I just returned on Friday from trip of about 2500 nm, including visits in Salt Lake City, North Dakota, and Boulder, CO. Plane worked great, engine ran fine – even at density altitude of 16,500 over the Rockies west of Denver. Typical cruise of 165 KTAS, and 9.5 ghp. (I like my 20B rotary). Had good weather all the way.
I learned that the standard Koch chart for runway requirement isn't a bit conservative for my airplane. Taking off from Boulder (4000 ft) with density altitude near 8000 ft and full fuel didn't leave much excess runway.
Crossing the divide around Rollins Pass. I peaked at about 13,800 MSL, but density altitude was 16,400. I was surprised to note that I was still climbing at 160 KTAS and 500 fpm and still had throttle to go. It occurred to me that the regs give O2 requirements based on indicated MSL, when density altitude must be more representative of O2 content. (Of course I wasn't above 12,500 more than a few minutes).
Air Center of Salt Lake at Muni #2 (U42) were very friendly, helpful and accommodating. Spotless hangar where they put my plane with a jet and twin turbo. (the plane was very happy there).
I've been very happy with my twin GRT screens. They have reliable, functional; and the customer service great. The right screen shows the map with terrain when flying relatively low around Boulder area. All that red terrain is higher than I was.
