a jettison system similar to those on the McDonnell Douglas MD-80 (for its tail) on your male docking system can be useful as well, so you pull a lever when you're about to release the payload
Also it's important to put your mask on first and then help others because at those altitudes you can pass out within seconds or get hypoxia. So don't be the hero and put your mask on before helping others.
Also the TUC chart (Time of Useful Consciousness) you usually have 30 seconds to two minutes, lots of factors play into it. If you're at 45,000 feet you're screwed you only have 9 to 15 seconds
I have the same question. Basically I was opening this video and hoping to find an answer to this question. Anyway, it's a great video, still learned few new things.
The hoses are long enough for you to not rip the hose as you can see they swirls at 11:05. That is the fully-deployed position after you have pulled the safety pin out of a cylinder oxygen in which will lengthen the hose as they are initially short due to a lanyard tied in between the safety pin and mask at 7:07. This also can help the maintenance crew to indicate which mask has been used so they can dispose it.
Fun video Joe! Most people don’t even listen to the flight attendants during their briefing, so hopefully more people will remember the great information in your video. Great job covering such an important topic 👌🏻!
I couldn't understand the attendant anyhow. 3:21 - 3:25 ?V? " "Jet airliners automatically deploy the passenger oxygen masks, "from the paum above your seat." " What's she saying? Can't be compartment or panel just really heavily accented, cant tell. Maybe accidental word mash.
Pardon the pun but your video about the emergency oxygen system is like a breath of fresh air 😃. I definitely enjoyed learning about this important system since it is always good to know how to use it, and to understand how it works :) . I am a “newbie” passenger so I have not really flown that much but learning about this takes the fear element out of flying more than 15,000 feet above the ground :) .
We used to use a similar thing on US submarines. When oxygen gets low, and for some reason we cannot take in fresh air, or if the o2 generator goes down, theres oxygen candles we can burn for oxygen. There was also a naval firefighting device called an OBA (oxygen breathing apparatus) used to provide o2 during emergencies. Same idea. A canister the insights to create oxygen. Damn thing sucked because it was worn on the chest. Thanks for bringing back memories of the boat Captain Joe.
I studied chemistry in high school and I understand the reaction taking place, I just have a hard time wrapping my brain around a reasonably hot exothermic reaction producing oxygen without simultaneously setting everything else on fire. Kudos to the engineers who designed this system!

Great video Joe, you have a great way of explaining things. As both a pilot and a paramedic, I’d like to clear up one point. You said that at FL180 “there is only half the amount of oxygen left in the air” compared to sea level. To be precise there is still nearly exactly the same amount of O2, 21%, in the air at that altitude and even much higher. The partial pressure of the O2 compared with the other gasses present is what is lowered at you ascend. This means that the lungs cannot absorb the oxygen as efficiently at higher altitudes and you will start to become hypoxic. Your body will stop functioning correctly (and very quickly at higher flight levels) unless you correct for this. Two ways to correct: increase the pressure of the gasses by pressurizing the cabin (the normal way of doing things) OR, increase the just the oxygen gas pressure by changing its concentration. The latter being easily accomplished through the supplemental chemical O2 mask system or by the use of bottled 100% O2. I think we thank Boyle’s Law for this. :-)
I love how often you ask for people to show some respect for the crew members because yes, people are usually doing everything else during the safety demonstration, except paying attention to the procedures that are being shown. Also, your videos have a lot of relevant information even for people who already work in this area. Thank you
This was a very good video! I am a frequent flyer and ever since I was told that we did not have flotation vests but had to use our seat cushions instead, I always pay attention to the security demo. You never know what changes they come up with! Happy flying!
Great video Captain and thank you for the explanation! A small correction from a physician: the problem with high altitude is not low oxygen amount but rather a low partial pressure of oxygen. The partial pressure of oxygen is a very important concept in lung physiology as it healps oxygen dissolve in the blood and finally be taken by the hemoglobin. At high altitudes the partial pressure of oxygen drops graduallly as we ascend, thus the oxygen we breath normally will not dissolve into our blood easily as if we were at the sea level where the partial pressure of oxygen is about 760mmHg.
Yes, that is true, but is it also true that the air is "thinner" at higher altitudes, meaning that there are fewer oxygen molecules per unit volume than at sea level? That is, the air molecules, including oxygen, are farther apart at higher altitudes as compared to sea level.
I used to have a lot of personal anxieties and issues with flying. Watching your videos (not this in particular but many of them) has helped me a lot. Thank you Captain Joe! Air travel is much easier for me now.
Great video, even an old dog like me (more than 41 years and more than 22,500 hours of experience) is learning a lot from your videos. The CL-30 corporate jet that I fly now has bottled O2 for the pax as well as the crew as it is required for oceanic trips. We have charts that we have to refer to when planning an ocean crossing to be sure we have the required O2 for the passenger load. Keep the great videos coming.
