Interpretation

Aircraft operating in the Beirut FIR should be alert for possible GPS/GNSS signal loss due to increased jamming and/or spoofing. Conventional ATS routes, STARs, and approach procedures referenced to ground-based navigation aids are strongly recommended; RNAV (GNSS) STARs and RNP approaches may still be used at the pilot's request and discretion.
