Database for world aircraft's common GICB capabilities
The common usage Ground-initiated Comm-B (GICB) capabilities refer to a set of Mode S transponder downlink capabilities that are often interested by air traffic controllers. They include, for example, ADS-B messages, Mode S enhanced surveillance replies, and Mode S meteorological reports.
This repository contains a dataset generated from the global Mode S data obtained by OpenSky receiver network. It is published to support the scientific paper for OpenSky 2020 Symposium: Mode S Transponder Comm-B Capabilities in Current Operational Aircraft. The process of data gathering and decoding is documented in this paper.
Dateset structure
The dataset data/gicb_db.csv includes approximately 50,000 aircraft over the world. The structure of this dataset is illustrated with the following data fragment (with commas removed):

The first three columns are transponder address, aircraft registration, and aircraft typecode. The remaining columns are Comm-B Data Selector (BDS) codes, which correspond to specific GICB capabilities. When a value is set to 1, the corresponding aircraft is capable of transmitting this type of downlink messages.
Common BDS codes
The relationships between BDS code and specific Mode S downlink messages are shown in the following table:
