Can anyone tell me what those little rods/pointers situated on the edge of the wings are ? ( Theres at least 8 or more per wing )

I often get a window seat when flying and wonder exactly what they are and what they measure? ( I presume ? )

I apologise if this is a repeated query/post and very basic......I am still learning !!

If you mean the things on the back of the wing like in this photo (attached to the aileron and on the canoes):

They're not sensors, they're static wicks, which dissipate static electricity built up as the plane flies through the air.

Anti-static wicks were first used on airplanes 90 years ago and, on Zeppelins, over 100 years ago.

I'm surprised that anybody doesn't know what they are but I'm glad that you asked.

Static dischargers were developed by the US Navy when electronic communication and navigation equipment was first introduced on aircraft. Air friction on the fuselage causes electro-static buildup. Without the static dischargers this will reach a high voltage before dissipating into the surrounding air, causing 'sparks' that sound like crackling noises on the radios and disrupt navigation signals.
The static dischargers provide a conductor for this static electricity to flow off before a high voltage is built up.
No more sparks... clear communications!  Wink

We can't solve problems by using the same kind of thinking we used when we created them.
