Airbus FIRE PROTECTION system!!! AIRBUS SYTEM KNOWLEDGE explained by Captain Joe


Dear friends and followers,
welcome back to my channel and lovely greetings
from the Airbus A320 simulator at the TFC Flight Training Centre
here in Essen, Germany. This is another Airbus introduction video and I’ll be giving you a basic explanation
of the A320 fire protection system. So let’s get started! The aircraft fire protection system
consists of a fire and overheat detection and extinguishing system
for both engines and the APU. Besides that, there is a smoke detection
and extinguishing system in the cargo compartments
and the lavatories. Plus, a smoke detector in the avionic bay and portable fire extinguishers
for the cockpit and the cabin crew. So let’s take a closer look
at the fire extinguisher and detection system
in the engines and APU. Now each engine has
two extinguisher bottles, which electrically operate squibs
to discharge their contents and so does the APU,
except that with only one, has one extinguisher bottle. And the pilots control
and discharge both systems with the engine and APU fire panel
on the overhead panel. So both systems have a fire
and overheat detection system consisting of two identical
fire detection loops, A and B, mounted in parallel
and a fire detection unit, a FDU. The loops consists of three to four
sensing elements for each engine. One in the pylon nacelle, one in the engine core, and one in the fan section. And one independent sensing unit
in the APU compartment. So when is the fire warning triggered? When any sensor on the loop
is subject to heat, it sends a signal
to the fire detection unit and then triggers the warning.
[aural fire warning sounds] Or as soon as loop A and B detect a temperature at a preset level,
the warning system is triggered. If both loops should break
within five seconds, the system expects
that both loops got damaged by flames and also triggers the warning system. In case of one faulty loop, the other operative one takes over
and still protects the aircraft. Other than that, if the system detects an APU fire
while the aircraft is on the ground, it shuts down the APU automatically
and discharges the extinguishing agent. Okay, let’s take close look
at the fire switches on the upper level
of the overhead panel. The push button’s normal position is IN
and guarded by this red frame. [aural fire warning sounds]
Once a fire warning is triggered, the pilot opens the guard
and pushes the button. And as it pops out,
it sends a electrical signal that performs the following
for the corresponding engine. First of all,
it silenced the aural fire warning, arms the fire extinguisher squibs, closes the low pressure fuel valve, closes the hydraulic fire shutoff valve, closes the engine bleed valve, closes the pack flow control valve, cuts off the FADEC power supply
and deactivates the IDG, the integrated drive unit
driving the generator. Next to fire push button
are the two agent push buttons. So both buttons become active
when the flight crew presses the engine fire push button
for the affected engine and a squib light comes up in white, helping the flight computer identify
which agent is now ready to be discharged. A brief push on the button discharges
the corresponding fire extinguisher and DISCH lights up amber
when the fire extinguisher bottle is entirely empty,
measured by its bottled pressure. And then you have the TEST push button. This button permits the flight crew to test the operation
of the fire detection and extinguishing system
before each flight of the day. When the flight crew presses it, a continuous repetitive chime sounds, the master warning lights starts flashing, the engine fire warning appears
on the lower ECAM, and now on the engine panel
of the pedestal, the fire lights come on red. To perform this test correctly you check
that all necessary lights come on, the procedure is shown on the ECAM,
and that you cancel the aural warning by pressing
the master warning push button. And the same procedure applies
as you press the APU fire TEST button. Now in case of an APU fire, the pilot opens the guard
and presses the APU push button. And by the way, that’s not the only way you can shut off the APU
in case of a fire on ground. There’s an external APU panel
below the cockpit near the ground power supply connector. In case of a fire,
a warning sound can be heard and the ground personnel can discharge the extinguisher bottle from below
by pressing this button. So that was it for today. I hope you enjoyed

  1. Wird dieser fire loop detector warm und dehnt sich aus oder wird die Verbindung durchtrennt? Irgendwie habe ich das nicht ganz verstanden. Und woher weiß man das das Feuer nach der ersten Löschflasche wirklich aus ist?

  2. Cptn Joe, Sir. I enjoy your videos immensely . Your presentations are wonderful. You seem like a fine, down-to-earth young man and I wish very best for you and yours. I was a part 135 Capt decades ago (lite recep twins.) Other things got in the way, now am old man who remembers and learns from your videos. The future is in good hands

  3. Hey Captain Joe, why in the APU fire indicator there is a black label hiding something? Is it the overpollution button? XP

  4. What is going in with the Boeing 747. Airlines are getting rid of them like crazy. United already has a last flight plan.

  5. Captain Joe, love your channel. Amazing info. I have a question for you… Actually is more of what think about Flight MH370… case. Why can be possible the aircraft can´t be found. Thanks, and keep up the good work. Al

  6. Isn't it true that you need to warn the ground crew when testing the APU fire detection system so they don't hear the alarm and discharge the APU squib?

