5.7 VLOS Aircraft Operation. The remote PIC and person manipulating the controls must
be able to see the small UA at all times during flight. Therefore, the small UA must be
operated closely enough to the CS to ensure visibility requirements are met during
small UA operations. This requirement also applies to the VO, if used during the aircraft
operation. However, the person maintaining VLOS may have brief moments in which he
or she is not looking directly at or cannot see the small UA, but still retains the capability
to see the UA or quickly maneuver it back to VLOS. These moments can be for the safety
of the operation (e.g., looking at the controller to see battery life remaining) or for
operational necessity. For operational necessity, the remote PIC or person manipulating
the controls may intentionally maneuver the UA so that he or she loses sight of it for brief
periods of time. Should the remote PIC or person manipulating the controls lose VLOS of
the small UA, he or she must regain VLOS as soon as practicable. For example, a remote
PIC stationed on the ground utilizing a small UA to inspect a rooftop may lose sight of
the aircraft for brief periods while inspecting the farthest point of the roof. As another
example, a remote PIC conducting a search operation around a fire scene with a
small UA may briefly lose sight of the aircraft while it is temporarily behind a dense
column of smoke. However, it must be emphasized that even though the remote PIC may
briefly lose sight of the small UA, he or she always has the see-and-avoid responsibilities
set out in part 107, §§ 107.31 and 107.37. The circumstances of what would prevent a
remote PIC from fulfilling those responsibilities will vary, depending on factors such as
the type of UAS, the operational environment, and distance between the remote PIC and
the UA. For this reason, there is no specific time interval that interruption of VLOS is
permissible, as it would have the effect of potentially allowing a hazardous interruption
or prohibiting a reasonable one. If VLOS cannot be regained, the remote PIC or person
manipulating the controls should follow pre-determined procedures for a loss of VLOS.
These procedures are determined by the capabilities of the sUAS and may include
immediately landing the UA, entering hover mode, or returning to home sequence. Thus,
the VLOS requirement would not prohibit actions such as scanning the airspace or briefly
looking down at the small UA CS. |
