Controller Immediate Actions
-
1
7700 (EMERGENCY) on radarAttempt contact on last known frequency. If no reply, try 121.500. Advise supervisor immediately. Clear conflicting traffic. Prepare emergency runway / vectors.
-
2
7600 (RTF FAILURE)Transmit blind: "[callsign], if you read, squawk ident." Observe for ident response. Apply RTF failure procedures per ICAO Doc 4444 §15.5. Aircraft should proceed per ATC clearance then filed route at last assigned level.
-
3
7500 (UNLAWFUL ACT / HIJACK)Do not transmit suspicious information on RT. Notify supervisor using discreet means. Continue providing ATC service normally. Coordinate silently with adjacent units.
-
4
Declared minimum fuel"MINIMUM FUEL" — acknowledge, expedite sequencing, advise other traffic to expect delay. Not an emergency itself.
-
5
FUEL EMERGENCY / MAYDAYFUELTreat as full MAYDAY. Immediate sequence priority. Issue direct routing, clear runway. Notify ARFF (Fire service).
-
6
Medical emergency on boardIssue lowest workload routing. Request aircraft state: souls, fuel, aircraft type. Coordinate with adjacent ATC. Notify aerodrome services at destination.
-
7
Multiple simultaneous emergenciesPrioritise based on severity: MAYDAY > PAN > Minimum fuel. Segregate on separate frequencies if available. Call for supervisor immediately.
RTF Failure — Pilot Actions (ICAO)
When an aircraft experiences radio failure, the pilot will attempt to re-establish contact. Controllers should expect the following sequence:
Controller: Transmit blind on last freq
[Callsign], [ATC unit]. If you read, squawk IDENT.
[Callsign], if you read, turn right heading [XXX] and squawk IDENT.
[Callsign], if you read, turn right heading [XXX] and squawk IDENT.
Minimum Separation — Quick Reference
| Type | Environment | Minimum |
|---|---|---|
| Radar — horizontal | En-route | 5 NM |
| Radar — horizontal | Terminal (≤60 NM) | 3 NM |
| Vertical | Below FL290 (RVSM off) | 1000 FT |
| Vertical | FL290–FL410 (RVSM) | 1000 FT |
| Vertical | Above FL410 | 2000 FT |
| Wake Turbulence — HEAVY behind HEAVY | ILS approach | 4 NM |
| Wake Turbulence — MEDIUM behind HEAVY | ILS approach | 5 NM |
| Wake Turbulence — LIGHT behind HEAVY | ILS approach | 6 NM |
| Procedural — same track | No radar | 10 MIN |
| Oceanic standard | No radar | 50 NM / FL |
RVSM: FL290–FL410 available for appropriately equipped aircraft. Verify RVSM status before assigning levels within block.
Wake Turbulence Categories
| ICAO Cat. | MTOW | Example Aircraft |
|---|---|---|
| J — SUPER | >560,000 kg | A380 |
| H — HEAVY | >136,000 kg | B747, B777, A330, A340, B787, A350 |
| M — MEDIUM | 7,000–136,000 kg | A320, B737, A321, E175, CRJ |
| L — LIGHT | ≤7,000 kg | C172, PA28, King Air |
RECAT-EU applies at some European airports (replaces ICAO WT cats with A–F spectrum). Levant region airports use standard ICAO categories unless notified by NOTAM.
