Yellow Sun,
Thank you for your correction. I never landed the Nimrod ( AEOp at the time) and every landing when I was in the back
(stationed at Kinloss) was in the direction for the wash. We also came in from Malta once and made a 180 on the runway and used the wash.
I was at Woodford for a couple of years but never saw anything that suggested the wash was beneficial when the airframes were cut up/cut into for the MK3 AEW.
