F-35 and Airshows

Long time lurker, but I found this F-35A demo in my YouTube feed and it has some great vapor, as well as a pretty energetic demo.

F-35 skid turn, 13 seconds, 360 deg.

This appears to be a pedal turn filmed from almost directly below the maneuver.

I am thinking about the same, but the radius is much larger than that of a conventional pedal turn.

Perhaps, though I think it is a bit hard to say from this angle, and without knowing more about the circumstances where the filming occurred. Also, it is possible the pilot modulated (?) the control inputs here? The camera zoomed out mid-turn, so the aircraft was likely getting closer (i.e. losing altitude), which is consistent with a pedal turn.

Entry for the pedal turn is an inverted pull back toward the opposite horizon, upright at ~50alpha. Am not sure what kind of airspeed they see at the start of the pedal turn but many appear to overshoot the alpha at very slow airspeed; as a result, we see some lowering of the alpha and addition of forward velocity after the pedal turn begins (as steve suggests).

RAAF F-35 pilot says 'there's no time for fear' as he prepares for Supercars display above Newcastle
11 Mar 2023 Madeline Lewis, Jenny Marchant and...

"Imagine speeding through the sky in a fighter jet and feeling your head become 80 kilograms heavier. That's exactly what Flight Lieutenant Ross Bowman will experience when he pilots an F-35A Lightning II fighter jet above the Newcastle 500 Supercars event on Sunday.

It's incredibly taxing on his body. "The big thing that I feel physically is the g-force, F-35s get up to about 9 gs," he said...

..."I'm planning on appearing from down the Hunter River, I'm going to scoot over Stockton Bridge and the first time people see me hopefully I'll be low level about 60 metres over the harbour," he said. "Then I'll put on a display for about 10 minutes.

"I'll get up to about 5,000 feet, as low as 200 feet. "I'll get as slow as about 100 knots, so that's 200 kilometres an hour, that's pretty slow for a fighter jet, and then I'll get it up to about 1,000km an hour."

Flight Lieutenant Bowman is the RAAF's first display pilot in this type of jet and he spent months getting the right qualifications. He carefully crafts displays, based on manoeuvres he thinks spectators will enjoy and show off what the aircraft can do.

"I'm going to slow it right down to 100 knots and my nose is going to be pointing right up to the sky, so I can't actually see where I'm going," he said. "I'm looking 35 degrees higher than what my actual flight path is, so it looks really slow and then once I'm finished with that I'll light the afterburner, and because the engine's got so much power, I'll just accelerate and start climbing towards the moon."..."

Last sentence:

"Start climbing towards the moon"

I sure hope not.

Think about it.

At that time of day the moon would will be below the horizon.

Things are upside down here in Oz Dununder. IF you saw me now I'd be standing on me 'ead. :shock:

TYPING.... :roll:

Though I think spaz is right for his example. :mrgreen:

To me it seems that the story is 95% journalist, Madeline Lewis and Jenny Marchant, with 5% pilot.
As to moonrise, moonset times and the moon being visible during the day. You didn't use a smile? That's a different thing. Perhaps you have never noticed. I'd suggest google, for your location. I think it will surprise you.

11 March 2023,

Moon rise? ~ 11 pm.

Moon set? ~ 8 am.

Noon-ish airshow performance? Moon below the horizon.

I wouldn't have said what I said if it was not true.

You should have realized that about me by now.

I only point out facts.

You may need to look at it over a longer timeline. To get a moonrise during daylight. I'm not trying to bait you. You know that an eclipse is when the moon passes in front of the sun. the moon is also subject to time zones.

The USAF F-35A demo hasn't changed much in recent years, so the typical way airshows are filmed don't vary much. I found footage of this demo in Louisville that's unique because it's filmed in the city, over water so there is flares, and there's a bridge and other buildings so you really get a sense of how the F-35 maneuvers. There's other POV's of this exact show in YouTube, but I like this one (even though it has some annoying slow-mo effects at certain parts).

This is a high show so the pedal turn and lightning loop are featured.
