The invention discloses differing embodiments of methods, aircraft, and apparatus for communicating the braking conditions of a runway. In one embodiment, braking information may be determined from a first aircraft which has landed on the runway. The braking information may be communicated to air traffic control and/or a second aircraft. Communication of the braking information may take place utilizing an Automatic Dependent Surveillance Broadcast system (ADS-B) and/or other type of automatic networking system.
