1. An aircraft comprising:

  • a fuselage (230);

    wings (232, 234) coupled to the fuselage;

    a plurality of planar phased array antennas (106, 132, 134, 210-218, 260) coupled to a transceiver (104) and fixedly attached to the fuselage or at least one of the wings, the plurality of planar phased array antennas including a first planar phased array antenna (132, 210-218) having a first normal vector (220-228, 262, 264) and a second planar phased array antenna (134, 210-218) having a second normal vector (220-228, 262, 264), wherein the first normal vector is not parallel to the second normal vector, wherein the first planar phased array antenna (132) is configured to receive (702) a first signal corresponding to a communication link (336), and wherein the second planar phased array antenna (134) is configured to transmit (704) a second signal corresponding to the communication link; and

    the transceiver, the transceiver configured to couple to a feeder link antenna (110), the feeder link antenna configured to receive (952) flight path data associated with a flight path via a communication uplink, wherein a flight controller (112) is configured to operate the aircraft based on the flight path data.
