements. Runway analysis has increasingly become part of normal operations in business aviation, with analysis companies providing EOPs for many airports globally. While EOPs generally include straight-out takeoff and climb procedures, some EOPs may be designed to match airport departure procedures or standard instrument departures (SIDs). Other EOPs may dictate a different departure path that must be used in case of an engine-out emergency.
