U.S. ADS-B Won't Work In Canada

RUSS NILES

Most U.S. general aviation operators will not be able to fly in Canadian controlled airspace and vice versa when Canada mandates ADS-B according to Nav Canada. The not-for-profit corporation is also majority owner of Aireon, a recently activated space-based ADS-B tracking system that requires ADS-B 1090ES transmitters with antennae on the top of the aircraft to properly track them. The U.S. uses a ground-based system that requires belly-mounted antennae. Aireon has tested belly-mounted antenna with its system and they don’t work. Nav Canada is telling Canadian pilots that its system will be exclusively based on the satellite system and they should be making their equipage decisions accordingly. In most cases, it’s not as simple as adding a second antenna to be able to fly in controlled airspace in both countries. Only a few GA systems offer the so-called “antenna diversity” ability. Nav Canada doesn’t make the rules in Canada. Transport Canada will have to issue the regulations requiring ADS-B compliance and so far hasn’t indicated those rules are imminent. But in a letter to a Canadian pilot who inquired about his ADS-B options, the Nav Canada spokesman who responded told him the Canadian mandate could be in effect as soon as 2023. He also said implementation for airspace outside the busiest major airports in Canada will involve more stakeholder consultation. The Aireon system uses transponders on a constellation of more than 60 low orbit Iridium satellites and can track any properly equipped aircraft anywhere in the world every second. The company intends to use the system to make air traffic management more efficient and accurate and is already using it in remote areas, like the North Atlantic, to reduce spacing between aircraft.
