737-800 - No Static Sticks?

Thu Apr 08, 2010 3:06 pm

Just flew a Continental 738 this week, and sat aft of the wings. I noticed there were none of those static sticks or whatever you call them, the little metal strips that stick off the back of most aircrafts' winglets, flaps etc. Is there now a better way to defuse static in the new generation aircract?

The number of wicks on 737s varies somewhat. NG's have 2 just inside of the winglet/wingtip. Classics normally have at the very least 2 but I've seen configurations with up to 3 on a wing. It most likely varies depending on the avionics equipment installed and also the number of wicks elsewhere on the plane.

Your plane might not have had them due to an MEL, its ok for planes to have a couple of them broken or missing as they do tend to "burn" and wear off pretty frequently.

Static wicks are a CDL item and the operator can set the number that can be missing based on their experience. Some operator require all be present and some require none be present.

The 738 has 14 "Static Dischargers" installed. A minimum of 12 is required for flight. A minimum of ONE on each wing is permitted; however, if only one is installed, it MUST be located at the outermost trailing edge position.

Called Static Dischargers.
Not possible....The CDL will permit one missing per surface approx.Maybe you were noticing the different area.
