Godholio posted:It's almost immediate. Takes a couple of seconds to figure out where the gently caress you are. It's just a few seconds for most people, but one time a few seconds felt like an eternity when I put a guy to sleep in the front seat in an Extra 300. His helmet came up and started moving around in about the normal amount of time, but he wouldn't talk to me. After maybe half a minute of trying to get him to talk back to me and getting more and more worried that some part of his brain got permanently tweaked (beyond the normal GLOC), I got an idea. Idle power and a pull up to near stall made things quiet enough that yelling at the top of my lungs could get through without the intercom. I asked for a thumbs up which he immediately gave me, then it was just talking him through finding the headset jack and plugging his cord back in, which he had knocked out as he slumped over. Oops!

So, airliner chat for a minute please. I'm going LAX->Beijing->Bangkok and back in a few months via Air China. Am I doomed to Saudi poo poo show status or are they an okay airline that will make me feel as nice as BA or at least United?

Yeah that's a pretty hot looking little plane they built there.

Apparently the reason why Saab is in on this project is that the Swedish Air Force desperately needs a more appropriate lead-in trainer to the Gripen NG than the ancient Saab SK.60. Also, I have been told from on high that the Auto-GCAS video In posted earlier was actually the fourth activation of the system, jus the first they released video from.

Based on my extensive sperg sim F-16 experience - none of them were automatic except for the terrain following radar that has a tendency to crash you or your wingman into the ground. I suspect the crashing due to lag spikes part is not in the real F-16.

All of the GCAS systems I've worked on aren't really coupled to the flight controls outside of a stick-shaker or similar. The fact that this is fully autonomous and coupled, and knows enough to put you back into a level climb is boss as gently caress.

People are already questioning why we're about to replace the Gripen C fleet when the average airframe age is seven (7) years, and one of the reasons is that Saab needs projects to keep themselves busy with if they're going to maintain that institutional knowledge they've built up over the last seventy years. Also, having an aircraft manufacturing plant that isn't actually manufacturing aircraft is very expensive and deliveries have already been artificially slowed down as much as they can be.

I often see these afterburner shots and they have these non-continuous, ghosted flame effects. What's the science here? Are these waves, moving backwards? Are they steady in relation to the aircraft?

I don’t know that I’ve ever seen a really good video of them in flight. They’re static on the test stand, and presumably in cruise, but I couldn’t say how much they move under throttle and manœuvres.

Oh BTW, asked my dad (who was in Air Traffic control and working during 9/11) about clearing the skies on 9/11. He said that ATC had a contingency plan for clearing the skies (it does sound like a 'in case of war" plan) and they used that. Apparently Gander had parking space for up to 56 airliners.

The pattern of shocks is created by the under-expanded jet leaving the nozzle, and should be pretty well fixed by the geometry of the nozzle itself (which should change with throttle position to optimize thrust and maintain close to the same pattern). They'll "bend" a little if the plane is executing a high-G maneuver, but that flow is like mach 12 so it's going to adjust much more rapidly than the plane. This is only based on my admittedly limited understanding of compressible flow physics. Someone should definitely do some night shots of fast jets on full afterburner doing high-G turns to confirm.

What I don't understand is that this particular aircraft was inverted, so the radar altimeter was blank when it was diving towards the ground. The altitude on the right scale is above sea level, I assume, which is why these two readouts are so different. So the system would automatically calculate the terrain height, even when it looses a ground reference? If so, THAT'S FANCY!

If it knows your MSL and geographic position, and has a terrain database to compare against, that's all the info needed. Just like civilian EGPWS.

Yup, it was called SCATANA (Security Control of Air Traffic and Air Navigation Aids) back in those days; now it's known as ESCAT (Emergency Security Control of Air Traffic), and is a far more flexible plan to implement. SCATANA was a national plan intended to be applied in the event of WWIII kicking off and needing to land a pile of civilian airliners

speaking of afterburners, this is some of the best footage of the business end of one I've ever seen: https://www.youtube.com/watch?v=fBE41A9VT3Q&t=65s (and a lot of photo nerds probably agree with me judging by the sound of all the camera shutters going off when it lights up)

Just thought I'd share this gem from Hacker News, talking about the F16 automated recovery:quote:"What would be really useful would be a way for controllers on the ground (not ATCs) or in chase planes to assume control of airliners performing erratically, not responding to calls from ATC, air defense fighters, or their corporate offices. THAT could have averted the Germanwings crash and the 9/11 collisions without the need for highly classified hardware in every airliner."

I would not be surprised to learn that Boeing and Airbus were already working on something similar to integrate into an autopilot. I guess that wouldn't prevent a pilot-guided 9/11 though.
