Abstract: Aircraft flight management devices, systems, computer readable media, and related methods are provided. The present subject matter includes devices, systems, computer readable media, and related methods of providing flight management control during abnormal events and/or situations requiring diversion from the present mission. In some aspects, a system for providing flight management may include a computing platform with a processor, a memory, and a flight management application module (FMAM) configured to receive data from multiple servers. The FMAM may also calculate one or more aircraft ranges and/or diversion routes based upon the received data. In some aspects, systems and devices disclosed herein may be configured to provide diversion assistance by selectively displaying information including the map, one or more of the aircraft ranges, a vertical display, and information regarding one or more airports.
