Wave Flights - March 12

Saturday was a warm, cloudless, wave day.  Tim (AT), Tom (2W), Dan (EA), Evan (T8), and Jerry and Larry (i1) flew out of Springfield VT (VSF) with the assistance of Andy L. in the Pawnee.  Evan found the highest climb to 16,000'.

I (Tim) took the first tow around 11 AM followed by Tom.  We found week wave to 8,500'.  I was in the primary and Tom in the secondary.  At 12:40 the wave shut off and sent us scrambling to find lift.  I hung out by ridge soaring the west face of Okemo until the wave lift returned about 20 minutes later.  Tom never fully recovered and landed about an hour later.

I found the Okemo wave to have a very short wavelength.  My climb was only 2.5 nm from the summit and I found lift as close as 1.6 nm (over the base of the ski lifts) from the summit.  Evan and Dan's climbs were about 3.5 nm from the summit.  Once I topped out at 9,000' I headed for Killington.  Thinking the wavelength for the day was short I stayed to the west of Rt 100.  I was rewarded with sink all the way.  At 6,000' I was just about to head back to VSF when I found the Killington wave.  Evan and Dan followed a line further west to Killington and did much better.

Dan topped out at Killington at 12,500' and lead the way to Sugarbush.  Evan stuck around a little longer and got to 16,000'.  Dan, Evan and I found our climbs 4 nm - 4.5 nm from the summit, so it looked like the wavelength was longer than Okemo.

At Sugarbush we all found climbs right over the airport at 5-5.5 nm from the summit to about 15,000'.  We all continued north but Dan was the only one brave enough to hop the I89 gap at Waterbury.  Dan made it up to Mt. Mansfield but could not find the lift and had to land at Morrisville.  Evan and I stuck our tails between our legs and headed for home.

The wind was a bit out of the north and made the return to VSF easy.  From Sugarbush to Killington I gained about 500'.  From Killington to VSF I flew as fast as 120 kts IAS which worked out to 153 kts TAS or 176 mph.  With the quartering tail wind the ground speed hit 216 mph!  Evan and I landed about a half hour after Dan.  We packed everything up quickly and I was off to get Dan.

My new theory about wave in the Green Mountains is that the best lift is at the major ski areas (Okemo, Killington, Sugarbush and Stowe).  The best terrain for skiing (tallest peak, moderate steep slope, bowl shape) is also the best terrain for wave.  As an added bonus 3 of the 4 ski areas have airports near by.

Wave Flight - January 14

Here are some pictures from my January 14th flight out of Springfield:

The highest I got that day was 12,000'.  I tried to go north but clouds over Plymouth VT blocked the way just like my last flight.  Here are the skew-T, satellite images, and HRRR model from that day:

Andy L. was flying his Champ out of Post Mills and reported:

Many wave clouds when I headed to the airport. Ended up climbing to 4k on the ridge between Warren and Stinson Lake, was heading north towards Dean and the lift seemed strong so I headed to the leading edge of the clouds and continued on to 8k. Got my ground speed down to 12.9 mph.

Note the "hole" popping out from cloud deck, I just had to fly through it.
