Haha! They look like they’re only partially out to me. Is the Viggen a 3-way switch that has extend-neutral-stow like most other fighters? Could it be that he simply didn’t get them all the way stowed?
The other devil’s advocate part of my mind wondered if having some extra drag on was to help ‘stay in the box’ for the show.
I realize with a hint of embarrassment that I have actually never seen a video of a Viggen flying. It’s not due to a lack of respect. Just a coincidence probably. Watching it fly with such grace while flexing working class muscle, I sense a lot of F-4 mojo.
(I need to get out from under this rock more often.)
You hold the switch backwards to deploy the airbrake to the wanted position, where it will remain if released. Pushing the switch forward retracts the airbrake. If the landinggear is deployed, the airbrake deploys while the switch is held back, and retracts when the switch is released.
I need more drag when turning, said no delta wing pilot, ever…
But seriously, no, I doubt it. The speedbrakes on the Viggen are pretty useless. Like I mentioned earlier, on the JA (Fighter) version, they decided that the airbrakes weren’t needed. Yes, they’re still on the airframe, but they don’t work…
Good point. I’ve only flown aerobatics in a pretty slick airframe where some extra drag might have come in handy at times. Obviously never flown anything with a hot seat or a delta wing.
Might could have saved a few kgs by removing them and fairing over the empty spot, but that would require extra engineering work, and it’s 5:00pm on a Friday so lets just delete the switch and call it good!
