Managed to get a photo of a British Airways 747 at KAUS a couple days ago. It's on film so will post once I process that roll. The Runway 35R approach gave it a very nice photo op at the official viewing area.

@DeltaLima what's the mystery about their dotted line?

it's in a different class, but KGSO has a similar one. I always thought it was because of hills on either side of their departure/approach

so they extend the controlled airspace out through the area (that's somewhat an assumption on my part, but I know that the topography appears to be a factor.)

Is there a word for a maneuver intended to simply temporarily attain as low an airspeed as possible—ideally zero, but in any case, less than the aircraft's stall speed?

Looks like a hammerhead turn is a type of this; the airspeed at the top of a hammerhead turn is close to zero.

But even in non-aerobatic aircraft, you can climb at a sharp angle in order to drop your speed below the stall speed.

@TannerSwett The standard way of training stalls is to idle throttle in level flight then pitch up progressively to maintain height as airspeed decreases. That can drop your speed below the stall speed but it won't reach zero (nor is it intended to). I don't know of a name for that specficially other than "stall training", nor a general name for that kind of airspeed-decrease

Right.

The reason I bring it up was because I saw that one question on the main site that's more or less: "How do I launch a drone with a Vne of 80 knots from an airplane with a stall speed of 120 knots?"

And one of my thoughts was: well, it has a stall speed of 120 knots, that doesn't mean you can't achieve 80 knots for a little while.

(You might even be able to maintain level flight at 80 knots, depending on how powerful the engines are... but that's, uh, not exactly the first thing a CFI teaches you how to do.)

@gparyani looking forward to it, is it one of the special liveries? last time I plane spotted using film and then scanned the negatives was 15 years ago, glad to hear film is still alive :) still have that Olympus SLR, probably the shutter is stuck by now

I'd be more worried about what's happening to the drone while it's mounted to your airplane in 120 knots of airflow that it wasn't expecting

@DanHulme I guess the idea is to use a airdropping plane with a tail ramp.

that could be fun while you're nose-up and stalled

:-)

@AJHenderson the mistery is that KACV has a dashed line between their class E surrounding the airport and their class E extension. Normally the extension is drawn as part of the class E belonging to the airport; without any dashes to separate them.

@DeltaLima ah, I missed that

So I wonder if there's anything new about the British Airways flight that mistakenly went to Scotland instead of Germany.

@ymb1 Nope, not a heritage livery, but it is the Oneworld livery

so, for the curious, getting an airspace authorization in conjunction with a daylight waiver for part 107 is trivial. It was like 3 days, and mostly just took that long because they had to wait until the original waiver actually got in to their system
