Classification: CPC G  B | IPC B  G

Claim 5:
6. A flight controller for an aircraft, the flight controller comprising circuitry configured to:
receive electric field intensities at a plurality of positions of the aircraft to estimate a direction of an electric field around the aircraft based on information on relationships between directions of electric fields around the aircraft and electric field intensity distributions on the aircraft;
calculate a target airframe attitude to control an airframe attitude of the aircraft so that the electric field intensity distribution on the aircraft becomes uniform relative to the direction of the electric field, in which the electric field intensity distribution comprises one or more non-zero values; and
control the airframe attitude of the aircraft to cause the airframe attitude to be the calculated target airframe attitude, and select a flight route that aligns with the target airframe attitude to be calculated by the attitude calculator to minimize a risk of lightning strikes on the aircraft.
