Isaias Wave
Hurricane Isaias blew through Tuesday and left enough wind on Thursday to generate wave behind Mt. Washington, I wanted to try a flight to Mt. Washington. After a late start (2:15) because VW was extracting money from the tow pilot to fix his car, I started thermaling northwards. Thermals were consistent but cloud base was only 5,500-6,000' which is on the low side of my comfort level for a trip to W (Mt. Washington). I took my time and arrived at W around 4:00. Ridge lift was good on the Presidentials and I ridge soared the face contemplating my next move. There were no clouds between the summit of W and the Carters to indicate wave or any other kind of lift. I wasn't sure I wanted to commit to being down wind of and lower than the Presidentials if I couldn't find wave this late in the day. But I came this far... I jumped the ridge into Huntington Ravine. In less about 90 seconds I felt the first indication of lift at 5,900'. A quick 180 to point into the wind and I was in zero sink and then climbing at 1 kt. I was surprised how close the wave was to the summit. 1 kt soon turned into 2 kts then 3 kts by the time I got to 10,000' I was climbing at 8 kts.
Huntington Ravine climbing at 1 kt. |
View of Carters - no wave clouds |
10,000' climbing at 7.8 kts |
After 45 minutes I was just shy of 18,000' and climbing at 1.5 kts. It was almost 5:00 so it was time to head home. I dialed Post Mills into the Oudie and was happy to see that even with a 35 kt headwind I had Post Mills with 6,000' to spare - my kind of final glide!
17,500' - Start of final glide |
After flying carefully to Franconia to make sure the Oudie wasn't lying to me, I finished the final glide into PM at 95-100 kts and still arrived with 4,000' to spare.
It was a great flight in thermal, ridge and wave lift and I made it home for dinner. Thank you Rick for towing and crewing.

No circling needed
I took a swing at a 300 km O&R yesterday, Start/Finish at Dartmouth Skiway, turning at Elephant Mountain, which is up in the Mahoosic range. The advantage of this course is that it runs about as straight along the high ground as you can find in our area. The tricky bit is that you really need to be high at the far end. Berlin airport is a useful bailout, but if you can't keep that in range, the other options are generally east of the high ground, in the coastal plain, and if you have to divert, you have a reasonably high likelihood of getting stuck, then subjecting one of your buds to an O&R of a different sort. IIRC it was about 3:20 each way to Thomas airport in Roxbury (2016 or 2017. Thanks Tim).
It was clear pretty much immediately that this wasn't going to be the day. But I thought I'd take a stab at it and see how it went. I had to hang around until nearly 2pm to let the day heat up to make it even semi feasible.
Here's the first glide
The stats are fun, especially the 108:1 glide ratio (I got some orographic help at Moosilauke and Kinsman).
Here are the stats up to the point I abandoned the attempt due to 6000 foot bases nearing Old Speck. I'd already decided I wasn't going past Old Speck unless I had 6500 minimum... and except in really perfect conditions it's hard to see how I could be fast beyond Old Speck unless I had closer to 7500.
If I took the time to fiddle the settings in SeeYou, that "0.01s" thermal would go away, making it three glides with average distance 42.2 km. The reason for all the left turns is that I habitually start my turns upwind when on a cross wind leg. 67mph was a pretty good speed for Saturday, but it was clear it wasn't going to last. I'll try again some other day. Here's the whole flight.

Breaking up the band
On Monday, Evan (T8) made a great flight out of Franconia, shuttling back and forth between Moosilauke and Berlin, making a couple of wave climbs along the way. It was too windy to fly at Post Mills.
Then yesterday, in winds that were only slightly more reasonable, a couple of big counterclockwise flights out of Post Mills were made by Tim (BU) and Greg (JD)
Finally, today, Dan (EA) and Evan (T8) took off at Sterling and flew west and north for 420 and 352 kilometers, respectively.
We're thinking about getting the band back together.