If I were to correctly remember a quote from the podcast/radio series 'Cabin Pressure' "Aeroplane safety procedures may change from time to time. And this one, flight to flight!"
For those wondering: it's quite easy to generate pure oxygen mechanically using pressure swing adsorption (same thing as machines used by people with lung disease), and the aircraft could be left unpressurized and made thinner and lighter. However, the extra oxygen machines would cancel the weight savings, and the tiniest spark would turn the plane into an instant fireball.
Actually thinking about becoming a piloto after i finish my current business degree. Just found this Channel and i can't stop watching. Really interesting stuff. Thanks and greetings from Spain.
The Sodium Chlorate formula is wrong. There should be a subscript 3 on the oxygen, otherwise the reaction would not work, because there wouldn't be enough oxygen left after the iron has oxidized.
The oxygen cylinder has one "detonator" connected by cords to every mask in row. So, if one person pulls mask the oxygen will flow to all masks (they are all connected in one junction).
Scuba divers rarely use oxygen tanks unless they are engaged in technical diving requiring decompression stops. I’d say gas tank is more appropriate term here. Diving with pure oxygen can cause serious problems due to hyperoxia and that is one reason why majority of divers dive on air. Otherwise, love your channel and keep up the good work! Br: Scuba diver and a wannabe cpl student.
Hi Joe, once again a great video! Just one thing: at scuba diving you never ever use oxygen in the bottle, it‘s just compressed (natural) air, about 200bar. 😀
Great Video Captain Joe. There is a little mistake in the chemical formula at 5:20. Sodium chlorate has the formula NaClO3. NaClO is sodium hypochlorite.
The bag has another purpose, to provide a high surface area to cool down for the exothermic chemical reaction used to release the oxygen. Breathing in warm gas instead of hot gas is much more comfortable.
Absolutely great video! I'm paramedic and doctor so I'm very interested in vids like this. And info about burning smell! It's SO important! I imagine that panic reaction is very common in situation like this, when you have to wear mask and when you feel burning smell in he same time this reaction can be extreme. Thank you :*
I doubt it. The engineers likely took both extremes - nervous passengers giving weak pulls and strong passengers really yanking the thing - into account, so I doubt it'd fall unless you really tried to pull it out.
Great video! The only issue I have, is the chemistry: the formula of sodium chlorate is NaClO3 (not NaClO), thus providing excess oxygen for the presumed reaction NaClO3 + Fe -> NaCl + FeO + O2 No wonder, this reactio creates a lot of heat. Your video makes a lot of sense. Many thanks for that!
I'm 13 and I cought the aviation bug about a year ago I've been upsest with planes ever since. My family took me to the airforce meusam in ohio and I fell in love with planes!!! My favorite one there was the b-52 I love the big jets I want to fly a 747 when I'm older
I always pay attention to the safety demonstration, because... I only have 1 thing in my head... people's safety, my family rarely pay attention to it, they usually fall asleep during that, so.. that's why I need to watch it carefully, to be the dependable one. Everytime I get into the plane, 1st thing that I do is that I look at the emergency exit routes (where the doors are, the emergency floor lights, etc), and the safety card. Like.. those are a MUST.
I used to have to regularly take the commuter flight from Birmingham (UK) to Dusseldorf (DE) and am very proud of the fact that I ALWAYS paid attention to the flight safety announcement. The emergency oxygen system should be programmed so that it simply does not deploy to passengers who were looking at their phones instead of watching the flight attendants.
That is fo most of the A/Cs: on the B787 the O2 is not generated chemically in situ, hence you don’t need to pull down, and the duration is much longer. The generator reactants may vary for organic reactants, and note: NaClO is sodium hypochlorite (bleach). Sodium Chlorate, which is a strong oxydizer is NaClO4
Great video CJ! Why is it that some airlines decide to 'delete' the engine manufacturer symbol/branding? Is it purely cosmetic, like options on a car? Or is there a large fee associated with this? I'm not sure why this popped into my head, but it did.
This was the actually a very informational one. You got it right i too neglect the safety demonstrations :P Will be more attentive from now on. Good one Joe
It was very informative video. I want to be an airlinepilot just like you and my dream bird is b787. Its been a while that you started to be my instructor. Always grateful to you joe!
Hello captain Joe love your informative videos. My son too is pilot captain ATPL and flies the Boeing 777 300 ER for Emirates. He is from south africa Johannesburg. Lives in Dubai now. Keep well enjoy watching you.
