Disclosed herein is a method and system for flying rotary wing drone. An add-on flight camera that is free to rotate around the vehicle's yaw axis is attached to the drone. The flight camera is automatically looking in the direction of its flight. The video from the flight camera is streamed to the operator's display. Thus the rotary wing drone can fly in any direction with respect to its structure, giving the operator a first person view along the flight path, thus keeping high level of situational awareness to the operator. The information required for controlling the camera orientation is derived from sensors, such as GPS, magnetometers, gyros and accelerometer. As a backup mode the information can be derived from propeller commands or tilt sensors.

1. A method for remotely piloting a rotary wing drone flying in any direction, by streaming to the drone's operator a first-person-view video in the direction of the drone's flight, regardless of the drone's yaw, the method comprising: a. fitting the drone with a video camera capable of rotating around the drone's yaw axis;b. acquiring the projection of the drone's flight direction on the natural plane in local coordinates;c. automatically turning the video camera so that the center of its field of view is aligned with the projection of the drone's flight direction on the natural plane; andd. continuously streaming the video from the video camera to an operator's client, where the projection of the drone's flight direction on the natural plane is computed from commands applied to the drone's rotors. 2. A method for piloting remotely a rotary wing drone in any direction relative to its local coordinates, by streaming first-person-view video to the drone's ground operator, where the center of field of view is pointing in the direction of the drone's flight, regardless of the drone's yaw, the method comprising: a. fitting the drone with a plurality of fixed video cameras that provide 360 degree video coverage around the drone's yaw axis;b. acquiring the projection of the drone's flight direction on the natural plane;c. using the fixed cameras' 360 degrees video, encode a limited field-of-view video, with the center of its field of view aligned with the projection of drone's flight direction on the natural plane; andd. continuously streaming the video from the encoded limited field-of-view video camera to an operator's client,where the projection of the drone's flight direction on the natural plane is computed from commands applied to the drone's rotors. 3. A method for remotely piloting a rotary wing drone equipped with a documenting video camera, flying in any direction, by streaming to the drone's operator a first-person-view video in the direction of the drone's flight, regardless of the drone's yaw, the method comprising: a. fitting the drone with a flight video camera capable of rotating around the drone's yaw axis;b. acquiring the projection of the drone's flight direction on the natural plane in local coordinates;c. automatically turning the flight video camera so that the center of its field of view is aligned with the projection of the drone's flight direction on the natural plane; andd. continuously streaming the video from the flight video camera to an operator's client, such that the documenting video camera may document a subject outside the flight video camera's field of view while the flight video camera is aligned with the projection of the drone's flight direction on the natural plane, where the projection of the drone's flight direction on the natural plane is computed from commands applied to the drone's rotors. 4. A method for piloting remotely a rotary wing drone equipped with a documentary camera in any direction relative to its local coordinates, by streaming first-person-view video to the drone's ground operator, where the center of field of view is pointing in the direction of the drone's flight, regardless of the drone's yaw, the method comprising: a. fitting the drone with a plurality of fixed flight video cameras that provide 360 degree video coverage around the drone's yaw axis;b. acquiring the projection of the drone's flight direction on the natural plane;c. using the fixed flight cameras' 360 degrees video, encoding a limited field-of-view video, with the center of its field of view aligned with the projection of the drone's flight direction on the natural plane, andd. continuously streaming the encoded limited field-of-view video to an operator's client,such that the documenting video camera may document a subject outside the flight video camera's field of view while the flight video camera encoded field of view is aligned with the projection of the drone's flight direction on the natural plane, where the projection of the drone's flight direction on the natural plane is computed from commands applied to the drone's rotors.
