What is required before entering Istanbul or Ankara FIR?

• A. ICAO flight plan
• B. ATC clearance
• C. VFR flight plan
• D. NOTAM

Answer: (A)

Entering a Turkish FIR requires filing an ICAO flight plan. This plan provides ATC with all the essential details of the flight—aircraft identification, whether you’ll be IFR or VFR, route, cruising altitude, speed, and estimated times—so controllers can manage traffic, ensure proper separation, and coordinate handoffs across airspace boundaries. Only after the flight plan is available can ATC issue the necessary clearance to enter the FIR, so the plan itself is the prerequisite, not the clearance. Notams inform about conditions but do not authorize entry, and a VFR flight plan is a type of ICAO flight plan, not the standalone prerequisite.
