I know. I'm talking about when they start flying again. Sunwing tends to use other airlines when they want to test out new markets or if load factors are low out of certain gateways. Last season they used Swoop.
Touché !
The B734 had issues with Alberta-South runs. Quebec-South runs pose no range issues for the B734. Their website says a range of 2,500nm, but the following maps are with an official Boeing range of 2,060nm with 147 pax, which I trust more.
They mean ADS-B. There are still a lot of 705 company airframes with no ADS-B in Canada.
How does it work in the middle of the Atlantic Ocean then?
Automatic dependent surveillance–broadcast (ADS–B) is a surveillance technology in which an aircraft determines its position via satellite navigation and periodically broadcasts it, enabling it to be tracked. The information can be received by air traffic control ground stations as a replacement for secondary surveillance radar, as no interrogation signal is needed from the ground. It can also be received by other aircraft to provide situational awareness and allow self-separation. ADS–B is "automatic" in that it requires no pilot or external input. It is "dependent" in that it depends on data from the aircraft's navigation system.[1]
Your information is not correct.BTD wrote: ↑Thu Jul 09, 2020 6:41 am I don’t believe it does. That is ADS C works in the middle of the ocean. Although your ADS B could be communicating with other ADS B capable aircraft nearby. ADS B needs satellite navigation (gps) for position, but then uses transponder and ground stations to pass that to ATC.

A significant step forward for ADS-B is the reception by artificial satellites of the ADS-B signal. It was tested for the first time in 2013 on ESA's PROBA-V[65] and it is being deployed by companies like Spire Global using low-cost nanosatellites. Aireon is also working on space-based ADS-B with the Iridium satellite network, a LEO (Low Earth Orbit) satellite network that was originally created to deliver phone and data service anywhere on the planet. By capturing ADS-B position data from aircraft flying below the satellite, the network will give the following capabilities:
Air traffic control using surveillance based separation standards will be possible over water, in areas that radar does not currently cover. Currently, air traffic control uses the larger procedural separation standard in oceanic and remote areas.
As is currently possible in radar covered areas, a position history will be available for lost aircraft, as in the case of Malaysia Airlines Flight 370.
The system only receives ADS-B on aircraft broadcasting on the 1090 MHz frequency. This limits the system generally to airliners and business aircraft, despite the fact that small aircraft are frequently off radar due to mountains blocking the signal at low altitudes. The system could be compromised by smaller, private aircraft with exclusively belly mounted ADS-B antennas, due to the aircraft hull blocking the signal.
The rationale for using the Iridium satellite network for this new capability was due to:
The Iridium satellites fly very low, and thus can receive the ADS-B out signals more reliably (transponders and ADS-B were designed for ground reception).
Iridium satellites are replaced relatively frequently due to the increased air friction at their lower altitude, and thus lower lifespan. Thus the system would be deployed on iridium faster.
Iridium provides worldwide coverage, including the poles.
In September 2016, Aireon and FlightAware announced a partnership[66] to provide this global space-based ADS-B data to airlines for flight tracking of their fleets and, in response to Malaysia Airlines Flight 370, for compliance with the ICAO Global Aeronautical Distress and Safety System (GADSS) requirement for airlines to track their fleets.[67] In December 2016, Flightradar24, entered an agreement with Gomspace for space-based tracking in 2016.[68]
SpaceX subsequently placed 66 operational and 9 spare Iridium satellites in orbit over the course of 8 launches between 14 January 2017 and 11 January 2019. Another 6 spare satellites remain on the ground.
The ICAO describes space-based ADS-B as a technology equalizer, offering developing nations an airspace surveillance capability. By 2020, 34 nations will deploy the system, including the 17 members of the Asecna in Africa, and the Cocesna air navigation services agency in Central America. More frequent updates in the North Atlantic Tracks allowed reducing longitudinal separation from 40 to 14 nmi (74 to 26 km) and lateral separations from 23 to 19 nmi (43 to 35 km). The FAA plans an evaluation in the Caribbean airspace from March 2020 until 2021, to complement the unreliable Grand Turk Island radar which allow reducing separation from 30 to 5 nmi (55.6 to 9.3 km).[69]
