INSIGHT ON ADS-B OUT
Like its fixed-wing counterparts, ADS-B Out is a major topic
among helicopter operators and avionics shops.
"They (helicopters) are required to have ADS-B Out installed,
but right now we're recommending to our customers that they not
rely on that technology (ADS-B) for their weather and traffic information," explained Steve Wysong, president of Wysong Enterprises. "I feel like the ADS-B In function is not going to be able to consistently receive the weather and traffic signals at the low altitudes
that these helicopters typically operate, especially EMS. They are
down low and operating in rural areas a lot. I just don't believe they
will receive the ADS-B In signal with any consistency."
Wysong said that with many of the upgrades his company has
done, they've had success in adding active traffic and XM Weather
systems in combination with ADS-B Out installations and expects
to see that continue for quite a while.
"The FAA is pushing the (free weather and traffic) capabilities
of ADS-B In as a way of selling operators on ADS-B Out, which is
the only requirement right now," he said. "But in a recent meeting
with the FAA, I asked about how it works for helicopters. They
agreed that sticking with active systems is probably the best way
to go right now.
"We deal mostly with single-engine, turbine helicopters, which
don't have the panel space or room for an external radome for onboard weather radar. That's where XM is nice."
Speaking of available panel space, helicopters typically don't
have much to spare, so selecting and positioning displays is critical
to a successful installation.
SMALL PANELS. BIG OPPORTUNITIES.
"Regarding the H-TAWS and radar altimeter mandates in particular, the FAA is requiring that they (H-TAWS visual warnings
and radar altimeter indicators) need to be installed right in front
of the pilot's primary field of view," Wysong said. "That's very
challenging with regular, independent displays. But with the new
multifunction displays, we can do a lot in a small space."
"With the advancements in panel-mounted avionics packages,
we have seen that this is often the perfect solution for helicopters
due to the limited space," stated Chris Jelinek, avionics operations
manager at Banyan Air Service. "And with the various manufacturers having dedicated H models specifically for helicopter installations, it's easier to match the equipment to the panel to the mission."
"With the new multifunction, flat screens, you can do a lot more
