Where can ADS-B be used?
ADS-B is required in Class A, B and C airspace within U.S. domestic airspace and all land mass regions of the U.S. as defined in 14 CFR 1.1 and it includes the states (contiguous and non-contiguous), U.S. possessions, or territories.
What information does ADS-B send?
ADS-B Out works by broadcasting information about an aircraft’s GPS location, altitude, ground speed and other data to ground stations and other aircraft, once per second. Air traffic controllers and aircraft equipped with ADS-B In can immediately receive this information.
When does ADS-B stop working on a plane?
1) ADS-B will stop working when the transponder is switched off at the gate after arrival in Tokyo. Airliners use the 1090 MHz Extended Squitter variety of ADS-B which is the worldwide standard. 2) I don’t have hard numbers but I guess it is approximately 90 percent of the flights.
How are ADS-B and ADS-C used on transoceanic?
Airliners use the 1090 MHz Extended Squitter variety of ADS-B which is the worldwide standard. 2) I don’t have hard numbers but I guess it is approximately 90 percent of the flights. At most economical cruise flight levels, ADS-C is mandatory. 3) ADS-C is a common system. For aircraft not equipped, position reporting of HF is the alternative.
Can a CPDLC be used in place of voice?
While CPDLC enhances ATS communications for normal use, it is not adequate for non-routine and emergency communications and therefore not appropriate as a basis for MMEL relief of HF communication systems (ref. FAA Legal Interpretation dated 06 Dec 2011 regarding 14 CFR § 121.99 data/com in lieu of voice requirements).
What does ICAO Doc 9869 say about satvoice?
[ ICAO Doc 9869, Table B-3] The SATVOICE system shall be capable of detecting loss of service, equipment failures and/or logon failures and provide indication to the controller/radio operator or flight crew of system status. You can use SATVOICE to communicate, but the RCP is no better than your HF radio, and not every SATVOICE system qualifies.
