There aren't any UAX Q400s in DEN. As someone very familiar with the UAX ASE ops I know what the original poster is asking. The poster knows that United Express CR7 will be having performance problems getting in and out of ASE as the runway is shortened, so he is wondering if Republic's Q400s will have weight issues in and out of ASE. I know that Republic (previously Lynx) can circle, so tailwinds won't be an issue for them on landing. On takeoff, I have only seen them depart Runway 33 as runway 15 requires a waiver for departure. I'm not sure what their tailwind component is for takeoff, but with the runway now being shortened to 6500ft from 7000ft and on some days shortened to 6000ft, I think a tailwind for departure off 33 can give them weight restriction issues as well. It's no secret, (United does not have flights booked on these days) Skywest is not operating in and out of ASE on the days that the runway is 6000ft long.
