Flying Colorado's Dolores River
Dolores River near the city of Dove Creek, CO. Dark brown color on sectionals, indicating high elevations, used to worry us. After all, our Zenith 601HDS has a Rotax 912 engine whose 80 hp output at sea level rapidly declines with altitude. For example, for 14,000 ft altitude at 45 deg F, density altitude is 16,500 ft; Rotax engine output then drops from 80 hp to 30 hp. But maybe flying with minimal luggage and without a passenger, the plane could be coaxed to the higher elevations. This summer, we tested that idea on an extended trip to Colorado. This post is the first of two reporting the results. We fly to Grants, NM, to meet the FBO again, this time consisting of three very friendly and helpful persons: Ray, Lynn, and Rory. Grants always has hangar space available and allows a very early departure: We just open the hangar, pull out the plane to get under a strong ramp light, preflight, and take off, without anybody else in attendance. Shortly after landing at Grants, R...
