{{{#!td
Horizontal flight angle (in degrees) describing the flight direction. 
For example, if [#flight_angle flight_angle] = 0.0 (180.0), the aircraft moves parallel to the x-axis in positive (negative) x-direction, respectively. If [#flight_angle flight_angle] = 90.0 (270.0), the aircraft moves parallel to the y-axis in positive (negative) y-direction, respectively. Please note, the parameters has only an effect if the respective [#leg_mode leg_mode] is in 'cyclic'-mode, else the flight direction is determined directly by [#x_start x_start], [#x_end x_end], [#y_start y_start] and [#y_end y_end].

}}}
{{{#!td
Flight mode, either 'cyclic' or 'return'. In case of 'cyclic', the sensor keep moving further if the end-position (see [#x_end x_end] and [#y_end y_end]) is reached, i.e. the sensor moves cyclically through the model domain. Instead, in case of 'return', the sensor turns around at the end-position and flies back, where it turns around again at the start-position and so on, i.e. the sensor only moves between start- and end-position until [#flight_end flight_end] is reached.

Maximum possible elevation change in case [#rate_of_climb rate_of_climb] is not equal to zero. If the maximum elevation change is reached, the virtual aircraft start descending until the original start level is reached again. For longer flights, the sensor moves vertically between [#flight_level flight_level] and [#flight_level flight_level] + [#max_elev_change max_elev_change]. Please note, [#flight_level flight_level] + [#max_elev_change max_elev_change] must not exceed the top of the model domain.
