Abstract: Provided are systems and methods for controlling a search and rescue (SAR) light on a rotorcraft. The system includes a processor programmed to: for each cartesian input point in a sequence defining a cartesian pattern, determine an initial light head orientation as a function of the real-time rotorcraft state; generate and transmit a pan command and a tilt command as a function of the initial light head orientation and the cartesian input point; and identify a delta-range. A pan-tilt-zoom (PTZ) camera is configured to continuously slave and have a field of view centered on a beam axis of the SAR light. The PTZ camera captures a video stream and transmits it; zooms in on the field of view of the PTZ camera when the delta-range is positive; and zooms out on the field of view of the PTZ camera when the delta-range is negative.
