Why Passengers Open Windows Before Takeoff and Landing
Passengers are often instructed by flight attendants to open the airplane window shades before takeoff and landing, and while this might seem like a simple or even trivial request, it actually serves several important safety and operational purposes. Understanding why this procedure is necessary can help passengers appreciate the role it plays in ensuring a safe flight.
First and foremost, opening the window shades before takeoff and landing improves visibility for both passengers and crew members. In the event of an emergency, such as a sudden evacuation, having the window shades open allows passengers and crew to quickly assess outside conditions. This can include checking for fire, debris, or other hazards that might affect evacuation routes. If the windows were covered, it would be much harder to determine whether it is safe to open doors or slides on a particular side of the aircraft.

Additionally, during takeoff and landing, which are the most critical phases of a flight, the cabin lighting is typically adjusted to be dimmer. This is done to allow passengers’ eyes to adapt to outside light conditions, which is essential if a sudden evacuation becomes necessary. Open window shades help facilitate this adjustment by letting natural light into the cabin. If the shades remained closed, passengers’ eyes would be adapted to the dim cabin lighting, making it harder to see outside once the doors are opened.
Furthermore, keeping window shades open aids the flight crew in maintaining situational awareness. By observing the outside environment, pilots and cabin crew can detect potential issues on the runway or taxiway, such as obstacles, wildlife, or other aircraft. It also helps airport emergency responders see inside the cabin in case of an incident, enabling them to assess the situation and provide timely assistance.
In summary, passengers are required to open the airplane window shades before takeoff and landing primarily for safety reasons. It ensures clear visibility both inside and outside the aircraft, facilitates rapid evacuation if necessary, helps passengers’ eyes adjust to external lighting conditions, and assists crew and emergency personnel in monitoring and responding to any potential hazards. Though it may seem like a small detail, this simple action plays a crucial role in maintaining aviation safety.
