Dan, I have some memory of writing up my big trip out west but I haven't been able to find it for a long time, maybe years. Probably, I wrote it as a message that I posted on the forum long ago. Since I have posted so much on the forum, it'd be very difficult to sift through all of them to find that message.
I AM NOT AN EXPERT at mountain flying. I only made one big trip in my Coupe from Iowa to Minden, NV, then to Pacific southwest of Portland, OR, then to Coeur d'Alene, Idaho, then to Glacier National Park, MT, then back to Iowa. Before going, I swallowed Sparky Imeson's mountain flying book and tried to follow all his good advice. My own policy was to have an airport under me at all times in any mountainous or high desert terrain. Mostly I used Interstate highways for that but some primary highways were pressed into service. I followed I-80 westbound. As I had the 7146 extreme climb prop (which just barely gives a C-85 Coupe tolerable climb) and was solo at about 1320 pounds, I was virtually always able to get to 12,500'. Flying under PP rules back then and that being before transponders were required above 10,000' I went over the mountains at 12,500 westbound. Taking off from Rawlins, Wyoming, at 10:30 was a mistake as the thermals were up to full power. Here's my rule for the high desert: fly from just before dawn till about 10:30. Then land, check into my motel and fly another five hours the next morning. (Arranging to get from the motel to the airport at 5:00 a.m. is the hard thing.) The thermals get going around 10:30 and it was so rough I had to limit my airspeed to 75 so the thermals were just soft wallowing rollers that would not rip my wings off. Leaving Rawlins at 10:30, just after I got off the ground, at about 100-150', a downdraft hit and I couldn't climb at all. There were no obstructions around so I looked for a clear path to a hot looking spot. East of the airport, back then (in about 1989) was clear space to hot ground a few miles east. I knew the downdraft couldn't shove me through the ground so I kept my airspeed up, stayed level and headed for the expected thermal. That thermal took me easily to about 8,500' and I shouldn't have left it because it then took me an hour or more to get the rest of the way to 10,500'. Later, updrafts helped me get to 12,500' and it was hard staying below that level as I was caught under a cloud street. Just northeast of Salt Lake City, I-80 goes through a tolerable pass. But I, following Sparky Imeson's advice, crossed the range at 12,500' passing over the ridge line EARLY in the morning's smooth air, passing over the ridge line at a 45° angle. The mountains there are, if I remember correctly, about 9,000'-9,500' or thereabouts. I was well over the recommended 2,000' separation from the peaks. In addition, I made sure the wind over the range was not high so there were no problematic mechanical up and down drafts. It was smooth as glass for me. On the trip home, going east from Washington, I followed I-90 from Coeur d'Alene into Montana. Near Donlan, I followed highway 135 through the short mountain range into the Flathead valley then on to Kalispell. After a few days driving Glacier National Park in a Rent-A-Wreck, I took on the next mountain range. Highway 2 goes through Marias Pass at a wide place in the road called Summit. This is the lowest pass in the northern Rockies at about 5280'. Since I knew the road and valley climbed steadily from West Glacier to Summit, I started off at the altitude I wanted to have going through the pass - about 7,500'. I chose the low altitude so I'd be sort of "in" the mountains to get that mountain flying experience. to enjoy the park and scenery. The highest airport on this northern route is lower than 5,000' as I recall. On the I-80 route, you'll have one or two airports at 6,500-6,700'. High altitude airports are long so, with my climb prop I never used more than 1/3rd of the runway, perhaps no more than 1/4 of the runway. On the I-80 route, you are over the high desert. The thermals DO go up and down at 1,000 fpm - 1,200 fpm. As no Coupe has ever climbed at 1,200 fpm, you may need to watch for updraft thermals and spiral up in one of them. When you are 3,500' over the peaks, even mountain scenery isn't so impressive. After exiting the mountains on the east side, I flew along the park border up to near the Canadian border, then followed a straight line back to home base which was then in Iowa City. Find out about the prop on the plane you'll be flying and make sure it'll climb. Know what your ceiling will be in that plane. It may take an hour or hour and a half to get up there in a Coupe, but that 2,000' plus separation over the mountain peaks is golden. Don't fly in the mountains if the winds are strong. NEVER, NEVER, NEVER fly UP a valley. Start high and fly DOWN the valley. Airplanes cannot climb as fast as can valleys. Note that when I was flying from low altitude Kalispell to Marias Pass, I was up and level at my safe, over-the-pass altitude before I entered the mountains at all! If the Coupe you are flying has the ability to climb to high altitude, (i.e. a good climb prop), I think you might, possibly, be able to make the trip with good safety. If the bird won't climb, borrow a prop and ship it home after getting to home on the Great Plains. I AM NOT AN EXPERT. Do good research! All the best and keep us posted with a travelogue.
