What is a ICAO 24 bit address?
ICAO 24-bit address There are 16,777,214 (224-2) unique ICAO 24-bit addresses (hex codes) available. The ICAO 24-bit address can be represented in three digital formats: hexadecimal, octal, and binary. These addresses are used to provide a unique identity normally allocated to an individual aircraft or registration.
What is a hex code in aviation?
The hex code is a unique ICAO 24-bit address (part of the aircraft’s Certificate of Registration) used to identify the aircraft and broadcast by its Mode-S transponder. Normally, the hex code is never changed, but the onboard transponders can be re-programmed.
What is Mode S address?
Definition. Mode S is a Secondary Surveillance Radar process that allows selective interrogation of aircraft according to the unique 24-bit address assigned to each aircraft. Recent developments have enhanced the value of Mode S by introducing Mode S EHS (Enhanced Surveillance).
What is mode Charlie in aviation?
Mode A equipment transmits an identifying code only. Mode C equipment enables the ATCO to see the aircraft altitude or flight level automatically. Mode S equipment has altitude capability and also permits data exchange.
Where can I find ICAO 24 bit aircraft address?

How are 24bit aircraft identifiers assigned to aircraft?
One of the SSR Mode S concepts is to selectively identify and interrogate aircraft by use of unique aircraft addresses. Blocks of 24bit SSR Mode S addresses are allocated by ICAO to States of Registry and individual addresses are to be assigned to each suitably equipped aircraft by the State of Registry.