I guess I'll have to buy the White Album again
The FAA branch responsible for testing has just published an outline of updates and near-term changes in the Knowledge and Practical Tests and associated publications:
We learn from this handy reference that:
- There will be new Knowledge Test questions.
- There is a new way to schedule Knowledge Tests.
- There is a new source of practice tests.
- there are (or soon will be) new versions of
- Pilot's Handbook of Aeronautical Knowledge
- Aviation Instructor Handbook
- Risk Management Handbook
- Airplane Flying Handbook
- There are no more "students." We're all "learners" now.
- There are no more "cockpits." Now the proper term is "flight deck."
- If you ain't got an FTN, you ain't nobody.
PMSC Learners who are about to buy an FAA publication, make sure you get the latest edition!
I bought my first aviation handbook in 1965, and I still have it.
I suppose it's time to get the update.

T8 goes for a thousand
His first leg took him down to Snowy Mountain on the Virginia/West Virginia border, 280 km from home. Then he turned around and flew to Williamsport, Pennsylvania, 360 km. Then back down to the Pennsylvania/Maryland border. He made his final turn at 4:45pm, 145 km from home.
The flight took a little over 7 hours, and you can see from the barogram that he didn't waste too much time in thermals.
According to OLC, this was the second longest flight in the world on May 31, 2020.

August weather
It was indeed the best weather of the week, as Tim predicted. However, it wasn't all that straightforward. And it was hot and humid. There were clouds over the mountains, with a westerly wind aloft. Some of the clouds got out of hand, causing rainshowers and blowoff. The wind down low was from the south, which put us square in the middle of weak valley conditions, with the cloudfields to the east and west, just out of reach.
The trick was to leave town early, and Greg (JD), Tom (2W) and Tim (BU) did just that. They made it to the clouds on the Vermont side and followed them all the way to Island Pond, returning via the clouds on the New Hampshire side. You could not have done any better than that.
Evan (T8) and Rick (LEL) struggled to get away, with Evan making at least three desperate returns to Post Mills before climbing back up. At least he didn't land. Rick needed a relight. They both headed for home when the lightning started.
The day ended early with a ten mile diameter shadow due to blowoff. Luckily everyone saw it coming and we made long smooth glides into the darkness to land by about 1600. Evan managed to stay up the longest of all. After that the sun came back out. Typical.
Keith (BA), Dennis (DC), and David (505) were all trapped at Post Mills by the big shadow. Dennis set a record for circling, and David got his first flight of the season in the 1-26.

Weekend report May 22 - 25
We did a pretty good job of observing our amended COVID operational rules.
Under our new (hopefully temporary) rules, every day is a Slacker Day. This isn't great for our primary students, but it makes it easier for our instructors and towpilots to fly on the weekends. Don't let them tell you that they aren't enjoying this.
Another consequence is that our first weekend of the season was also our first 4-day weekend.
Friday
The conditions were blue with light west winds. The day started with thermals to 5000 feet, rising to 7000 feet by late afternoon. Evan, Tim, Dennis, and Eric flew out of Post Mills, and Rick launched at Franconia. Tim and Evan flew nice round trips to the White Mountains. Eric did that as well, but was a bit more ambitious. He wound up landing at Claremont after rounding his final turnpoint at Springfield. Rick also landed out, conveniently, at Post Mills.
Dennis was the hero of the day, driving down to Claremont to pick up NT, bringing Eric back to Post Mills, then turning around again and driving home (not that far from Claremont). He walked into his house at about midnight - and was back in Post Mills the next morning.
Saturday
Technically, Saturday can be called Assembly Day, since the 2-33 and 1-26 went together, thanks to the efforts of David, Peter, Karl, Andy, Don, and Karl's buddy Dave from Florida. That leaves the Blanik, which suffers from lack of pilots so far this season.
The weather was strange. It wasn't blue, but it might as well have been. High bands of stratus and a few altocu didn't help at all. Thermals were sparse and difficult to center, but with patience, they could be worked up to 6000 feet. The wind was southeasterly, which was disorienting.
All flights were local. Kari probably had the longest flight, with Evan and Peter not far behind. Dennis had a short one, and Rick couldn't even stay up. David flew the 2-33 twice and is back on track to get his license early this year.
Sunday
The day dawned clear, but a thin overcast moved in just before launch time and hung around for the rest of the day. From the appearance of the sky, you wouldn't have thought there was any lift at all.
But this is May. The airmass is so good that it doesn't take all that much sunshine to get things going. Tim (BU), Peter (505), and Greg (JD) all had local flights. Peter's total time in the 1-26 this season is 5 hours already. He got to 4800 feet and was the last to land.
Monday
Nobody flew. But before you deny that this was a 4-day weekend, thank Tim for standing by to be the towpilot all day Monday. The overcast was solid, and the slackers gave up early, as they always do.
There are 12 trailers on the field now (including HK, which just arrived from Florida).
COVID update II
Monday, May 18, 2020
Weekend report May 16 - 17
Evan (T8) reported that it wasn't as good as forecast, but he got to 5500 feet in thermals and wave. Tim (BU) and Dennis (DC) also had shakedown flights.
Our towplane is still hors de combat; Andy has stopped making predictions when it will be back.

