Many passengers wonder why there are so many safety regulations when flying, and why flight attendants constantly remind you of what not to do during takeoff and landing.

Let's explore some of the hidden safety knowledge onboard an aircraft.

1. Why should window shades be opened during takeoff and landing?

The first 6 minutes after takeoff and the final 7 minutes before landing, known as the "black 13 minutes," are the most critical periods during a flight, as emergencies are most likely to occur.

In the event of a power outage, especially during takeoff and landing or on the ground, failing to open window shades could plunge the cabin into darkness, potentially causing panic and hindering passenger awareness of external conditions or emergencies.

Therefore, it's necessary to keep window shades open during these phases to facilitate communication with flight attendants and reduce the likelihood of accidents.

2. Why should seats be in the upright position?

During takeoff and landing, which are critical phases of flight, passengers must have their seats in the upright position. This is essential for facilitating rapid evacuation in case of an emergency landing.

If seats are reclined, it could impede the evacuation process and delay passengers' ability to exit the aircraft efficiently.

3. Why are lavatories off-limits during takeoff and landing?

During takeoff and landing, aircraft are most susceptible to turbulence caused by passing through clouds and atmospheric disturbances.

Attempting to use the lavatory during these times increases the risk of injury due to severe turbulence, such as hitting the walls and sustaining fractures or other injuries. Therefore, lavatories must remain off-limits to ensure passenger safety.

4. Why are infant safety belts provided?

In the event of severe turbulence or an emergency, adults may be unable to hold onto infants securely, potentially leading to the infant falling or being propelled within the cabin.

Infant safety belts are provided to secure infants to adults during these critical phases, minimizing the risk of injury.

5. Why can't luggage be placed under emergency exit rows?

Emergency exits are crucial evacuation points during an emergency. Placing luggage under these exits can obstruct access, impeding passengers' ability to evacuate quickly and efficiently. Therefore, it is essential not to place any luggage in these areas.

6. Why should headphones be removed during takeoff and landing?

Similar to other precautions during takeoff and landing, removing headphones ensures passengers can hear important announcements and instructions from the crew in the event of an emergency. Wearing headphones may hinder passengers' ability to receive critical information and respond effectively.

7. Why are power banks prohibited from being used once inside the cabin?

Power banks, also known as lithium-ion batteries, pose a fire hazard if they short-circuit or overheat. In the confined space of an aircraft cabin, particularly after takeoff, a fire caused by a power bank could have catastrophic consequences. Therefore, it is safer to refrain from using power banks once inside the aircraft cabin.

Safety is paramount, and everyone should adhere strictly to these regulations.
