Although Annex 17 is the primary reference for Security, operational defense and response procedures are scattered in other documents to ensure comprehensive coverage.

## ICAO Annex 2 (Rules of the Air)
*   **Unlawful Interference:**
    *   The pilot-in-command shall attempt to notify the appropriate ATS unit of this fact, any significant circumstances associated therewith and any deviation from the current flight plan necessitated by the circumstances.
    *   If unable to communicate, shall use the transponder code **7500** (Mode A).
*   **Interception:**
    *   Establishes standard signals and maneuvers for intercepted aircraft (e.g., follow instructions, rock wings, lower gear).
    *   Non-compliance with interception instructions may be treated as a security threat.

## ICAO Annex 6 (Operation of Aircraft)
Focuses on flight deck protection:
*   **Reinforced Cockpit Door:** Required on passenger aircraft of over **45,500 kg** or with a passenger seating capacity greater than **60**.
    *   must be resistant to penetration by small arms fire and grenade shrapnel.
    *   must be capable of being locked and unlocked from either pilot’s station.
*   **Monitoring:** Means shall be provided (e.g., peephole, CCTV) for monitoring the area outside the door to identify persons requesting entry.
*   **Checklists:** The operator shall establish checklist procedures for searching the aircraft for concealed weapons, explosives or other dangerous devices (e.g., pre-flight).

## ICAO Annex 14 (Aerodromes)
*   **Fencing:** Fences or other suitable barriers shall be provided to prevent the entrance to the movement area (airside) and other facilities.
*   **Isolated Aircraft Parking Position:**
    *   An isolated aircraft parking position shall be designated for the parking of aircraft known or believed to be the subject of unlawful interference.
    *   Location: At least **100 meters** from other parking positions, buildings or public areas.

## ICAO Doc 4444 (PANS-ATM)
*   **ATC Procedures:**
    *   The controller shall attend to the requests of the aircraft (levels, routes) without compromising the safety of others.
    *   Minimize instructions that might jeopardize the crew (assume hijackers are listening/monitoring).
    *   Notify immediately the appropriate authority and other ATS units.
    *   Covert confirmation of code 7500 if no clear verbal communication is possible.
