Mode A is a transponder function that transmits a 4-digit octal identification code for an aircraft's identity when interrogated by an SSR.
Mode A code is the 4-digit octal identification code transmitted by a Mode A transponder function.
Mode C is a transponder function that transmits a 4-digit octal identification code for an aircraft's pressure altitude when interrogated by an SSR.
Mode S is a transponder function that uses a unique aircraft address to selectively call individual aircraft, and supports advanced surveillance using Mode S EHS, Mode S ELS, or Mode S ES capabilities.
Mode S EHS means Mode S enhanced surveillance, which is a data transmission capability of a Mode S transponder.
Mode S ELS means Mode S elementary surveillance, which is a data transmission capability of a Mode S transponder.
Mode S ES means Mode S extended squitter, which is a data transmission capability of a Mode S transponder used to transmit ADS-B OUT information.
