SLATS... How they work (inside view)

an inside view at how leading edge slats operate and how they are synched and mechanicaly locked together.

[@gerardmoran9560]

Great video. Slats increase lift by allowing a higher AoA before airflow separation occurs. Increasing the wing area is a distant second. The Trident, any other airplanes, had drooped leading edges for slow flight and they didn't change the wing area. These drooped leading edges, like slats, cause more air to flow over the wing delaying airflow separation. I never flew the Airbus, but most transports use hydraulic motors, not electric motors for flap and slap deployment and retraction.

Hello again! I was wondering what the orange things are blowing in the wind?

[@planesimple8514]

Hello Ashley, those are called "streamers" and they are used to flag things that are disconnected or loose, or temporarily installed. Or to draw attention to areas that need attention like corrosion, dents, damages, etc. Basically they are meant to draw attention to something that needs attention. It's a quick way to find things that you need to come back to. They are usually very vivid colors to make them stand out, even in low light, dark corners they stick out like a sore thumb, which is a good thing. You want them to be highly visible. Basically they are an aid to make sure things are not forgotten.

@@planesimple8514 Makes sense! Thanks.

[@planesimple8514]

Any time.

Are the flaps and slats linked or it's two different systems?

[@TheWikazz]

Do the slats work automatically with the flaps, airflow or from the cockpit?

[@planesimple8514]

They work automatically with the flaps. The flaps get deployed from a selector lever in the cockpit.

[@gerardmoran9560]

Most work with the flap setting. A few jets, mostly fighters, deployed them automatically when a specific AoA was reached. There was a business jet that came out in the late '60s (the Sabreliner?) that had weighted slats that extended when the airflow force dropped to a specified level. They were always extended when they were sitting on the ramp. I checked one out one day and chatted with the pilot. He liked the jet and the simple reliability of the slats but said they would shutter back and forth in turbulence when close to the design extend speed.

I'm here because I'm reading Airframe.

Welcome Jason Rasmussen

[@larsulrich3356]

These are automated right?

[@planesimple8514]

Hello larsulrich3356. Yes they are automated. they deploy together with the flaps when the flaps are deployed from the cockpit.

[@luisalas2144]

This is airbus or boing or embraer?

[@planesimple8514]

None of the above... 😂

[@planesimple8514]

Bombardier...!

LALO, bienvenido a Plane Simple! Si! Efectivamente es un Global. Tienes muy buen ojo! Es un honor tener a un experto en esos slats este canal tan pequeño.
