Why Airplane Seats Must Be Upright for Takeoff and Landing

The few inches of personal space taken up by a reclined airplane seat are some of the most valuable territory in the world. Wars have been waged over them. Much effort has been devoted to conflict resolution too (and, in case you’re wondering, there is a less obnoxious way to recline your seat).

But regardless of which side of the should-you-or-shouldn’t-you debate you come down on, we can all find common ground during two stages of every flight: those moments during takeoff and landing when we are all asked to keep our seats “in the upright and locked position.”

While it may seem like just a few inches of recline, it turns out that they are key when it comes to safety during takeoff and landing. The Federal Aviation Administration (FAA) and other global governing bodies require airline passengers to bring their seats to the “upright and locked” position during critical stages of flight. Being chastised by a flight attendant over an inch can seem petty, but like most other safety protocols in aviation there is a good reason behind it. The problem: It’s rarely explained properly or simply. That’s why people think it doesn’t make a difference.

Here’s why following instructions can be key for safe air travel in the unlikely event you are in a real emergency.

Airplane seats are designed so that when they are in a fully locked position, they provide strong structural support. You may have noticed this if you’ve been in a malfunctioning seat that still reclines after being placed upright. If an aircraft starts to brake (at high acceleration, especially), the seat is designed to withstand that force. But when not fully upright, even by just a hair, the seat could jerk forward or backward with tremendous force and velocity, causing injury not only to the passenger in that seat but also to anyone behind them. Seat belts aren’t enough in a situation like that; since they only go across your waist, your torso and head could be jerked around dangerously.

Another key reason why seats need to be fully upright and locked is so that the people in the row behind you can have clear access to the aisle for a swift exit. If a seat were to recline suddenly (or even break) without the ability to go forward, it could impede the exit of passengers in the row behind. Aircraft designers don’t even take a chance on that happening around exit rows. This is why seats directly in front of an exit row do not recline at all, as these would be key points of egress.

Planes are designed to allow for a full evacuation in less than 120 seconds even if only half of the emergency exits are usable. This may seem shocking, but that design is responsible for saving many lives in real emergencies. For example, when an Air France Airbus A340
