Yesterday, I flew for the first time on an ERJ. My question is: what are those four little triangle things on the bottom of the leading edge of the wing (near the tips)?

Lets see if I spell this right..... 'Vorterlons'. They help direct the airflow over the wing...and if I remember correctly from ERJ FAM School they also aid the performance of the aileron

Funny you should ask. From my understanding of previous threads, they do what EMBQA said...they're acting in lieu of leading-edge slats.

How they work...not exactly sure?

Vortalons, as mentioned above, create a disturbance in the airflow over the aileron to improve the aircraft's handling characteristics while at lower speeds.

They also serve as daggers to the unsuspecting person walking around and under the outboard leading edge. They are painted bright yellow, but I have seen it happen.
