The seemingly simple question of whether or not to leave an airplane window shade open during flight has sparked countless debates, fueled by passenger curiosity and varying interpretations of safety regulations. The French phrase "Faut-il laisser le hublot ouvert?" directly translates to "Should we leave the porthole open?", and this article will explore the nuanced answer, delving into the reasons behind airline procedures regarding window shades, particularly during takeoff and landing. While the simple answer might seem straightforward, the underlying rationale is multifaceted and involves safety, passenger comfort, and even the aircraft's structural integrity.

The primary reason airlines often request – and sometimes enforce – open window shades during critical flight phases like takeoff and landing is related to emergency procedures. In the event of an evacuation, open shades allow cabin crew and passengers to quickly assess the situation outside. Visibility is paramount; a darkened cabin with closed shades obstructs the view of potential hazards on the ground, hindering a rapid and efficient evacuation. This is particularly crucial in low-light conditions, at night, or in inclement weather. The time saved by having clear visibility can be the difference between a successful, timely evacuation and a chaotic, delayed one. The ability to quickly assess the position of emergency exits, potential obstacles, and the overall ground conditions is vital for effective emergency response.
Furthermore, open shades enhance the ability of emergency responders on the ground to quickly and accurately assess the situation. They can see into the cabin, observe passenger movement, and identify any immediate needs or injuries. This improved visibility facilitates faster and more effective coordination between ground crews and the flight crew, leading to a more streamlined rescue operation. The value of this enhanced visibility cannot be overstated, particularly in scenarios where seconds matter.
Pourquoi Faut-il (Why Should We)? The Role of Emergency Lighting and Passenger Comfort
While the primary focus is on emergency evacuation, the requirement for open shades also contributes to passenger comfort and safety in other ways. Natural light entering the cabin can help reduce anxiety during critical phases of flight. Many passengers experience heightened anxiety during takeoff and landing, and the presence of natural light can have a calming effect, reducing stress and promoting a sense of normalcy.
Beyond the psychological aspect, open shades can improve the effectiveness of emergency lighting. In the event of a power failure, emergency lighting systems are activated. Open shades allow this light to spread more effectively throughout the cabin, enhancing visibility and guiding passengers towards the exits. Closed shades can significantly reduce the effectiveness of emergency lighting, potentially creating confusion and hindering evacuation efforts.
Pourquoi Faut-il (Why Should We)? The Myth of Structural Integrity
While some suggest that open shades might affect the structural integrity of the aircraft, this is largely a misconception. Modern aircraft are designed to withstand significant pressures and stresses, and the impact of open or closed window shades is negligible in comparison. The structural integrity of the aircraft is not compromised by the position of the window shades. The pressure differential between the cabin and the outside environment is managed by sophisticated systems within the aircraft itself, irrespective of the shade's position.
