The strong climbs on 10/10/11 were all at the Mt Wash primary, but there was lift all along the Mahoosic range, so I cruised all the way to Sugarloaf Mtn (75 miles or there about) essentially level. There was big sink out there too! Towards the end of my flight I got squashed hard in the vicinity of Old Speck because we'd had a frontal passage with dramatically increasing wind speed, longer wavelength. I was slow figuring this out and lost most of a mile of altitude before I had the thought to shift downwind to reacquire the lift. That was one of the spookier/scarier moments I've had in any sort of flying machine.<br /><br />T8T8https://www.blogger.com/profile/13412271192479554593noreply@blogger.comtag:blogger.com,1999:blog-4589030274248022508.post-35675683829883966392018-11-15T18:02:38.047-05:002018-11-15T18:02:38.047-05:00On 10/10/11 we had to drop back to the secondary t...On 10/10/11 we had to drop back to the secondary to climb to 25K plus and I recall the distinct "forward" lean of the zone of best lift in both primary and secondary. This makes sense in light of Fig 7.7. Like RR, I noted essentially vertical streamlines in some places that day -- circling without drift in very strong wave lift.<br /><br />Great article, thanks Tim!<br /><br />EvanT8https://www.blogger.com/profile/13412271192479554593noreply@blogger.comtag:blogger.com,1999:blog-4589030274248022508.post-90721592944638831942018-11-15T17:29:01.220-05:002018-11-15T17:29:01.220-05:00Thanks Tim.

When people flew XC on that day in 2011, did they find wave in other places besides right by Mt. Washington? I looked now at RR and T8 and they only climbed significantly in the Mt. Washington area.<br />Moshehttps://www.blogger.com/profile/02661118835517288164noreply@blogger.comtag:blogger.com,1999:blog-4589030274248022508.post-63268922901697720422018-11-15T14:46:33.672-05:002018-11-15T14:46:33.672-05:00Here is what Rick Roelke said about October 10, 20...Here is what Rick Roelke said about October 10, 2011:<br /><br /> Well, today was Stellar. Not the typical classic wave profile where it was blowing 60kts at altitude, but all the right things came together for a delightful day. First off, Diamond Jim David, topped out at 29,000 ft. and this was on a day where I saw 10kts of wind at 12,000 ft. <br /><br /> <br /><br />It was really like no other wave day that I can remember. In the range from 12- 15k, the wind was so light that you had to circle like you were thermal flying. Very unlike “normal” wave flying. The lift in that region was not really strong, sometimes perhaps 5kts, but then, climb above that and you were back in classic wave conditions, with 9 kts of lift. The strongest lift reported today was 14kts. After some early climbs, many pilots headed of cross country. I expect there will be many interesting flights to be seen on the olc. Not all made it back, with pilots landing at dean, mount Washington regional, and even Springfield VT. <br /><br /> <br /><br />Yours truly pulled off a flight that I have been trying for years, and that is all 3 diamonds in one flight. After telling Rick Sheppe, he pointed out that it was really all the badge legs there are, in one flight. The task was Gorham to Sugarloaf, to Mousalake, to Saddleback, to Gorham. A diamond climb, 500k distance and 300k goal. Took about 6hrs, could have been done faster, but I had plenty of daylight, and that is all I was racing…<br /><br /> <br /><br />I am quite sure this if the first time it has been done in New England, and perhaps the first time east of the Mississippi…<br /><br /> <br /><br />Great Big Fun…Timhttps://www.blogger.com/profile/13930340991144328658noreply@blogger.com
