@Articuno The big application I can see is airspace situational awareness. If TFRs appear as a big red curtain wall in front of you there's no way you're flying into that accidentally. Also having your airway projected on the screen would be nice as opposed to having to look at the needle (think flying in actual IMC)
@falstro Interestingly MY plane is not placarded against spins. The substantially identical airframe manufactured I think 3 years later IS placarded with Intentional Spins Prohibited. My opinion about spinning a Cherokee should be pretty obvious :-)
my PhD advisor texted me last night a picture of a nice microburst on radar as he was departing MCO. I grabbed the tower ATC feed from that time and these guys were operating with ATC telling everyone "wind shear alert microburst warning, 70 kt loss."
I think I would have waited that one out
and from the sounds of it they were the last, or nearly the last plane to decide to depart ahead of the storm the microburst was embedded in. The plane behind them took a look for themselves and declined to depart
The wind shear scenario (modeled after the fatal at DFW) was the only sim scenario I crashed. And my sim partner crash. Then we crashed it again. Finally the sim instructor stops giving us shit and looks at his console. "oops, i set it at 200% rather than 20% of the DFW shear profile, no wonder you guys kept killing everyone"
I almost "crashed" the performance decreasing wind shear event at my first captain PC. I was in the turn to line up with 19 at DCA (coming off of the Rosslyn LDA). You make that turn short final and at or around 500' AGL, and in the middle of that turn I get the red windshear EICAS alert. Rolled level, wasn't quite over the runway, kept sinking, I was ready for the impact and my FO finally yells "POSITIVE RATE!". Radar altitude 5 ft. :)
brought it back around for a single engine ILS and during the break my sim partner was shaking in his boots at how "hard" my PC was and if he was up to that challenge.
The instructor gave him the IAH profile, which I suppose is "easier". The DCA profile was a lot more fun though
@casey "No wonder you guys kept killing everyone" -- Things you only want to hear in sim training?
there's that scene in From The Earth To The Moon with the sim team that springs to mind: "We have to do everything in our power to ensure that they are ready, which means we must do everything in our power to kill them!"
(Fun Facts: In the Redbird FMX simulator you can't overpower the autopilot -- if Otto decides he wants a 1000FPM descent on short final you can pull the yoke all the way back to your chest and the sim is STILL GOING TO DESCEND AT THE COMMANDED RATE)
Fortunatey the Redbird is dinky enough that it can't kill you. It might maim you a little if you stand inside the motion arc, but it can't really kill you :)
@casey yeah we actually paused the simulation about 50 feet above the runway to figure out what the hell was happening -- something about "full throttle and the yoke in your chest but we're still descending?! What the fuck??"
@casey this would be the equivalent of "Here, hold this wire. What? Would I make you hold it if it were live?!"
There's a better one I can't find online with one train in the station and you see people just running past the gates to make it. The last one gets splattered by an express going in the opposite direction - they pulled that one because it wasn't computer-generated, it was an actual video from the Bethpage crossing
@ratchetfreak We have poles, bells, and flashing red lights - people are STUPID.
I used to work by a 3-track line, we'd have at least one impact a month without fail because the gates would come down a full 3 minutes before the express comes through and people would get tired of waiting
and it's like "Uhhh, really guys - if he hit the emergency stop the second those poles came down the engine is still going through this crossing. They're doing 75-80mph and they don't stop very well!"
@ratchetfreak "These trains go fast. Very fast. You won't see it coming but it will still hit you." at least if we had trains that regularly exceeded 55 mph. (yea, there are a few on the east coast, I know)
The Turn Radius of the SR-71 would depend on its speed. The faster it went the wider its turn radius was.
The SR-71 had a minimum turning radius at altitude of about 80 nautical miles (NM) . It was not an airframe limitation but a matter of wing area. At 80,000ft, the air is too thin and the w...

