Ms. Nina logs some turbojet time as co-pilot in a Cirrus SF50-G2 Vision Jet on a flight out west. Not only does she fly out to Colorado and Utah, but she also makes several difficult landings at well-known airports like Aspen (ASE) and Leadville (LXV). She shoots the LDA-E approach with the circle-to-land maneuver at ASE and also lands and takes off at the highest airport in North America (LXV) with a density altitude of 12,054 feet.
