Similar callsign or also called callsign
confusion, used in-flight communication. A similar
callsign is the identity between the ATC (Air Traffic
Controller) and the pilots. Air-Ground Communication is
a special means of communication intended to
accommodate ATC and Pilots' interaction to conduct a
safe and efficient flight operation. The pilot is responsible
for flying an airplane. The ATC has responsible to give
information and standard separation of all flights under
ATC’s responsibility or jurisdiction area. The acceptable
level of safety will indicate the success of air-ground
communication. The purpose of this study: 1) to describe
the risk of similar call sign in aviation, especially in
Makassar Air Traffic Service Center, and 2) to provide
the procedure to minimize the risk of similar callsign or
callsign confusion. The method used is the quan-qual
research by utilizing Ground Criterion Theory (GTC).
The theory postulated that the speaker and the listener
(agents) reached a state of the same thought—it about
what was said and meant. The data of this study are taken
from Makassar Air Traffic Service Center in Indonesia.