Hey Captain Joe. Great video but it’s a little bit off.... I’ve been in Air EMS for years and we are all highly trained in flight physiology and gas laws. You stated that there is less oxygen in the air as you ascend in altitude. This is not true. It doesn’t matter whether you are at sea level or at FL600 there is roughly 21% oxygen in the air also know and .21 FiO2 (fraction of inspired oxygen).The reason why you have a problem with hypoxia as you ascend, is actually due to the partial pressure of oxygen. As you ascend the partial pressure of oxygen (and all of the gases in the air), decreases. This is know as Boyle’s Law. Essentially this means that the oxygen molecules become further and further apart which means that you inhale fewer oxygen molecules. This causes hypoxia because the partial pressure decreases. This is the exact reason why we pressurize the cabin, so that we can exert atmospheric pressure ( within the cabin), forcing the partial pressure of O2 to remain at a safe level. As you utilize the emergency (supplemental) oxygen, you increase the partial pressure of oxygen to near 100% or an FiO2 of 1.0, and your hypoxia ceases. This is how it actually works.
also CO and CO2 are more easily taken in by the body . also one of the reasons why you can not breathe pressurised AIR for to long as NO will get in your blood more easily then O2. we are made for sealevel... ( more or less)
Well technically if the air pressure drops, but the fraction of oxygen in the air remains constant, there really is less oxygen in the air. This however does somewhat imply that other gasses remain constant, but of course they don't.
You Could of not timed this any better, currently covering the Air Con and Oxygen systems on my Aero engineering course at College, this video is going to help me with my assignment, thanks Joe
ATR 72 and Falcon dassault business jets uses Oxygen bottles for passenger, actually the same as the pilots, but it's possible for the pilots to close the supply to the passenger.
Don't think of the mile high... It's lesser than you think, unless it's one of the stark's party bus back in the day... Or just the business private plane
There is a minimum of two oxygen bags in each lavatory? Sounds like engineers planned for people being in the mile high club.
I thought that too for a second, but it's for infants.
Or they are, more boringly, there with their young children.
Or if one doesn't work and you are unable to get to your seat on time. I'm not judge, I also have a dirty mind...

You stated that there is less oxygen in the air as you ascend in altitude. This is not true. It doesn’t matter whether you are at sea level or at FL600 there is roughly 21% oxygen in the air also know and .21 FiO2 (fraction of inspired oxygen).The reason why you have a problem with hypoxia as you ascend, is actually due to the partial pressure of oxygen. As you ascend the partial pressure of oxygen (and all of the gases in the air), decreases. This is know as Boyle’s Law. Essentially this means that the oxygen molecules become further and further apart which means that you inhale fewer oxygen molecules. This causes hypoxia because the partial pressure decreases. This is the exact reason why we pressurize the cabin, so that we can exert atmospheric pressure ( within the cabin), forcing the partial pressure of O2 to remain at a safe level. As you utilize the emergency (supplemental) oxygen, you increase the partial pressure of oxygen to near 100% or an FiO2 of 1.0, and your hypoxia ceases. This is how it actually works.
also CO and CO2 are more easily taken in by the body .
also one of the reasons why you can not breathe pressurised AIR for to long as NO will get in your blood more easily then O2.
we are made for sealevel... ( more or less)
Yea that’s true, but joes explanation is simple enough so others can follow and understand
Joe used the effective oxygen, which means how much oxygen would be in the air, if it was at room pressure.
Well technically if the air pressure drops, but the fraction of oxygen in the air remains constant, there really is less oxygen in the air. This however does somewhat imply that other gasses remain constant, but of course they don't.
So at higher altitudes there is not less oxygen in the air, but less air in the space (and less air in your lungs) which means less oxygen?
Thanks
Why was he smiling so much after inhaling from the mask? Was that N²O?
Probably getting a bit of hypoxia... Incorrect wearing
You Could of not timed this any better, currently covering the Air Con and Oxygen systems on my Aero engineering course at College, this video is going to help me with my assignment, thanks Joe
CONCORDE444 good timing
Could be Duchtpilotgirl voice in oxygen mask briefing
nope, you're wrong :P
nope, it's his wife
@@Lirani87 he's single as long as i know
To me it sounds like Carolin from the ‘can a passenger land an airplane’ video but that’s just my thoughts.
For as many times as I've flown, I didn't remember the bit about having to tug on the tube to get the thing started! Good info!
I never want to see that mask in a flight while traveling!
Scuba divers use compressed air , NOT oxygen . this is the only error I found. GOOD JOB.
Ahhhh, I crashed my 100th plane on x-plane 11 due to flying slow
ATR 72 and Falcon dassault business jets uses Oxygen bottles for passenger, actually the same as the pilots, but it's possible for the pilots to close the supply to the passenger.
"There's a minimum of 2 oxygen masks in each lavatory." What would 2 people possibly be doing in the lav at the same time ;)
Oh, I don't know, perhaps helping their little child out? But no worries, we all had the same thought. ;-)
Don't think of the mile high... It's lesser than you think, unless it's one of the stark's party bus back in the day... Or just the business private plane
yeah, not many people know that you can change a child's diaper also in lavatory instead of doing this on the table in the cabin
Happy Days, thank you Captain 🧑✈️ Joe 🙏✈️✈️✈️
Hello There Captain
Thanks, Joe - great video which answered all the questions I've always had about how the oxygen masks work!
Hi captain...
Just found your channel and your smile is infectious. Subscribed for sure.
