China requires passengers to keep their windows closed during take-off and landing to protect national security.

China is requiring passengers to keep their windows closed during take-off and landing at airports used for both civilian and military purposes. This measure is designed to prevent the capture of sensitive images that could threaten national security. Although different from normal security practices, this instruction has been put in place to prevent leaks of military information.

The national security context in China

China’s decision to ask passengers to keep their windows closed during take-off and landing comes against a backdrop of heightened national security. China’s Ministry of State Security issued the warning via WeChat, stressing the need to limit the risk of sensitive information leaking out. This measure particularly concerns airports with mixed civil and military use, which account for around a third of China’s airports.

Mixed-use airports are infrastructures where civil and military operations are carried out jointly. Capturing images or videos of these areas can reveal strategic information about the country’s military capabilities. For example, images of military aircraft or troop movements can provide crucial data to foreign entities.

Advantages: This measure makes it possible to protect sensitive information and ensure national security by preventing potential leaks of military intelligence.

Disadvantages: It contravenes standard aviation safety practices which recommend keeping windows open for visibility and safety reasons during emergency evacuations.

Consequences: The measure could lead to complications in emergency situations where external visibility is crucial for passengers and rescuers.

Impact on air safety practices

Traditionally, air safety rules require passengers to keep their windows open during take-off and landing. This practice aims to maximise external visibility in the event of an emergency, thereby facilitating evacuation and making it easier for rescue workers to spot signs of smoke or fire.

According to Amsterdam’s Schiphol airport, this practice helps to ensure passenger safety in the event of a problem. By keeping the windows open, passengers and crew can better assess external conditions and react accordingly. However, the Chinese rule imposes an additional constraint that runs counter to this international standard.

Benefits: The Chinese measure strengthens national security by minimising the risk of espionage or leaks of military information.

Disadvantages: It may create confusion among passengers accustomed to international security standards and potentially compromise safety in the event of an emergency.

Consequences: This divergence from international practices could lead to misunderstandings and disagreements between the Chinese aviation authorities and foreign airlines operating in China.

Examples of national security incidents

The Chinese Ministry of State Security has cited recent incidents to justify this measure. For example, a foreign national was suspected of illegally capturing images from his aircraft window at a mixed-use airport. In another case, a flight had to return to the gate for security checks after a passenger repeatedly opened his window to take photos. This passenger was detained for seven days.

These incidents illustrate the risks associated with capturing images in sensitive areas. The detention of the passenger shows the severity with which China deals with these violations, underlining the importance attached to the protection of strategic information.

Benefits: Highlighting these incidents raises passenger awareness of the risks and justifies the increased security measures.

Disadvantages: Such strict measures may be perceived as excessive by passengers and international observers, which may affect China’s perception of individual freedoms.

Consequences: The implementation of such measures could deter some travellers from flying with airlines operating in China, potentially affecting the airline industry.

Analysis of the advantages and disadvantages

The instruction to keep windows closed has both advantages and disadvantages. On the one hand, it strengthens national security by preventing the capture of sensitive images. On the other hand, it goes against internationally recognised aviation safety practices.

Advantages :

• Increased protection of sensitive information.
• Reduced risk of espionage.
• Enhanced national security.

Disadvantages :

• Contradiction with air safety standards.
• Increased risk in the event of an emergency requiring rapid evacuation.
• Confusion and discontent among passengers.

Long-term consequences

In the long term, this measure could have several consequences. In terms of national security, it could effectively reduce the risk of espionage and information leaks. However, in terms of international relations and the aviation industry, it could create tensions and complicate the operations of foreign airlines in China.

Positive consequences :

• Better protection of military installations.
• Increased passenger awareness of national security issues.

Negative consequences :

• Potential reduction in the number of international passengers.
• Complications for foreign airlines.
• Possible criticism from the international community regarding individual freedoms.

China’s decision to require passengers to keep windows closed during take-off and landing at mixed-use airports reflects a priority given to national security. Although this measure contradicts traditional aviation security practices, it underlines the importance of protecting sensitive information. Passengers and airlines must adapt to these new rules while continuing to guarantee the safety of all on board.
