Why do they tell you to open windows on a plane?

Answer:

When you are on a plane, you may have noticed that flight attendants always instruct passengers to open their windows before takeoff and landing. This may seem like a simple routine, but there is a good reason behind it. Opening windows on a plane serves multiple purposes, including safety and comfort.

One primary reason for opening windows is to equalize the pressure inside the cabin with that outside. As a plane ascends or descends, the air pressure changes rapidly. The cabin is pressurized to ensure a comfortable environment for passengers, but maintaining a consistent pressure can be challenging. By opening the windows slightly, it allows air to flow in and out, helping to balance the pressure, reducing the strain on the cabin structure.

Furthermore, opening windows aids in ventilation. As you may know, plane cabins are enclosed spaces where hundreds of passengers spend hours at a time. Ventilation is vital to ensure sufficient and fresh airflow throughout the cabin. Opening the windows allows for better circulation and creates a more pleasant environment for everyone onboard.

It is also important to note that in case of an emergency, opening windows can provide an additional exit route. In the event that the main exit doors become inaccessible or malfunction, passengers can evacuate the plane through the windows. This is particularly relevant during water landings when the doors may be submerged or damaged.

While opening windows on a plane may seem like a trivial instruction, it serves important purposes. It helps maintain pressure, improves ventilation, and provides an alternative exit route in emergency situations. So, next time you are on a flight, remember to follow the crew’s instructions and open your window as instructed.

Frequently Asked Questions about opening windows on a plane:

1. Is it necessary to open the windows during the entire flight?

Opening the windows is only required during takeoff and landing. Once the plane has reached its cruising altitude, it is no longer necessary to keep the windows open.

2. Can’t the cabin pressure be regulated without opening the windows?

While the cabin pressure is regulated, opening the windows helps to equalize the pressure more efficiently and reduces the strain on the cabin structure.

3. Does opening the windows affect the temperature inside the cabin?

Opening the windows may have a slight impact on the cabin temperature, but it is generally minimal. The aircraft ventilation system ensures that the cabin remains comfortable regardless of the window position.

4. Are there any risks associated with opening the windows?

No, there are no significant risks associated with opening the windows as long as passengers follow the crew’s instructions. Opening windows can only be done during specific phases of the flight for safety reasons.

5. Why do some passengers prefer to keep their windows closed?

Some passengers prefer to keep their windows closed for various reasons, including personal preference, reducing glare on screens, or minimizing exposure to sunlight.

6. Are there any restrictions on how much the windows can be opened?

Yes, there are specific guidelines provided by the airline regarding the maximum allowable window opening. These guidelines ensure safety and prevent any potential hazards.

7. Can passengers open the windows on their own or do they require assistance?

Passengers can open the windows themselves. However, flight attendants may assist passengers who might have difficulty with the window mechanisms.

8. Do all planes have windows that can be opened?

Not all planes have windows that can be opened. Modern commercial aircraft typically have windows that cannot be opened, providing a more robust structure.

9. Are there any situations where the windows should not be opened?

There are specific situations, such as extreme weather conditions or emergency evacuations, where it is advised not to open the windows. In such cases, passengers should follow the instructions provided by the flight crew.

10. What happens if a passenger violates the rule and keeps the window closed?

If a passenger intentionally disregards the instruction to open the window, it may result in a warning and could be seen as a violation of the airline’s safety regulations.

11. Can keeping the windows closed cause discomfort to other passengers?

While it is generally recommended to follow the crew’s instructions and open the windows, keeping them closed is unlikely to cause significant discomfort to other passengers.

12. Are there any benefits to passengers when the windows are open?

Yes, opening the windows can provide passengers with a better sense of airflow and connection to the outside environment. It can also help alleviate any feelings of claustrophobia for some individuals.
