I have a question for all you pilots out there. I was trying to take off from the airstrip in Evergreen, CO elevation of about 8,400 ft. I was in the cessna 172, and i found it very difficult to take off. I barely made it off the ground at the end of the runway and then climbing was near impossible. I know that these smaller planes can fly in the mountains, but is there something I need to do at higher elevations in order to get more power? Thanks everyone for any help.
