An unmanned aerial vehicle configured to be operated relative to a land vehicle. The unmanned aerial vehicle includes a processing circuitry configured to operate the unmanned aerial vehicle in a self-propelled mode when the land vehicle is stationary or moving with a speed below a threshold speed or operate the unmanned aerial vehicle in a towed mode, in which the unmanned aerial vehicle is towed by the land vehicle, when the land vehicle is moving with a speed above the threshold speed.

A backup system (100) installed in an airplane comprises a controller (130), storages (140, 150), a detector (120), and an input apparatus (180). The first storage (140) stores a large amount of data needing to be backed up, such as software for on-board equipment and usage information for an entertainment apparatus (160) and a payment apparatus (170). Based on information from the detector (120) and the input apparatus (180), the controller (130) determines/predicts a transition to stable flight and determines a timing at which a backup operation will be carried out. In addition, an interruption of stable flight is predicted/determined and a backup process is interrupted. A priority is decided for each piece of data to be backed up, and a backup order is decided based on the priority. The backup system (100) predicts sections in which stable flight will be possible from meteorological information, etc., and performs backup.

A method and system for locating a high-intensity target light source (26) from an elevated observation location (Po), for instance in an aircraft. The target light source is located at/near an earth surface portion (30) and amongst reference light sources (16, 24, 25) arranged along the surface portion. This target light source emits light (28) with a peak radiant intensity that exceeds the intensity of the reference light sources by at least one order of magnitude. The method includes: acquiring, with an image recording device located at the observation location, images of the light and light emitted the reference light sources; comparing the images and a digital ground map (50) that includes representations of the surface portion and of structures (20, 22) associated with the reference light sources, and estimating a location (Pt) of the target light source relative to the reference light sources, based on the comparison.
