is enough for the required accuracy.
"We are a little concerned because at
this point, there's no ground-based ADS-B
[planned for Canada]. My transponder
antenna points at the ground. I'm thinking
the industry should be looking at something
different," he said. "If I got a top-mounted
antenna on my aircraft, would I still be picked
up by antennas on the ground?" Gervais
thinks that for VFR aircraft not requiring IFR
separation, a belly-mounted antenna could be
enough. "There is still a lot to determine."
When Nav Canada expands ADS-B into
Phase 3, which could include terminal airspace, he expects the agency to conduct a
formal aeronautical study-normal any time
a service is changed-and that COPA would
be part of its stakeholder group.
In late 2017, with only the first 15 ADS-B
payloads in orbit, Aireon was busy evaluating preliminary satellite ADS-B data (see
"ADS-B: Taking the High View," January 2018
AOPA Pilot). The company saw a lot more aircraft than it expected. While noting that the
system was designed to receive signals from

top-mounted transponder antennas, Aireon
said that it can receive bottom-antenna-only
1090ES signals, depending on the angles and
position of the satellite.
For now, aircraft owners based in
Canada-or American owners who have not
equipped, and who want to ensure compliance with Canadian requirements-might
want to hold off until the requirements are
finalized. Unfortunately, the rapid approach
of the FAA mandate might make this difficult. And owners interested in the FAA's
$500 ADS-B rebate (www.faa.gov/go/rebate)
should not wait; in mid-February only 4,400
reservations remained. AOPA is not aware
of any other national air service providers in
the Aireon partnership that have announced
ADS-B mandates requiring antenna diversity.
THE REST OF THE WORLD

In Mexico, 1090ES ADS-B Out will be
required beginning January 1, 2020, in
Class A, B, and C airspace, and Class E
above 10,000 feet msl. It is required now
in Class E airspace over the Gulf of Mexico,

at and above 3,000 feet msl within 12 nm of
the Mexican coast.
The European Union will require
1090ES ADS-B Out by June 7, 2020, for
IFR aircraft with a maximum takeoff weight
heavier than 12,566 pounds (5,700 kg) or a
maximum cruise airspeed faster than 250
KTAS. ADS-B coverage will be spotty in
areas, and not fully integrated with air traffic management, in June 2020, but coverage
will be nearly complete-and completely
integrated-by December 2023. However,
there currently is no clear and harmonized
pan-European direction for GA surveillance
equipage, which risks continued and even
increasing GA equipment diversification
across the European countries.
Australia , China, Colombia, Hong
Kong, India, Indonesia, New Zealand,
Singapore, Sri Lanka, Vietnam, and
Taiwan-among other countries-also
require 1090 ES.
