So here’s a copy of the SOP. This is the last one they put out and still relevant I believe. I personally filled one of the five slots with certified and a second slot with staff/manager since I was a facility manager as well. Certified gives you 1.0 ranking points whereas staff gives you 0.7 and supervisor 0.9. The experience questionnaire is slightly different than it was a few years back. Previously, it asked you to describe airfield layout experience for each facility you worked (ie intersecting, parallel, single runway, helipad, etc). Now it just asks you to select your facility from the drop down so I can only assume it automatically fills the airfield category for you. Ideally they give extra points for fields with both parallels and intersecting but I doubt it. First go around, I did what you did and put supervisor instead of certified because in the military, Tower sup was higher than just being a local qual. Then I found the SOP lol
