737-800 Wing Things(!??)
Hi All
A quick (and silly) question. When flying on Ryanair 737-800 recently, I noticed a number of small projections on the upper surface of the wing, behind the slats area. They are about 2inches high, and are aligned in the direction of the airflow, which makes me suspect that they may be vortex generators or something like that. Any one able to confirm this?
Thanks...
