737 Fire Protection

[@MV5LANDmusicproductions]

As a pilot for the 737-900ER, I have DEEP respect for your videos

[@ChrisBrady737]

Many thanks, glad you find them useful.

As an airport rescue and firefighting services member I want to thank you from the bottom of my heart; it may be sound strange to you but nobody is really interested ( and i mean all the involved parts) in learning or training in depth about the systems of an aircraft; in my job the only thing we do care about is extinguishing the fire which I believe is fundamentally wrong, so i cannot thank you enough for the extra valuable information you are providing. A Greek firefighter.

[@ChrisBrady737]

Thank you very much for your kind feedback. Most of the airport firefighters that I have met have all had some interest in aircraft, but as you say only a superficial understanding of the underlying systems and potential hazards. I am pleased that my videos can help in that area. Thank you also for your service in keeping crew, passengers and all airport staff safe.

Thank you for explaining this topic. Greetings from Poland

You are very welcome. Thank you for watching

[@petertwiss4215]

Thanks for the video! Just a couple of points that I remember: The Wing/body overheat was also a concern for a leak at the LE flaps because of the thermal heating of the front spar. Your pic of the LE flap fire wire puzzled me a little as I remember this corkscrewed around the duct (I could be thinking of a different aircraft though). Also the toilet bin flap which was sprung loaded so tight it felt like a rottweiler chewing your knuckles was on the classics a standard check for the engineers as it formed part of the bin seal for fire protection.

[@ChrisBrady737]

Glad you enjoyed it and thanks for your comments. Yes the waste bin lid was like Arkwrights cash register in Open All Hours!!

[@CraigKilcourse]

Brilliant work Chris. Love these presentations...better than Netflix!

Maybe you've heard this one. I've been told that the smoke detectors sometimes give false alarms in places like south america after the ground crew had applied insect sprays to the cargo hold. The guy who told me said these false alarms would always trip before takeoff.

[@ChrisBrady737]

Yes, I have had that happen to me in Turkey where they did the same thing. It is a known phenomenon, I probably should have mentioned it in the video.

[@medlevinger]

@@ChrisBrady737 maybe there is a KZbin option to add a text during the video. What you also can do, there is an option to pin the comment so it will always show first below your video, so guys who are interested in reading comments will see it first.

[@ChrisBrady737]

Good idea, I’ll look into it

[@dannottingham3786]

Thanks Chris, I've been off the NG for about 5 years, now going back on and your videos help prepare for ground school. Excellent stuff.

[@ChrisBrady737]

Hi Dan, That is great to hear - Welcome back!

[@yazanf.mishal8926]

wonderful presentation, very insightful even for low experienced pilots i would highly recommend it!

[@ChrisBrady737]

Thank you for your kind comments.

Excellent work,captain! Congrats!

Thank you

[@christian.xavier.villagran]

I became an A&P this year and my dream is also to fly, so be surprised that you may have some A&P also learning from your amazing videos. Thank you

[@ChrisBrady737]

That is great to hear, glad you find the videos helpful.

[@telescope64]

Thanks for taking the time and effort to make this video,there are lots of great tips!

[@ChrisBrady737]

You are very welcome, thanks for watching

[@2Tool4School]

These are always fantastic. Looking forward to one on Hyds!

[@ChrisBrady737]

Thank you. I am working simultaneously on hydraulics and flight controls. Not sure yet which I will release first. FC will probably be a 3-part series

[@lewishammett4534]

Forward Lav comment is quite funny and true ha

[@ChrisBrady737]

Sadly yes!

[@Srinathji_Das]

That was a really cool video! 👍

[@ChrisBrady737]

Thank you!

[@vinaymalik2986]

Good as always. But you didn’t explain much about the cargo electronic unit

[@ChrisBrady737]

Sorry but I can’t cover everything otherwise the videos would be too long.

[@vinaymalik2986]

@@ChrisBrady737 yes sir you are right. Actually I like your way of explanation, that's why I wrote this.

[@cesarcabezas3979]

amazing videos .thanks Chris really good job .

[@ChrisBrady737]

Glad you liked them, more to follow.

[@argfaa]

Thanks for the excellent explanation!! If you have a second fire in the other cargo compartment, Does the system work in the same manner? the remaining time of the Halon stills works? Greetings from Argentina

[@737simguide2]

Thank you, Chris. Great content as always 👍

[@shaoyuli716]

hello Chris，I have a question. How does the wheel fire detector using battery bus to work? Thank you so much.

[@ChrisBrady737]

Sorry, I don't understand your question.

[@marcosainoza2788]

Hi Chris, I have a question please, the DETECTOR FAULT light in the cargo panel says that one or more detectors in the loop(s) has failed, so how do you know you still have detection operative or inoperative in each hold? you select loop a or b in order to know which one has failed? and another question if so, and you are able to know that you have no loops operative at all you must land asap or you could continue normal operation? i hope you understand the question, english is not my mothertongue. thanks

[@ChrisBrady737]

Yes select A or B. The QRH does not direct you to land ASAP with a detector fault, so it is the Captains or companies decision based upon the circumstances.

[@guritche]

I have no experience with the 737, just studying the FCOM and supplementing with these fine videos. At 25:18 I am confused. Is it different for the Max? The FCOM I've got says the second Low-Rate Discharge bottle fires 15 minutes after the High-Rate bottle.

[@ChrisBrady737]

For aircraft with the Dual Cargo Fire Extinguisher bottles option on the MAX the second fires 15 minutes after the first; on NG the second fires 60 minutes after the first and on the BBJ the third fires 60 minutes after the first two.

[@mylifeisdope916]

i found one of those bottles on a beach. can they trace which plane it came off?

[@ChrisBrady737]

They probably could as most components have a data plate on them.

[@mylifeisdope916]

@@ChrisBrady737 seemed like this one had been floating around the ocean for some time as its sensors were a bit smashed up. It did have hand engraved numbers on the various parts. Quite interesting

Awesome :)
