SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
eNfusion™ HSD-128 High-speed Data Terminal
• As directed in previous tests, connect a computer to the maintenance port
and use Level 2,
maint password to access the HSD maintenance utility
program.
• Power up all avionics and align the IRS.
• Taxi or tow the aircraft to an unobstructed, line-of-site location where a
complete 360
° rotation is possible.
(b) Antenna Tracking Verification Procedure
1. From the “reports” menu, enable items 8, 20, and 23.
Note: Reports item 8 (starboard antenna status word) is ONLY required where
conformal antennae are installed.
2. Position the aircraft at a baseline, start-of-test heading (0° recommended).
3. Confirm that the baseline heading, as reported by the aircraft IRS is similar
to that reported from the “HD” entry in reports item 23.
4. Record the following data in "Installation Checklist" on page D-1:
• Antenna selected—port or starboard (conformal only)
• Antenna gain and azimuth angle
• Heading
• Channel Card number “1” and “2” C/No and signal level
5. Rotate the aircraft through a full 360° circle while stopping to record data at
the following heading intervals:
• For conformal or phased arrays—every 15°
• For mechanically steered antenna—every 30°
(9) Optional System Checks
The following procedures are recommended—but not essential; however, they serve
to confirm successful completion of all previous tests.
(a) Preparation
Activate report items 21 and 23 for the following checks.
(b) Optional Voice/Data Calls Procedure
Note: As in previous tests, open a log file to capture all maintenance port activity
during aircraft taxiing, flight, and landing segments.
1. Voice/data calls – ground segment:
• Place any combination of voice and/or data calls while the aircraft is taxied
in a full circle and/or and figure 8 pattern. Note any voice or data anomalies.
2. Voice/data calls – in flight:
• Place any combination of voice and/or data calls during any of the
segments listed above. The flight pattern may include “standard rate of
turn”, figure 8s, or circles. Note any voice or data anomalies.
