Interpretation

Flights operating in the Kabul FIR must follow ICAO TIBA procedures. Overflights must broadcast intentions on 125.2 MHz at least 10 minutes before entering the FIR. Arrivals and departures must use 125.4 MHz for Kabul (OAKB), 135.35 MHz for Mazar-e-Sharif (OAMS), 125.5 MHz for Kandahar (OAKN), and 123.35 MHz for Herat (OAHR). Before takeoff, pilots must broadcast their intentions, including runway, departure track, and intended cruising level, on the relevant TIBA frequency at least 10 minutes in advance. During an emergency descent, ICAO Doc 4444 PANS-ATM Section 15.1.4.2 applies, except the pilot must broadcast on the relevant TIBA frequency instead of advising ATS.
