Systems and methods for airport selection and display of range remaining during engine out conditions

A method for flight guidance for airport selection during engine out (EO) conditions in an aircraft, the method comprising:

• at a controller architecture programmed by programming instructions,
• processing received aircraft status data to determine, continuously, a current location and trajectory of the aircraft;
• processing received engine status to determine whether an EO condition is indicated;
• responsive to determining that an EO condition is indicated,
• generating a notification of the EO condition;
• determining when an enable is valid for EO guidance;
• receiving an activate EO guidance command;
• and
• beginning an EO guidance mode responsive to receiving the activate EO guidance command when the enable is valid;
• and
• while in the EO guidance mode, performing EO guidance operations including:
• computing an optimal EO destination airport and corresponding path to it from the current location;
• presenting the optimal EO destination airport and the corresponding path for a pilot to review;
• receiving a pilot selection of the optimal EO destination airport subsequent to presenting the optimal EO destination airport;
• constructing a lateral and a vertical glide path to the optimal EO destination airport;
• tuning a multi-mode digital radio (MMDR) to an appropriate frequency if the pilot selection includes an Instrument Landing System (ILS) approach;
• and
• creating a plurality of glide profiles for each of a plurality of radials extending from the current location, each glide profile having a range that indicates an aircraft specific performance in wind and loss of potential energy due to lateral maneuvers.
