The lack of using TIBA in our country caused the biggest aviation disaster in our country, when a midair collision between a US starlifter and a German Tupolev occurred in 1997 killing 34 people on board. One of the aircraft failed to broadcast his position on TIBA over the oceanic airspace. Had the aircraft complied, the other one would have picked it up that both were same level, but reciprocal tracks. IATA is also using an In-flight Broadcast Procedure (IFBP) over many African States, which has increased safety to a large extend.
