Why do we dim the cabin lights for T/O and landing?


hi everybody but it wasn’t mentor and yet another video podcast as always I hope you’re all doing absolutely fantastic out there today on the podcast guys we’re going to be talking about why do the cabin crew dim the lights during landings and takeoffs when it’s dark outside and also why do you have to open the window blinds and stow your tray tables so stay tuned [Music] [Music] okay in order to cover this in a proper way you have to understand how we in the airline business three big things okay why we do certain things and basically anything that you hear us do anything that you see us do has its basis its foundations in safety okay so when we ordered the cabin crew tell you to do something you can be absolutely sure that whatever it is they’re telling you to do the reason behind it is your own safety and the safety of all the passengers to see that all around you alright so indicate of cabin crew dimming the light during takeoff and landing in the hours of darkness it’s a fairly obvious reason for that I guess that most of you guys have already figured it out but what what we’re trying to do is let your eyes adopt to the relative light that is outside of the aircraft in case the aircraft has to stop during the takeoff and we have to do an evacuation now in order for you to understand this fully I propose a little bit of an experiment foil so if you’re in your house and you into the toilet run down all of the lights and the rest of the house put the lights on full blast in the toilet okay and then once your eyes have adapted to the light open the door and try to run up to the bedroom all right see what happens what’s going to happen is that you are going to be completely blinded to get out your eyes are not adapted to delay through the darkness outside it’s going to take you several seconds for the eyes to adapt to it and then you’ll be able to move exactly the same thing is going to happen if you have to evacuate an aircraft if it would be light inside and complete darkness outside now when we evacuate an aircraft we work on having all of the passengers outside of the aircraft within 90 seconds okay 90 seconds of the beginning of the evacuation everyone has to be outside and that is if part of the emergency exits are blocked for whatever reason okay so there is absolutely crucial that none of you hesitate for even a second when you are jumping out to the slide to going out over the other wing access project so that’s adapting to light you’re all the way that your eyes have adapted to like that’s going to help you to get quickly out through the door and that is exactly the same reason of the same reason we are telling you to stall your throat and your tray tables because everyone even the one sitting next to the window have to get out into the aisle then back and an out to the emergency exits or forward to the to the exits that you can you know in the front of the aircraft on the back so a tray table for example might be in the way and it’s going to slow the evacuations out another benefit of dimming the lights is also the emergency lighting system that we have which is up here right this is an automatic system that will come on in case the aircraft loses power okay the layer of service is AC power and and it leads emergency exit lights are armed then the evacuation lights are going to come on automatically and of course if it is dark in the cabin it’s dark outside you’re going to see these lights much more efficiently window shade what about window shades done people without well it’s similar okay first of all it will adapt this you will see what’s going on outside which is really important so for example we do not want to evacuate the air prophet we have for example a fire outside of the aircraft now it’s important that we initiates the open so that you and the cabin crew can see what’s going on outside of the aircraft so that they can direct you away from a potential danger so that’s the reason for that and also another thing is in case the firefighters would come to the aircraft they will want to be able to look inside to see what’s going on inside it was fire where there are survivors of stuff like that and they might use the windows to do so so that’s the reason why the window shades are always open as well well guys I hope you enjoyed that one now that just goes to show exactly what I said before they you have to know what to do you have to listen to the cabin crews come on and therefore for everything you know there’s nothing that the chemical will tell you to do or not to do that it’s not grounded in your own safety and that’s really the point I wanted to make with this video and as always guys I hope you’re enjoying this I hope you’re following me on Facebook on Instagram and I hope you get the app to the month radiation apps and join up and discuss things in the indie chat forum for now I wish you all a a ballute Lee Sun tastic day and I will see you next time bye bye [Music]

  1. Woow this is the very helpful video I have take before a Airplane ride before sincemy first flight was in 2008 "Thank you pilot" I can understand your question cvery clear. So yeah i had liked this video ☺

  2. we interrupted this flight to bring you a video explanation of why (the hell) everything has to take forever. We are confident that you would be totally satisfied with our flight once you hear the reason behind every infuriating little thing that we make you do. Enjoy!

  3. am I missing something here, iv never been on a plane that dimmed the lights for take off and landing. In fact the cabin as always been lit and the windows asked to be open. as to prepare your eyes for the bright outside sun in the event you have to evacuate the plane on landing / crash landing .

  4. great channel, thank you very much! i wish i had such important content in my early flight sim days around 1996. i had to figure all questions out for myself, which could take months or even years to answer it.

  5. So the cabin lights are dimmed, my eyes have adapted to the darkness, but then the emergently lights come on, and now I'm blinded by them, but soon my eyes adapt to the energency lights, but now it's time to evacuate into the darkness and can't see a thing.

  6. so if the plane crashes while take off or landing, people can see where there is fire and see how it comes to fry them. total value for money they charge

  7. This fairly obvious. Anybody who does nightshift knows that you can see more if the lights are off or dimmed.

  8. To the maker of this clip Your experiment is what the mythbusters done for a pirate myth h regarding eye patches it's to help the rod cells in the to develop the pigment that helps with night vision

  9. Its so that your eyes are use to the dark conditions if you have to evacuate quickly in case of emergency if the cabin power fails.

  10. Ah, I don't think so… I took-off during daylight, bright sun outside and they dimmed the lights. I think it's to reserve electrical energy for use on other systems during take-off and preventing a slight unnecessary shortage somewhere else. Then, it would make more sense to me dimming the lights during take-off on a bright sunny day.

