droop down wingtips? are they high?
No, worse (technically better for our position). They're either incompetent or have no actual expertise on this topic.

It's ironic coming from you, since many of your comments are more suitable for Reddit. Maybe you should move over to Reddit full time so that the level of discourse here can return to its normal level.

Slats along with root extensions (LERX), cuffs and dogtooth are all types of Leading Edge Extensions, the illustration has issues but they're not wrong to call it a Leading Edge Extension.
Dei hire.
Slats are leading edge extensions. Lets not be misinformed just because the illustration is stupid about the plane's role.
Slats and LERX aren't the same thing although they have similar effects.
Slats when extended increase stall angle by a combination of pressure gradient smoothing at leading edge, and injection of high velocity flow into the boundary layer via the slot.
LERX also increases stall angle but by creating vorticies that inject energy into the boundary layer and delays flow separation.
Dog-Tooth act similarly to LERX just much weaker
Leading edge cuff is like a slat without the slot, it only smooth the pressure gradient
They're technically all leading edge devices and all increase stall angle, but LERX works on different principle than slats.
They all fall under Leading Edge Extensions, even if they work differently. So calling a slat a leading edge extension is not wrong. Its like taking issue with calling an apple a fruit because its not an orange.
This will be my last post on the Leading Edge nomenclature, lest the thread derail dm your replies if you want.

All LERXs are LEXs. But not all LEXs are LERXs.
