AVIATION PING!................
How conveeeeeeeeeenient.
It automatically overwrites periodically.
I doubt there was nothing on it. More likely it operated for more than 2 hours past the event, so the earlier event was over-written. Per US policy.
AI ? LOL
One thing will come of this:
All maintenance personnel will be required to get covid booster shots.
In the old days, the CVR would record to a point and then start over; as I understood it.
I assume today’s systems are digital, but I don’t know if they erase, then begin recording again or what.
The warning light went off three times and they just pushed the “acknowledge” button.
“Yeah, just a false alarm...let’s ignore it. Need to get that sensor adjusted sometime. The next crew can worry about it.”
That same thought process doomed the first Max that crashed.
Yep, there are a few circuit breakers that are routinely pulled when the aircraft is shut down. One is the clicker on the altimeters. It gently bumps the altimeter because it is such a sensitive device that works on air pressure alone and “sticks”. The others are the CVR and FDR. As mentioned, the CVR records as long as the breaker is is. Older aircraft used a continuous magnetic tape to record the cockpit and were generally only good for about 30 minutes until the tape was overwritten. Newer aircraft use a digital model that has a longer record time.
ok so whats the timing of all of this? Panel blows off, plane lands...
Let’s see if we have this straight - The CVR keeps recording with the plane shut down completely???
