Why do We have to check the Accumulator psi in Green before we turn into the stand?

Hey Saurabh, hope all is well my friend. Well this would be to ensure that you will have hyd pressure to keep the parking brake set. Once the engines are shut down and provided all electric pumps are off the accumulator is the only thing that would be giving you pressure to the parking brakes. Of course you would usually have the wheels chocked at the handstand, but its a good safety check.

Hello Mike. I have a question about the engine mode selector. So I understand why you would use the ignition/start position when you want to start the engines and why it is in the before start checklist. The thing I would like to know is why the engine mode selector is in other checklists (like before takeoff) or in other words why you would want to have continuous ignition for purposes other than starting the engines. As always you are doing a great work.

Heya Tomasz, you bet. Great question. Generally speaking, keeping the ignition on continuous in any given situation is used as a means of guarding against a potential engine flame out if you are anticipating flying through an area of either severe turbulence or heavy rain. Interestingly enough, my Airbus manuals that I have are pretty vague as to specific hard number parameters to adhere to when using continuous ignition. But it is there a tool for us if you are ever concerned about conditions you are either taking off into or flying through. Thanks again for your questions!

If we are doing one engine taxi (engine 1 on) and yellow electric pump is off, how does the parking brake get pressurized if we have to stop for any reason?

A good question Saurabh. In this circumstance the yellow system would still be getting pressurized through the operation of the PTU.

Hi Mike. A couple of days ago I started watching this "What do all those buttons do?" series. So far I got to the ventilation panel video and I have a question. You talked about smoke in the avionics compartment but what happens when there is fire down there. Is there a way to extinguish it or the computers and all this stuff down there are just going to get destroyed by the fire? Btw you're doing a great job with these videos. Keep them going.

Hi there Tomasz, thanks so much for tuning into the channel. Yes this is a very good observation you have made and a good question. There is no "extinguishing" capability available in the avionics compartment as there is in the cargo compartment for example, where you can actually discharge halon into this area to put out a flames. In the avionics compartment they have designed it so that you have the ability to quickly cut electrical power to these components and you close off the air flow to this area so you starve any fire of oxygen that may be smoldering.

Hey thanks so much for that Tomasz! I'm always looking for feedback too. Is there anything else you'd be interested to see discussed on the channel here? Or other suggestions on how I could improve upon what I am doing? Cheers! Mike

@@MikeAbignale in one of your videos you mentioned that someone suggested to use a flight simulator to better illustrate what you are talking about in your videos. I think that this is a great idea which would help to understand certain things even better. Other than that I don't have any more suggestions however if I think of something I'll definitely let you know.

Greetings Mike! Had a couple of questions for you. 1. You mentioned that when there is a lose of normal braking, you’d obviously want to activate the alternate braking. How would you do that so as to get the 1000psi limited brake pressure upon landing? 2. Since the parking brake runs on the Y system, do you have to switch on the Y hydraulic pump ( I would assume the electric one) in order to pressurize the system prior to push back and engine start?

Hello again my friend. Thanks again for tuning in. 1. This is accomplished by using the toe brakes on the rudder pedals and monitoring the triple indicator to ensure you are staying at or below 1000PSI. 2. A great observation. During this period of time where no Y pump is physically running, you get pressure to the system through the hydraulic accumulator. This accumulator is an interesting piece, think of it kind of like a spring loaded mechanism that stores up force for usage when the pumps are off. The accumulator actually maintains pressure for a substantial amount of time, several hours at least. So even if the plane has been sitting at the gate for a long time there will still be some pressure in the system without having to use the Y ELEC pump to "re charge" the pressure prior to push and start. It is interesting, I have tried to look this up, but I still haven't been able to find any reference in the manuals as to what amount of time thet claim that the accumulator can maintain it's pressure. I assume it varies with atmospheric conditions though. Hope that all makes sense..

Mike Abignale Hey Mike Great video as always ... According to my FCOM under Landing gear- brakes and anti skid says “ The accumulator maintains the parking pressure for at least 12 h.”
