What is demonstrably increasing is CAT, due to climate change. But considering how infrequent these incidents are we might not see a clear increase for several decades.
I’m also surprised that these airplanes have on demand satellite TV streaming to these airplanes but airlines claim that it costs 100k to add that to existing planes. There’s just no way it’s 100k per plane - there must be a cheap way to retrofit the data without having it be reliable since it’s opportunistic. And heck, France is doing it every 4 minutes for their planes so why can’t Americans figure out how to do it.
Also I’ve flown a bunch and I’ve rarely seen the Internet link go out except where there’s technical limitations like crossing the ocean where they can’t maintain an internet and have to rely on preprogrammed content. Given how much money they make from cabin internet, the airlines are clearly incentivized to apply pressure to keep those things running. I doubt I’ve seen anyone be really annoyed when there’s technical difficulties. Most people who fall into that category would have made other arrangements for entertainment anyway.
No, accelerometer data is only recorded to the FDR. Which has a limited storage window (1-24 hours depending on the aircraft) and is slow to download requiring moderately specialized equipment and a technician to carry out the task. Aircraft downtime and technician hours are both expensive and in short supply.

Everything on airplanes is expensive. Even cabin amenities. You have to prove it won't start a fire, was installed correctly, won't interfere with other equipment, won't interfere with the aircrafts structure, and again requires technician hours and aircraft downtime.
Apple and Google could fix this my streaming accelerometer data to the ground when people are connected to in-flight wifi. It is fairly easy to identify which phones out of a set are the stationary ones.
Sounds like you're upset at Boeing and figured you would tell us you're upset on an unrelated thread. Note that it doesn't really matter if you are right to be upset at Boeing or not. It's still unrelated.
At some point the cost of trying to lie and cut corners becomes worse than the cost of compliance and the airlines and airplane companies will just become good at doing a good job here.
> You should ask instead why it is so expensive.
That is literally my question. I’m highlighting that 100k seems really high to make a system that opportunistically transmits data we are already capturing locally. Rather than a flippant “airplanes should be expensive”, why not ask what is the cheapest retrofit we can do that doesn’t change the safety profile. As I said, this system should not be in the critical path and shouldn’t be a required other than the airplanes should generally be maintaining it to be functional (i.e. the SLA can be 75-90% and still provide tremendous value instead of the 100% SLA target for flight critical components which is what that 100k price tag sounds like).
That this is something highlighted by crash investigators as something that would help in corner cases like incidents over the ocean is just gravy.
Also there's likely 200 accelerometers on board already. Onboard wifi is becoming ubiquitous. Perhaps an app that trades in wifi time for accelerometer time would be good trade-off. And wouldn't require tons of certification.
Edit: Turns out this already includes turbulence data, and this is streamed real-time! https://community.wmo.int/en/activity-areas/aircraft-based-o...

What are they doing exactly? Are you referring to the article?
However that data belongs to each airline.
But anyway, where are you seeing a claim that it costs $100k to record and save turbulence sensor data? I don't see anyone upthread claiming that, and the article doesn't touch on it at all.
