Will,

It just shows the number of messages being bounced around the psx network. Just a counter we had to debug network traffic storms but it counting up 10 a second is fine, 100 wouldn't be.

Sounds good to me

Hello PSX.NET team,

I have a quick question about PSX.NET and the "PSX Messages" counter. Is it something I need to pay attention to? It counts up at about 9 or 10 messages per second, currently at 13,000 and still going up.

This makes me think there's an ever-growing log file on my computer somewhere, as well as some kind of error that's generating the messages, but I can find neither.

What does the counter mean, and do I need to do anything about it?

Thanks!

Back in 2012 I was aboard the late N194UA and that one also had a handheld mike with DTMF keys. United used it to beep their way into the automated maintenance/dispatch phone system using SATCOM phone calls, if I remember well.

I hear at least one or two will be flown out of VABB - not sure what will happen to the other 2...

end of an era...

Sometimes I get it as well.

Last time when taking from VHHH (07R) and KBOS (RWY09). But as I am not using pure vanilla PSX (connection with MSFS), I thought that this was related to my setup.

Cheers,

One good source of information is from NTSB accident investigations, because they always go into detail about the sources of the data they use for analysis. This is from a recent 747-400 accident:

"The CVR records audio in a digital format, and is active whenever electrical power is available. The CVR memory will retain the audio from the most recent 2 hours of CVR operation, which may or may not be continuous. The recorded audio data is separated by the Honeywell download software into 2 sets of audio files: a) a 2-channel recording containing the last 2 hours of audio, and b) a 4-channel recording containing the last 30 minutes of audio. The 2-hour portion contains one channel of audio information from the cockpit area microphone (CAM) and the other channel contains a mixture of three audio sources: the Captain's audio panel, the First Officer's audio panel, and the spare channel which may be used to capture a third pilot station or observer station and/or the Public Address system. The 30-minute portion of the recording contains 4 channels of audio data, one channel for each of these 4 sources... On this recording, the spare channel captured the same audio as the First Officer's audio panel channel."

Here's a photo of the jack which can be used to monitor the pilots conversations (if you were really bored waiting for the pushback request)




... although I don't understand the "Freighter use only" label.

Quote from: Jeroen Hoppenbrouwers on Thu, 18 Apr 2024 13:49As far as I know, only the cockpit area channel is recording audio permanently.

The headset boom mics are permanently live for CVR usage. I don't know if that was an FAA, etc, requirement. The jack panels had to be modified for this to happen.

Some aircraft even had an additional external headset jack for monitoring cockpit conversations in case of hijacking, before the new cockpit door security regulations came into effect. Pretty redundant now. The Classic 747's even had a secret headset jack in one of the main gear wells if I remember correctly to monitor cockpit conversations.

The spare microphone may be referring to a handheld microphone. Qantas fitted at least one handheld mic with a special pushbutton tone generator. I recall this was for HF (or VHF?) usage and the tones enabled the control of directional ground station antennas (for better transmission/reception)

I saw it once before, but I also assumed it was user error... The second time I saw it was yesterday.
