Event Reporting (Optional)
5. Monitoring the aircraft in the TracPlus Pro 3 (TPP3) mapping software and with the aircraft powered and
stationary:
a. Actuate the engine sensor for more than 2 seconds
to generate an “Engine On” event in TPP3.
b.
Release the engine sensor to generate an “Engine Off” event in TPP3.
c. Actuate the airborne sensor for more than 2 seconds
to generate a “Take-Off” event in TPP3 and for
more than 1
0 seconds to generate a “Hover Start” event (helicopters only). It is not possible to
generate a “Hover Stop” event on the ground however a successful hover start indication is sufficient
to verify functionality.
d.
Release the airborne sensor to generate a “Landing” event in TPP3.
e. Increase the volume reported by the volume sensor by a significant amount (to guarantee an event an
increase of >400 L (kg) is recommended) and hold
to generate a “Fill” event in TPP3.
i. For a Reabe probe system this can be achieved by accessing the aircraft hopper and lifting
the Reabe probe float to the top of the tank and holding it there.
f.
Actuate the container door sensor and, within 10 seconds, reduce the volume reported by the volume
sensor by a significant amount to generate “Drop Start” and “Drop Stop” events in TPP3.
NOTE
Once you have reached this point you have fully verified the proper installation and
configuration of the AFDAU-T1. The following functional checks are optional and are used
verify the end-to-end functionality of the event reporting system and may detect issues
unrelated to the installation.
NOTE
It is possible, but can be difficult, to simulate fill, drop start and drop stop events on the
ground. The following procedure is general and applicable to all types of volume sensors
however it is impractical for load cell type sensors without additional hardware. AMS does
NOT recommend suspending loads from the aircraft cargo hook for the purposes of
testing the AFDAU-T1 installation.
NOTE
Simply actuating the container door sensor does not generate a drop event. Drop events
are generated by the combination of a container door open signal and a detected
significant decrease in volume.