COVID update I
PMSC Operational Rules During COVID-19
Annual Meeting
We heard the startup plan for the season, which will involve solo flying only, at least for now. Greg presented the new, non-negotiable, COVID procedures.
There won't be any dual checkrides, and everyone is encouraged to talk with an instructor before the first flight. The towplane isn't quite ready, but it should be back in the air soon. Flying days will be arranged individually, like Slacker days.
We spent some time talking about how there's really no good solution for getting a retrieve. The major takeaway is that we are all responsible for our own retrieves, and that the normal pressure we put on club members to volunteer to be a crew has been removed.
Tim presented the Treasurer's report, which led to a discussion about how to pay for the painting of the towplane, scheduled for the end of the season.
Our July 4th encampment at Franconia is cancelled, with an unlikely chance that it may be revived at the last minute. No commitment one way or the other on Gorham.
It was really good news to hear that all of the current members of the Board of Directors were willing to serve in their positions for another year, and all were re-elected by acclamation. Thanks Greg, Mark, Tim, and Eric!
Thanks also to Eric for being the ZoomMaster. We should meet like this more often.

Teaching new tricks
In these modern times, we teach our students things that, in the old days, our instructors never heard of. It is interesting to me that it isn’t just the pilots who learn from experience – the state of the art of flight instruction has evolved as well. “Best instructional practices” have come a long way since I learned to fly fifty years ago.
A troubling side effect of this evolution is that we old guys sometimes downplay or ignore hazards that have been discovered since we became instructors ourselves. “It wasn’t part of my training, so it can’t be that important.”
A good example of this is towplane upsets. We were taught to verify that the rope was disconnected before turning, but that was about it. My instructors never mentioned anything about suddenly yanking the towplane’s tail upwards, or the factors that might lead to this happening. Consequently, my attitude for many years was a casual “stay in position and nothing will go wrong,” and as a young CFI, I began transferring this attitude to my students.
Then two things happened.
First we started hearing about towplane upsets in the UK. Some of these were fatal for the towpilot. The initial reaction of the British Gliding Association was to place an urgent emphasis on doing a better job of teaching the transition from winch launch to aerotow. Our initial reaction was nothing to be proud of – we dismissed the problem as something that occurs only in foreign lands where primary training is by winch launch.
The second thing that happened is that I became a towpilot. I would like to say that this caused me to lose my casual attitude, but I cannot. I tell myself to think of the release handle every time I advance the throttle for takeoff, but I still fail to do this every time. Old casual attitudes die hard, I guess.
We need to understand that this is much more than a problem of transitioning from winch launch to aerotow. There are many contributing factors: short ropes, light towplanes, CG hooks on the glider, upside down hooks on the towplane, etc. All of us - towpilots and glider pilots – need to be experts on this subject.
Fortunately, the BGA has stayed on the case. Their research on this is the best in the world. Start reading HERE. Follow the links. Watch the video clips.
If, due to my former casual attitude, I forget to emphasize towplane upsets in my conversations with you on the airfield, remind me that it’s important. Thanks.
