Cabin crew ask for window shades up during takeoff and landing so everyone’s eyes are already adjusted to the outside light if an evacuation is needed. Open shades also let the crew spot fire, smoke or debris beside an exit before opening a door, and let rescuers see into the cabin. It is standard airline procedure, not a passenger preference.

It is the one instruction that seems least connected to safety, which is exactly why it gets ignored. In practice, an open shade is one of the cheapest pieces of safety equipment in the cabin.
Why Do Cabin Crew Want the Shades Up?
Three reasons, and all of them are about information. First, an open shade tells you and the crew what is happening outside your row: flames, smoke, debris on the wing, or water instead of tarmac. Cabin crew are trained to assess conditions outside a door before opening it, and a cabin full of open windows gives them far more of the picture than a small viewing port alone.
Second, light travels both ways. Emergency responders arriving at an aircraft can see into the cabin through open windows, which helps them judge where people are and how urgent the situation is. Third, if an evacuation begins, nobody wants to be discovering the outside world for the first time while unbuckling a seatbelt.
What Happens to Your Eyes in a Sudden Evacuation?
Human eyes adjust between bright and dark conditions slowly. Moving from a lit cabin into darkness, full adaptation can take twenty minutes or more, and the first seconds are the worst. An evacuation is measured in seconds, so the goal is to have your eyes already matched to the light level you are about to step into rather than adjusting on the slide.
That is also why the cabin lights are dimmed for a night departure or arrival. It is not mood lighting. Dimming pre-adapts everybody’s vision to the dark outside and makes the emergency floor-path lighting and illuminated exit markers far easier to pick out. On a bright day the logic runs in reverse, with the shades letting daylight flood in so the cabin is not suddenly plunged into contrast.
Why Only for Takeoff and Landing?
Because that is where the risk sits. Boeing’s long-running statistical summary of commercial jet accidents has consistently shown that takeoff, initial climb, final approach and landing account for the large majority of fatal accidents, even though those phases occupy only a small slice of the flying time on a typical trip. Pilots have their own shorthand for it: the first few minutes after takeoff and the last several before landing.
So the cabin is configured for the unlikely event during those windows and relaxed afterwards. Once you are established in the cruise, you can close the shade, recline where the seat allows it and sleep. Crew will usually ask for shades up again as the descent begins.
What Else Is on the Same Checklist?
Every item the crew calls out before departure belongs to the same idea: a cabin that can be emptied quickly, with nothing loose and nothing blocking the path. None of it is busywork.
- Tray table stowed and latched: keeps your route to the aisle clear and stops a hard edge meeting your abdomen in a sudden deceleration.
- Seat upright: gives the passenger behind you room to get out and puts your body in a better position to absorb impact forces.
- Bags stowed properly: anything loose becomes a projectile, and anything in the aisle becomes an obstacle.
- Seatbelt low and tight across the hips: the belt should sit on bone, not on your stomach.
- Cabin lights dimmed at night: eye adaptation, plus better visibility of floor-level escape path lighting.
- Headphones off on many airlines: so you can hear a shouted crew command without a pause to remove them.
Read as a group, the checklist is really one instruction restated several ways: be ready to leave, be able to hear, be able to see.
Is It Actually a Rule, or Just a Request?
It is a procedure rather than a single worldwide law, which is why practice differs. Airlines across India, much of Asia, Europe and the Middle East ask for shades up as a matter of routine, while some carriers elsewhere, including in the United States, do not make the same request. That inconsistency is about company procedure, not about the physics changing between continents.
In India, cabin safety procedures form part of an operator’s manuals accepted by DGCA, and shades up for departure and arrival is a standard part of them on most carriers. The bit that is not optional anywhere is compliance: passengers are required to follow lawful crew instructions, and refusing to do so falls squarely inside DGCA’s unruly-passenger framework. If a crew member asks, just slide it up.
Common Questions
Is it illegal to keep the window shade down during takeoff?
There is no single global law about shades themselves. What is enforceable is the instruction: if cabin crew ask you to open it, that is a lawful safety instruction, and repeatedly refusing crew instructions is treated as unruly behaviour under DGCA’s framework in India.
Why are the cabin lights dimmed for a night landing?
To let your eyes adapt to the dark before you might need to move in it, and to make the illuminated floor path and exit signs stand out. Bright cabin lighting against a dark exterior would leave everyone temporarily blinded at the worst possible moment.
Can I close the shade once we are in the air?
Usually yes. Most airlines only ask for shades up during departure and arrival, so the cruise is yours. Expect the request to come round again as the aircraft starts its descent, and on a daytime long-haul the crew may ask for shades down mid-flight to help people rest.
Why do some airlines never mention window shades?
Because it is set by each airline’s own cabin procedures rather than by one international rule. Carriers that skip it are not being careless, they simply weigh the same risk differently. Follow the crew you are flying with.
What about the electronic windows on a Dreamliner?
Aircraft with electronically dimmable windows have no physical shade, so the crew set the windows to their clearest state for takeoff and landing and can control them centrally. The intent is identical: a clear view out during the critical phases.
Does an open shade help spot problems in flight?
It can. Passengers with a wing view have flagged issues to crew before, and crew themselves use cabin windows to check external conditions. It is not a substitute for the flight deck’s instruments, but an extra pair of eyes has never hurt anyone.
