A-6A versus A-6E Inboard Wing Fence Locations

 1 July 2023: It turns out that there is the same drafting error on two different Grumman drawings with respect to the location of the inboard end of the leading edge slat. I've corrected it.

A question arose about the the location of the inboard end of the wing slat on the A-6A versus the A-6E with the inboard wing leading edge ECM antennas. The answer is that it was not changed. Note however, that the inboard wing fence location did change: it was moved inboard of the inboard pylon.

All dimensions shown are "wing stations" measured from the fuselage centerline.

McDonnell F2H Banshee Canopy Actuation

The F2H Banshee canopy was actuated by a rack and pinion mechanism. The rack was mounted fore and aft on the canopy, attached at its aft end and underneath the cross brace. The pinion was driven by an electric motor mounted on the deck under the canopy. The rack was angled slightly upward going aft so as the pinion turned, the aft end of the canopy moved upward as well as aft. The forward attach points of the canopy were in a track that caused the front end of the canopy to go up as well as aft also for clearance of the pilot's helmet. The -1/2 and -3/4 canopy actuators are very similar if not identical.