  7. Not right translation at 3.06, not "разряжает" , right translation is "приводит в готовность".

  8. Hi Joe, why do airplanes have such small wheels, they need to spin quickly and this little radius make them spin more for same speed on larger radius wheels, right?

  9. what is under that blacked out square below the fire push button/light at 4:53 ?
    (your fingers move over it, and it does show a digitally added black square… you even see SQUIB appear after his fingers move away)
    what are you covering up? "shut off chem trails"?

    i don't think you disperse chem trails though, in case you didn't get the joke

  10. Dear Joe sir did you make video on how to start preperation of pilot from 10 air and best pilot campus in india are other country in lowest payment and sure finding jo plz sir

  12. But I’m wondering. What if the engine just overheating and yet to caught fire? How do you tell them apart. And if it’s just overheating does the extinguishing still need to be done or you just give that engine a break. And if you go with the extinguishing procedure will you be able to start that engine back up again?

  13. Question about the "agent 1" and "agent 2" buttons : does that mean that there are 2 "shots" of extinguisher available for each engine? If so, do you dish the 2nd one automaticaly or do you wait to see if the first disch was efficient?

  14. Captain Joe, I have followed your YouTube series for a very long time and seen/reviewed most of your clips. I am a Designated Mechanic Examiner (DME) in the United States and blog on a social media to aid mechanics in studying to take their FAA Airframe and Powerplant rating tests. I use your YouTube clips to show the commercial side and how the systems work to supplement the trainee classroom knowledge. Really appreciate the detailed information as most of it is on the mechanics certification tests. Big pat on the back from us U.S mechanics.

  15. Dear Captain Joe I always find your videos educational also enjoyfull. I want to ask you a difficult ( some aspects diffrent ) question.As you know in history some airliners shootdown with missile ( also some gun fire examples ).Yesterday was annivesary of MH-17 .Whatever for reason sometimes thing like that happens.My question is that.Has Civillian pilot training programs got a education subject like that.Because of conflicts MANPADS are easy to find (and I know it is a big safety concern for many aviation occupiers and experts)Take off and landings are huge risk.Due to their payloads radar guided missile ( like BUK , Aim 120 etc) strike cause seems hopeless but also I wondering can pilot survive this situation (also aircraft) Evasive maneuvers like that.Basic answer is : be pro active and don't fly in combat zone . Some crisis are unexpected.My second question : After this kinds of incidents some experts suggest that manufacturers can put active (chaffs/flares) and passive (radar warning systems-rwr, electro jamming systems etc) countermeasurements.Some says that people in aviation business are keen this idea.İn reality there is not a such plane ( of course I'm not mentioning airforce1).What's your opinion about it.My third question about airplanes structural integrity.After such a strike what kind of damage airplane survive.İn ww2 B-17 can land realy bad situations without rudders , without elevators , without losing some parts of wings and fuselage.I don't believe todays planes worst then B-17.İt's long post but a video such this subject will be good.Thanks a lot.

  16. I wonder, if you get the fire warning, but theres nothing else indicating a fire, would you still press the button?

  17. Are Airbus planes affected by fire horribly due to the fact that a great amount of it is made of carbon fiber or do they have the same amount of strength against fire like other aluminum planes?

  18. This is an excellent video, it takes time to create something like this, just to clarify a little bit, on min. 5:15 the fire extinguishing bottle can not be discharged from the external power panel, there are a fire light and a shutdown switch for the APU in case of fire, we should never use that switch to shutdown the APU in a regular basis because there will be no cooling period for the APU, it will shutdown inmmediatly, which can damage the APU. Besides it, this is an excellent work you have done, you have summarized the entire system in a six minute video, congratulations!!!

  19. Would it be useful to increase altitude to lower the amount of air the fire gets? Or would you need to increase the altitude too much for it to make sense since the engines need air as well?

  20. Good morning Joe can you make a video of some previous video you make like this fire protection program, fuel system and the like. Thank you and Happy New Year

  21. Because of your videos my flight simulator sessions became very interesting. Thanks a lot Joe 😊👍👍👍👍

  22. I wish that’s what the fire alarms were like at my school. You get a quiet but pretty annoying chime and a light illuminates that says fire. We get ear piercing and extremely annoying horns repetitively squawking whilst strobe lights blink around the entire building. I think I’m going to ditch America and live in Germany.

  23. Next: why do planes fly higher than mount Everest (where you'll lose consciousness) and how does it get pressurised?

  24. Captain Joe, you said that if the APU catches fire (WHILE ON GROUND), the Fire Detection Unit (FDU) automatically shuts down the APU and discharges the Fire Extinguisher. What happens if the APU catches fire during a flight and how do Pilots cope with that situation?
    Please try to make a video discussing about a fire catch in the APU during a flight.
