Will that “prayer” be added to the pre-flight checklists…?

Hmmmmm…
Clearly BMS has done a good job with fidelity.
Proves your oft’-repeated point.
There is ONE thing, though.
I recently downloaded your “airbrakes” sound from Dropbox.
I am loving the realism/immersion it provides.
HOWEVER… I did not hear that sound at all in the video.Did she not deploy the airbrakes…?

Because she didn’t bought this option.

@Dee-Jay I always wondered how the breathing sound can be heard so loudly in the helmet. I mean, if I push the comms button than it’s obvious that others can hear me breathing. But even the pilot itself can hear that in the helmet so loudly?
If I put on earplugs or a headphone, I can hear my breath louder, but not as much as I can hear in this video. Just wondering about it, having no experience with breathing mask -
beyond the ventilation, you can hear the engine speed variations…I like it

@hiuuz I believe that is recorded from the intercom channel. Short answer, yes, you are going to hear the breathing because the microphone is inside the mask.
Some aircraft intercom is just that, inter communications between the crew and turning down would prevent that from being played through your headphones as loud. Some will also have a squelch setting for this channel and you possibly could squelch out the breathing, but also risk shut out similar level sounds. A fighter oxygen mask is positive demand, so as soon as you diaphragm starts to change the pressure for inhale, it will force oxygen into your lungs. This makes the breathing louder than normal.
Actually one of the things I train my civilian flight students on headset microphone positioning is to make a small enough noises that you can’t hear with the hearing protection on with the microphone is away from your mouth and then move it closer until you hear it. It’s a unique problem to have where you can hear your own voice in your head, but can’t hear it in your headphones, which means you talking to the crew or your voice on transmission will not be heard. Aviation mics are very directional to not pickup the aircraft nosie.
In a single seat fighter, often this is a hot mic channel or sometimes a kind of master volume level. So if you have it turned up, you will hear your own positive pressure mask breathing played through your headphones.

Mainly through the ECS (air cond).

Correct.

In the Soviet two-seater aircraft they do not have a hot microphone, you have to press a switch for communication between cabins and another for the radio. In the case of Soviet transport aircraft, there is a control box (SPU) that has a small switch that allows you to put the intercom on hot but without sensitivity, that is, all the noise and voice are transmitted, we used this a lot for the pre-flight check , inter-flight and post-flight, but later returned to the working position, which was, pressing a button to talk with other crew members, in the case of the Mi-8,17,24,35, the stick has 2 notches the first is the intercom between crews and the second is radio. In the case of the An-24, 26, 30 in the captain’s horn the button on the left is radio and the one on the right is intercom
I remember the first time I breathed oxygen through a mask it was with a KM-36, it has the microphone inside the mask cavity; I remember that I sat in an L-39, I connected the mask to the connector of the chair and I put on the mask and put on 100% oxygen, I remember feeling that tasty smell of fresh air with small hints of medical alcohol and that my lungs filled up completely with the positive pressure of the system, when I breathed I felt the valves of the same mask as they activated when exhaling and inhaling, after I took off the mask and began to breathe normally I felt like a vacuum, like I was short of air.
We also used 100% oxygen when we came to work after drinking, after a whole night without sleep, 10 min in 100% oxygen and ready for war. Of course, later you had to call the oxygen truck to refill.
In the case of the KM-32 and 34 mask, they use a microphone attached to their necks, called a laryngophone, which prevents breathing from being transmitted through the intercom or radio, but the voice quality is not very good.
