Meanwhile, a lot of 737s don't even have a brake temperature indication... I think most of the time my company doesn't schedule them for less than about a 70 minute turn, so there's always plenty of time. Thanks for the explanation of this! I got the whole Fenix family when they released the 319/321, so the Airbus quirks are new to me. Nice to have a good explanation.
I like his channel. Personally I just try to cover more detailed topics that are normally not discussed. Very niche, I know and I guess this will never be a big channel, but if I manage to teach people something new then thats great
Do the brakes regularly reach 300 degrees Celsius during taxi before takeoff? Seem super hot for stopping maybe a few times from a low speed no? I get that airliners are huge and heavy, I just never imagined those numbers. Interesting video!
They are usually hot from previous landings. We fly to some Greek islands with very short runways. It is not unusual to have a brake temperature of 400C or more after landing.
Is there a regulation that pilots must follow regarding when to turn on the fans while parking, or when they should be turned on? I worked for seven years in ground services at Frankfurt Airport, and during summer or on days with no wind, it would burn badly in the eyes, nose, and lungs when breathing near the wheels or when placing the chocks on them
I don't believe there is a regulation as such, only company procedures. Like I said in the video, my company doesn't allow us to switch it on whilst at the gate for the exact reasons you gave.
Yes. In fact there is an Airbus procedure for it. Also, if the temperature of the retracted gear gets too high you are going to get an ECAM warning and you have to put the gear down. Of course, you first need to make sure you are flying at the correct speeds. It is not a nice procedure as it is very noisy and it is best to inform the passengers to make sure they are not alarmed.
in the end you said "the colder the brakes, the better it works." dont carbon fiber brakes have a higher "optimum temperature range" than steel brakes? i thought that the hotter carbon fiber brakes are the more efficient they get until they hit their peakpoint of said range (~500°C) where they will start to work worse and worse.
You are correct that there is an optimum range. In fact there are two. However, this depends on the manufacturer of the discs. The manufacturer I know states that they work best at very low temperatures ( 0 to 80 degrees). Then there is a range that is not so good for the brakes and causes high wear ( 80 to 250 degrees). Above that wear and tear is better again but only up to 500 degrees. Then the health of your brakes decreased rapidly.
In my company, sadly, we can not get the parking brake off when chocks are on. so sometimes, have to leave brake fan working during turnarounds. Sad for ground staff.
To my knowledge Airbus gives no definite time. Once you switch it on you are limited to 150C until the next landing. Would be interesting to know though.
Hallo, meine Bremsen werden im Fenix immer heiß. Sind immer über 300 Grad. Wie lange dauert es zirka in Wirklichkeit bis die Temperatur auf unter. 200 Grad sinkt, bei einer Außentemperatur bei . 20-25 Grad hat? Im Fenix dauert es eine gefühlte Ewigkeit..... Wie lange bleibt ihr im Durchschnitt am Boden zwischen von der Ankunft bis zum Abflug. Schöne Grüße
@@walterp7097 Unsere Bremsen sind ebenfalls immer sehr heiss. Oft 300Grad wenn wir am gate ankommen. Unsere turn around Zeit ist meist 40min. Danach haben die Bremsen noch etwa 180grad und wir kuehlen sie mit dem fan auf 150 herunter
@@TheScaryBoy01 I have never heard of that. Airports are very busy these days and in the AOI they will tell you at what exit you should leave by the latest. You have to inform them if you can't make the exit. Long rollouts do usually cause longer taxi times and therefore more fuel burn. We have no such paragraph in our SOPs. Most airports want you off the runway asap. There are some exceptions where a long roll out could be beneficial, such as LEJ, but those are very rare.
Can we leave the brake fan on while the gear is retracted?
I forgot to mention this in the video. When you retract the landing gear, the brake fan is automatically switched off.

70 min turn on 737? is it a full service carrier? because airlines like ryanair have a 35 min turnaround.
Little snippets of info like this are great. 👍
Always nice to keep learning, thank you so much for the inside!!
I would have never known without videos like this!
Thank you for the information captain!
The information you give us is invaluable for those of us who want to simulate as real as it gets
This channel is great, it's like the antithesis of A330Driver 😂 he's good too tho

Great video! I’m also highly interested in single engine taxi procedures. (In- and outbound). 🙂
Very good information, thanks. Also, can you do a video with regards to single engine taxi and apu start after landing? ❤
Great topic. Will put it on my list

Thank you. It’s very informative 👍👍
really nice and interesting info, Stefan! Thanks!
Love this series
Quite a bit of new info, thanks.
Do a circling approach tutorial pls.
Good idea. Although I have never done one in real life. 😁
Is it true that after take-off you can leave the gear down for some time to cool the breaks down before retracting?
Yes. In fact there is an Airbus procedure for it. Also, if the temperature of the retracted gear gets too high you are going to get an ECAM warning and you have to put the gear down. Of course, you first need to make sure you are flying at the correct speeds. It is not a nice procedure as it is very noisy and it is best to inform the passengers to make sure they are not alarmed.

@@fsclips thats indeed interessting. thanks for the insight. so i guess it really is better then to keep them as low as possible 👍

How long does it take for the sensor to become reliable again after switching the fans off ?
To my knowledge Airbus gives no definite time.
Once you switch it on you are limited to 150C until the next landing.
Would be interesting to know though.

@fsclips Danke sehr für die Antwort. Übrigens, tolle kleine Videos. Sind sehr informativ. 👍
Aren't some SOP's explicitly say that you should ask for permission for a long rollout if possible?
