PSA CRJ-700 AA midair collision

The aviation NVGs are miles better than the 7s or 10s you see guys running around on the ground with.

I put a 10 on for the first time in years to do drivers training and couldn’t believe how crappy they were. So the aviation goggles are better, but still a long way from perfect.

I don’t have my NVGs down when flying in or near urban areas due to washout and such.

I don't think ADS-B was a factor. Military flies without it frequently. It is open source so anyone could be watching ADS-B. The mode C was still on and that is all we need for full service in a radar environment.

You can actually track Air Force One on ADSB exchange. I did it when Biden was visiting New Orleans a few years ago.

I don’t equate these incidents with this accident.

I thought about her when I made that post, but running off the end of a runway can be a disaster. No need to look any further than the recent crash in South Korea. USAir 5050. Lion Air 538. Many others.

Alaska gets forgotten about because everyone knows those bush planes crash all the time. Even though Pen Air was a full on 121 op at the time. Shoot, I haven’t seen a thread on the missing Bering Caravan yet.

I read about the Caravan earlier today. You're right that Alaska gets forgotten and as far as I know, there hasn't been a 121 op crash there with significant fatalities. I mentioned PenAir because it was 121. If an airliner ends up in the Potomac off a DCA runway, with 1 fatality, I guarantee it would have major news coverage.

Thread 'Bering Air missing'

I’m in ANC about to do a redeye to SEA. Breaking news here :( some people mentioned it, I just looked it up. Sad, hoping for the best. It’s cold as balls out here.

Doesn’t ADS-B provide more accurate information?

Not to a way that would be useful in their scan.

We’ve asked for ADS-B in and a host of other capabilities our current APX-123 transponder can perform (weather radar being a big one).

The problem is because of the proprietary nature of the software it’s 30-35 million every time we perform a system update across an aircraft fleet, and we have multiple fleets of aircraft. Priority for development not withstanding those updates come about every 3-5 years at best and take roughly 18-24 months to complete across the force.

Now we could get tablets and stratus or similar capability, but those aren’t programs of record nor are they approved in all our aircraft through the air worthiness release. That requires units to fund their own buys because the existing Tak tablets in the fleet don’t support it, and now I’ve gotta have another tablet on a crew member to monitor.

No I don’t like the current or suggested bandaid solutions for the DOD and how it participates or the national airspace system at large. I really hope the work going on to evolve past what we currently have a move to an AI assisted dynamic airspace management cloud system takes hold. For abybody wondering this is what the DOD imagines for the future of airspace, and having worked with the programming offices there is absolutely a way to adapt this to civil use.

From the ATC side of things, ADS is only an improvement where radar coverage is limited. I am quite sure the radar coverage in the DC metro is the most complete in the country if not the world.

Which works to the other issue which is saturation of useful information.

That’s where we are looking to use AI and machine learning in air/fires integration, because a person gets tired and misses stuff or doesn’t see it far enough off. There is absolutely not only an application but a need to start pushing more of that into the civilian infrastructure and not just with ATC.

Evolve or die.

I guess I shouldn't be, but I'm really shocked at the condition of the wreckage for a 300' descent into water. Just curious - if this has been deeper water, would it have been survivable for anyone on board? Curious if deeper water from that height would have absorbed some of the energy, or if it wouldn't have mattered.

At 70mph water absorbs energy about the same rate as concrete.

You’re joking right?

Out of control airplane/helicopter hitting water at 300 ft in a near vertical impact, you may as well hit cement.
