Aircraft and In-Flight Security
Protecting the aircraft on the ground
The aircraft is most vulnerable on the ground: during turnaround, cleaning, catering and maintenance, many people access it. Controls include access control to the apron and stand, aircraft search before departure, sealing of holds and doors, supervision of catering and cleaning, and protection of the flight deck.
An aircraft search is a systematic inspection of defined areas to confirm the absence of prohibited items. It must be documented. If security was broken, a search is required even if it is inconvenient.
In-flight security
The flight deck door is the last barrier and must remain locked and controlled. Cockpit access procedures must be strict; no one enters on request alone. Cabin crew are the primary in-flight security resource, supported by behavioural observation, crew communication protocols, and where used, air marshals or onboard security officers.
The aircraft commander has authority over the aircraft and persons on board, including powers of restraint in accordance with the Tokyo Convention and national law. Security instructions to crew and search procedures for the cabin must be understood.
Traps
- Assuming the aircraft is secure because it is airside. Airside is not the same as secure.
- Forgetting that the last person to leave a compartment may be the threat.
- Confusing the commander's authority with police authority. The commander has defined powers, not general policing powers.
Rule of thumb
For any turnaround question, ask: who had access, was it controlled, and was the aircraft searched and sealed afterwards? If any answer is no, security has been compromised.
