Re: Railroad Thread
To expand a bit on your teeny text I have 2 words: SUBWAY TRAINS. Unlike freight trains, they're already electric. And also unlike freight trains, they spend a very large portion of their operational time accelerating and decelerating (or accelerating toward the rear if you're a physics major). And...

Re: Pontificating on hard landings...
o/~ You must always go around...And in the plane that I flew, if I had to go around for every bounce I would still be on the pattern trying to land.

Re: "Negative, Southwest, the pattern is full"
I don't see why it wouldn't; other cases of descending off-course have been. Still hasn't turned up on AVH though...Conversely, I wonder if this qualifies as an incident? Maybe not?

Re: Not_Delta 191
It’s not missing. It’s right there in the blue section. I re-traced the plots and re-shuffled (including bringing up the wind plots that were in the next page) to have a longitudinal section in red (thrust, long acc, headwind and airspeed) and a vertical section in blue (control column, normal acc,...

Re: An interesting theory
The sudden increase in density altitude doesn't have to directly cause you to drop 100 feet; it just has to cause you to stall, which is quite plausible. (1) if we suppose for the moment that the stack cloud was around 50C, that's a 15/13 increase in absolute temperature and thus (from the ideal gas...

That plot is a lot more readable! Too bad it's missing the normal acceleration trace though, that one matters.

The only possible reason a headset would be preferable to a HUD is that it's cheaper to get and install.

Re: A flyover of a different kind
It was chanting "bank angle" though. (And why was that audible in the cabin?)I don't know if you can inhibit the bank angle alarm, because it didn't sound (which if the alarm was functioning it would have done at 35 degrees of bank).

Re: Caravan Crash Credentials Connundrum
I don't come here anywhere often enough to participate in this kind of argument. What I originally meant to say was that the crash didn't look like the well-known maneuver we often refer to as "SSCDD", but rather like an ordinary or garden-variety roll that for some reason (I guessed inabi...

Re: Not_Delta 191
I do not believe the captain, based on a somatogravic illusion, ordered the first officer to nose over, and that the first officer blindly complied (or complied, because he also felt the somatogravic illusion). I know it’s total, ass-hat, outsider speculation, but I’m thinking that a nose down inpu...

Re: flat spot on tire, or...?
The plane came in from elsewhere an hour or so before, so it hadn't even been sitting overnight.
Shimmy? Maybe... no idea what that would feel like but I would think it would be more side-to-side than up-and-down.
anyway, not going to find out...

I did a while back. The ground air conditioning is abnormally loud, or was on that flight; otherwise not much to report. Did not check the lav, though.

Most planes if you try that you'll float right off the end of the runway...This is not_me, but could have been. I've done exactly that many times.

flat spot on tire, or...?
The other day on a flight out of DEN, towards the end of the takeoff roll significant vibrations developed, at a rate plausibly consistent with wheel speed. I figured we'd blown a tire and half expected to return, but apparently not. A flat spot is sufficient to produce such behavior, I know, but......

Re: Caravan Crash Credentials Connundrum
It is much more complicated than that. For now I will just say that "stalling one wing" almost never happens, and severe degradation of lateral-directional handling qualities (which is more than just "inadequate roll authority" as it also involves adverse yaw, adverse roll, and ...
