During exercise period all VTD area that are overlapped by COBRA GOLD 2026 areas will be not active. Aircraft not associated with COBRA GOLD 2026 exercise wishing to fly through the areas should contact "Live Fly Cell" on phone number +668 4251 9741or "OSCAR Control" on phone number +662 534 4731 to get permission before filing the flight plan.

8  AIR TRAFFIC FLOW MANAGEMENT DURING COBRA GOLD 2026 PERIOD

In response to the capacity constraint caused by the Joint Military Air Exercise "COBRA GOLD 2026" the following ATFM measures will be implemented:

8.1  The Ground Delay Program (GDP) may be implemented during the traffic congestion period. ATFM procedure is published in AIP Thailand ENR 1.9

8.2  Temporary Flight Level orientation scheme

Flights operating on the following routes are requested to use the following flight level orientation scheme:

8.2.1 Northbound flight from VTBD, VTBS, BKK via A464 (Portion BKK CMA) Y26, or Y27 – Odd FL

and flight depart from VTPI, VTBL, VTBH, VTPP via W9.

8.2.2 Southbound flight to VTBD, VTBS, BKK via Y7, Y28 or W9 or other airways joining W9. – Even FL
