OBS
I
NDICATOR
When the Obstacle Avoidance System (OBS) is activated, the H520 uses the two
sonar sensors (sender and receiver units on the front of the H520) to detect and
avoid forward collisions with objects. OBS will limit the forward speed to 4 m/s
of the H520 to ensure the highest probability of avoiding a forward
collision. There are three states of the OBS using switch S3 on the top left of the
ST16S.
Using switch S3 on the ST16S, the Pilot can toggle the Obstacle Avoidance
System (OBS). When Switch S3 is in the top position the OBS is set to off. When
switch S3 is in the center position the OBS is in standby mode. When switch S3 is
in the full down position, OBS is active.

Note:
It is recommended to disable Obstacle sonar prior to launching or landing. Move the
OBS Avoid (Switch 3) to the
center
position to deactivate OBS Avoid.
