Software Tweak Lets Delta E175s Fly Into Aspen (simpleflying.com)

Delta Air Lines and SkyWest Airlines began flying Embraer E175s into Aspen/Pitkin County Airport after a FADEC software modification added 1% to 3% more takeoff thrust from the GE CF34-8E engines. The update, combined with recalibrated speed schedules, lets the 76-seat jet meet climb gradients at the 7,820-foot airfield with full passenger loads. SkyWest plans to operate 25 of these modified jets by the end of 2026, serving Delta and United routes into high-altitude mountain destinations.
