Update to enhance cargo handliong, comm, nav and identification
systems
October through December was a critical time for the C-130J
Hercules' Block 5.4 upgrade, as testers here determined the final
adjustments needed to bring this software improvement to the
operational fleet.
Currently, the C-130J has certain operational limitations, but
the upgrade was designed to correct these shortcomings by enhancing
the cargo-handling system, as well as advancing the communication,
navigation and identification systems, officials said.
The 418th Flight Test Squadron's recent testing included
formation flying, air drop events, traffic collision avoidance
system tests, computer-based approach testing and the most
comprehensive noise and vibration tests ever conducted on the
C-130, said Maj. Clifton Janney, 418th FLTS multiengine test
pilot.
"One of the key functions we've been evaluating (is) upgrades
for the back end of the aircraft," said Michael Berard, program
manager. "This software tells us how to load the cargo and how to
get rid of it.
"Right now, the C-130J has limited air drop capability
releases," he said. "There is a 28,000-pound limit on the release
of container delivery systems even though the max allowable weight
is 42,000 pounds." This weight limit is because of safety issues;
the buffer stop assembly system that secures the pallets can only
withstand so much pressure.
"However, with the low velocity air drop capability," Mr. Berard
said, "we're allowed to drop the maximum weight, and (we) actually
performed (a) drop of 40,440 pounds."
The low-velocity pallets are bigger than standard pallets and
are held in place by anchors rather than the buffer stops.
"Our two-and-a-half-month testing (identified) these
discrepancies, as well as other problems with the defensive systems
and air land operations," Mr. Berard said.
The software was returned to the manufacturer and is currently
undergoing modifications to correct these deficiencies, he said.
Software testing will continue in February.
"When finished in May, we expect the air-drop envelope to be
cleared up to the max drop weight," Mr. Berard said. "We also
expect to see a better navigation solution and improved
communications."
The upgrades are scheduled to be operational within the C-130J
by the fall.
