1. A system for calculating and displaying formation flight information in an aircraft, to include the predicted trajectory of a second aircraft, using an augmented reality display device, the system comprising:
one or more augmented reality display devices wearable by a pilot of an aircraft, each located with a different aircraft in the formation, each augmented reality display device comprising:
one or more gyroscopes for measuring orientation and/or angular velocity of the pilot and/or one or more compasses for determining direction of the pilot;
one or more transceivers for transmitting and receiving data with an operatively coupled computing device in the same aircraft; and
one or more augmented reality displays comprising a display screen at least partially transparent which is configured to display information; and
one or more computing devices, each located within a different aircraft in the formation, to include at least one aircraft in the formation containing an augmented reality display device, each computing device comprising and/or operatively connected to:
one or more pressure sensors for measuring ambient pressure outside each aircraft;
one or more global positioning system (GPS) receivers for determining and tracking the position of each aircraft;
one or more transceivers for transmitting and receiving data with a computing device in a second aircraft;
a processor configured to estimate aircraft relative position and altitude as a function of the outputs of one or more pressure sensors, one or more GPS receivers, and/or data received from the computing device in the second aircraft;
one or more transceivers for transmitting and receiving data with an operatively coupled augmented reality display device; and
a virtual overlay program for displaying information relating to aircraft relative position on the screen of the operatively coupled augmented reality display device.
