Here’s the SOP stating how facility levels/types are offered. You have to fit the perfect resume in there pretty much to get the 7, 8, 9 facilities. A bunch of experience has highly complex, intersecting runways, high traffic volume towers should certainly put you in the “high score relative to the pool” category. I have about 7 years worth of CTO experience on 4 towers plus radar final and approach. Will be interested to see how I stack up. If I still get offered 5, 6, 7 I’ll probably seek out another top contract tower to fill my 5th tower slot and if that doesn’t work, I’ll just accept my fate lol