  11. Why is the dash always so high. One can barely see over it. Seems like that could be a hazard when taking off and landing.

  12. I've always wondered so every time in landing and take off I'd forget to lift blinders, but from now on I'll always remember that. Thanks

  13. "anything you see us do has its basis, its foundation in safety"

    I bet Ryan Air are laughing their heads off at that statement

  14. Why aren't the lights off during the whole flight time when flying in darkness? In case of emergency will the pilots care to turn off the lights? Sounds pretty inconsistent

  15. Absolutely brilliant. Passenger understanding is like the holy grail. This video may very well save lives some day.

  16. "The reason behind it is your own safety"–except for the idiotic "Turn off your electronic devices" we had to live with for years. https://youtu.be/JYAq-7sOzXQ

  17. I just went to  the app store to download the IOS version of mentourpilot.  It wasn't available.  Reason is?  Great website you have by the way.

  18. I learned something today. Thank you. I have wondered these exact things for many years. They make sense. I would however like to know why they don't make the cabin windows bigger on airliners. To see straight out always required me to hunch over uncomfortably, and look up really hard. I know there is a view below the plane, but many people enjoy the landing and takeoff, and these low windows are awful. Besides, wouldn't it be easier for firemen to look in if the window was bigger?? (referencing the reason we open them from this video)

  19. Is the window shade thing a company/regulatory agency (I.e. The FAA or it's counterparts in other countries) policy? I've only flown a few times within the U.S., and none of the flight attendants said anything about having them up during takeoff or landing. Many of them were down from gate to gate.

  20. It doesn't actually make it feel especially safe when everything is about what can go wrong and what you do if it goes wrong. When you drive a car, you don't think about every single thing that can go wrong. You just drive to where you need to go. In an aircraft you constantly focus on things that can go wrong and you have to have a backup for everything. To me that gives a very pessimistic view of aviation, and it makes it feel extremely unsafe. It is like you don't even believe yourself that you can fly an aircraft without something going wrong, because that is where you attention is all the time.

    Imagine if you had to go through several cheklists every time you needed to drive your car. If it neded to be constantly serviced and you had to have backup and emergency plans for everything. In that case I would not even dare to drive a car.

  21. It makes sense not to use an exit that would expose the passengers to hazards like fire, debris, etc. But what happens if all of the exits are blocked by such hazards and the cabin is on fire? Do you just evacuate through whichever exits are relatively less dangerous and hope for the best?

  22. If I may ask a question here, there was one time when I was flying from KUL to PEK, it was a midnight flight, and mid flight we were instructed to close the window shade of the right side (or left, can't remember but definitely only one side), what would be the reason to do so since it is a night flight and the cabin light was still on?

  23. I wish they had a short version of these reasons in their scripts: “please put all tray tables up for takeoff so that passengers can access the emergency exits efficiently and the Capitan will dim the lights to allow for your eyes to adjust to the darkness in the event of an emergency.” Seat-belts are obvious.

  24. Well on my landing at Nice LFMN the cabin crew didn't dim the lights , couldn't record the landing without the reflect of the window and it could be dangerous too as you said in this video , the runway is short (2,570m) , the plane came from Switzerland so it couldn't benefit of a long approach and the airport is built over the water.

  25. In seagoing service, military and civilian, we are taught you don't gain basic Night Vision until 5 minutes, and not fully for 15 minutes. For some reason, it is important for some of the older "veterans" to claim it is instant for them – that's just being macho. There is some basic and extensive research and testing behind those numbers. Prior to going on watch on the bridge at night, I'd get up there early and just hang out as my vision adjusted, The bridge is blacked out – lights are off or dimmed and/or partially masked, always red (which affects Night Adapted Eyes the least, although a certain blue is being used on a test basis). The military stresses memorization of the bridge and all controls, for emergencies or just if your night vision gets interrupted – as it used to be by smokers lighting up, or if someone hits the regular white lighting by accident or even for a special purpose. In WWII, the Navy issued lookouts red goggles to wear for 15-30 minutes before going on watch at night.
    If the only light is a few dim red ones, and some dimwit makes an entry in the "wake-up log" in red ink, you can't see it. Got chewed out by that dimwit – and the rest of the bridge watch was laughing at him.
    More of your science "education"! Physics as applied to the human eye. You also see lights on the sea farther and sooner if you use your peripheral vision. Another bit of physics applied to the human eye. You teach yourself to do it until it's automatic. On boring watches, it becomes a competition; another teaching mechanism. Science of phycology? Sometimes you beat the radar.

  26. 1:45 Broken leg/arm anyone, you are suggesting one dangerous experiment 😉
    Well, no-go, there is just one 3W led bulb, and even that one got kinda old and dim 😉

  27. They do something similar in the navy, they use red lights inside during the night so if you suddenly have to go outside, you'll be able to see what you're doing

  28. why they dim – its obvious, but why they switch bright light during night flights while servicing !?( thats disaster…. majority people are sleeping…. mild light is enough for food service

  29. why there`s no smell in toilet…even right after someone used it,there`s no bad smell?is it because of the pressure?

  30. Mr Mentour Pilot I don't know what your Name is but Thank you for sharing this Even though I'm afraid flying but thanks for sharing

  31. I saw the title in Swedish so I thought you were going to speak Swedish… got disappointed 😂
