ADS-B EARLY ADOPTERS

data communication capabilities that tried-and-true technologies like
Mode C or S, and non-WAAS-enabled GPS, simply can't provide
without additional equipment or modiﬁcations. And it all must comply
with speciﬁed technical standard orders and be certiﬁed, as existing
IFR-qualiﬁed GPS navigator and transponder installations are today.
In a depressed market, the simplest, cheapest way to get ADS-B
Out aboard your aircraft may be to purchase one with it already
installed. That's especially true since few manufacturers today
publicly offer factory-installed ADS-B aboard new aircraft. While the
number of in-service aircraft equipped with ADS-B Out is relatively
small, it grows every day.
Regulatory hurdles don't seem to be a problem with installing
ADS-B aboard in-service aircraft. "The ones we have done are all
STC'd, so we haven't had any issues with FAA approvals," Fryar
said. Operators wanting to install equipment lacking an STC or
approved model list can ﬁnd themselves in "hurry up and wait" mode
while the FAA's bureaucracy works its magic, Anglisano added.
He also said most operators have adopted a "wait-and-see"
approach to ADS-B Out upgrades. "On the other hand, during major
upgrades, operators seem to want to get it over with and put the
stuff in now," he allowed. "Saying that, it's important to install a good
supporting hardware and software set - if that's possible - so future
upgrades are seamless."
At Sarasota Avionics, meanwhile, only a few customers seem
to be waiting. "I would say there are a few," Fryar said. "I truly
don't think the prices will go down if they wait, especially when you
compare it with the NEXRAD (next-generation radar) subscriptions
each year."
One reason operators looking to upgrade existing panels may be
waiting is, for some, there may be more questions than answers.
As too often is the case, the basic answer to the question of what it
will take to upgrade an existing panel to meet the 2020 ADS-B Out
requirement is, "It depends on what equipment already is installed in
the aircraft, along with its operating characteristics."
Painless upgrades?
One of the key requirements of the ADS-B Out standard
is accurate airborne position-ﬁnding. The vast majority of
contemporary ADS-B Out installations use WAAS-enabled GPS to
perform this task. It doesn't have to be WAAS GPS, but it's a readily
available and well-understood technology meeting the standard.
Happily, that same onboard accuracy can be deployed to navigate,
resulting in ILS-like arrival procedures to airports lacking precisionapproach capability, among other beneﬁts. In other words, anyone