Does that answer even answer the question?
user35386
I'm trying to find what the minimum turning radius at 3.2 Mach at 80,000 feet is, but I can't tell from that answer.
sorry, is that temporal consistency is one of the first things I check in the thesis of my students: - the airport *was* towered - the airport's runways *are* one line after the other. @Articuno's explanation thus does not hold (the runways as well *were* and *are*) could be related to @voretaq7's point, they may want to underline that at the time the tower was operational
@Federico yeah I think that's what they're getting at - It was a controlled field at the time (tower in operation) as opposed to uncontrolled (off-hours -- which during Oshkosh actually means "NOTAM'd Closed")
It's difficult arranging a week off (because c'mon - if I'm going I'm going for the week!), and at the moment the plane is in pieces (but all the fucking paint is off finally!!!)
the spot landings bit - grrrr. Yes i can manage spot landings, no I'm really not thrilled about doing it with pretty much all of US GA standing there holding rate-a-landing cards :P
(also I hear tell that if you fly in at certain times of day the multicolor dots are actually varying shades of "Freakin' sun glare!" -- just in case it wasn't challenging enough :P)
My landings are generally better after I've had the shit kicked out of me enroute -- so by that logic I should do beautifully at Oshkosh!
I would need to locate my tent (or acquire a new one) -- low-wing aircraft not so much with the "camp under the wing" ("wake up, sit up, and impale yourself on a fuel vent")
I used to get to do more interesting spot landings when I was renting from NFI (they're all the way on the north end of the field, so landing runway 1 I'd ask for a long landing and try to hit a spot)
Now it's more "I don't want to taxi back to the ghetto tiedowns for an hour - put the wheels down near the numbers and make the early turn-off or the intersection!"
(which is nice because when I have to take the cowling to bits to chase out the birds the whole airport isn't watching)
@BretCopeland there was a whole month where I could not catch a break and had some kind of jet chasing me down final every damn time so I would make the turn-off onto B just to clear the runway
(at which point I have to ruin their day by telling them "Uh, going to alpha ramp")
@falstro give or take yeah, I really hang out the laundry on short final because I don't like a long-ass roll out
@BretCopeland The worst is when you can't hit D1 because you had to come down short final at 80 knots to avoid being a Citation's hood ornament - that pretty much condemns you to making the hairpin turn onto alpha. I squeaked tires on that one.
@BretCopeland I go out every week or two to stare at the plane in pieces -- I'm hoping I remember how all those switches and levers and stuff work when it's back together! :P
It's been.... since June 7th
(you'd think I'd have more disposable income but I had to go and buy landing gear legs and gyros. <grumble>)
@falstro <appopleptic sputtering and wild gestures at deflected control surface and stick/yoke> !!!!!
Somewhere on Youtube there was a "sabotaged" cessna for people to preflight and some of the items were "Yeah I can see how someone might miss that on a Day VFR flight" (nav light lenses swapped), but one of the items was the ailerons were rigged backwards
like... uh.... you were told the plane was sabotaged. That's the sort of thing you should look for anyway but how do you not think to check it on a sabotaged plane?
@voretaq7 You'd be surprised how many are unaware that you can actually stand outside the aircraft/squat on the wing and reach in and manipulate the yoke to check the elevator movement
On cessnas with the back window it's easy because you can stomp on the pedals (they're bungees so you can watch the tail move) or you can look while taxiing out
yeah on the pipers it's little steel rods - you're not moving the rudder without moving the nosewheel - and you're definitely not moving it by pushing on the rudder, you'll crease your tail before you turn the wheel :)
I suppose you could stomp on the pedal and scrub the nose tire then look out the door (or hold a mirror out to see the tail from the pilot's side) - easier to just check the rigging by jacking the nose though :)
and at least the way the Cherokee rudders pedals are rigged it's pretty much impossible to fuck that connection up (opposite pedals on opposite sides are connected to the nosewheel - you'd have to saw through the torque tubes to get things turning the wrong way)
@voretaq7 Don't underestimate the stupidity of man. I'm sure someone at one point or another went "hmm, this don't fit no more, I need to saw through this thingy her to make it work, here hold my beer"
@falstro I don't think so, let me find the better picture of the linkage
ah here we go
see the two little fittings left and right of that center piece? The rods connect there - one to the left side and one to the right side. It's just a straight rod with two bushings
