Buzzing in the Wave
by Michael Newman
Twenty years from now how will I answer my son when he asks "Dad
what did you do when I wasn't there?" I hope someday he must explain
to his son as rewarding an addiction as mine.
We opened Sugarbush in force a week early. The forecast was for rain
but my personal logistics required me to move YG to Vermont a week
before opening. Tony "TL" Lauck,
Bob "90" Fletcher, Robert "8U" Messner and
others showed as well. My excuse was that I had to drop off the
glider so I could pick up my son Brett by air on opening weekend. I
don't know theirs.
Sunday dawned with lots of wind and a much
better than forecast look to it, wave for certain. Us die-hards hit
the field early. The airport wind sock stood straight out pointing
north. The Gazebo sock did the same but, pointing south.
If Mindy thinks its rough, I really WANT to wait.
While we assembled gliders we saw Mindy "You Call, We Haul"
Woodruff take a couple of hops in the towplane. Soon he came back and
allowed as to how it was pretty rough and it might be a good idea to
wait for an hour or so. He then took off for hanger chores. Bob
Fletcher's comment: "Boy, if Mindy thinks its rough, I really WANT to
wait."
The hour was well spent. The wind died down enough to be
safe and I got jostled into being the first off. No problem, just an
ordinary rotor tow to the parking lot. I only hit my head twice. Off
tow a touch lower than I should, I promptly lost the wave. Fighting
to stay aloft in rotor thermals, I worked my way from the parking lot
out the northern spur to the route 100 valley. After about 20
minutes of tough work I got high enough in the rotor to contact the
wave. For those who havent tried it, rotor means simply that the
thermals run around faster than you can. You spend all your time
chasing them and keep bumping into them but never quite catch one.
Wave lift is fun. Its smooth and still. You sit going up faster
than an express elevator and feeling absolutely motionless.
Wave lift is fun. Its smooth and still. You sit going up faster
than an express elevator and feeling absolutely motionless. On this
flight I passed through 14,000 feet and put my oxygen on. Then I
called Boston Center (on 134.7) and told them I was heading for more
than 18,000. When I got to 16,000 they opened the Sugarbush wave
window to 19,000. I got clearance for more altitude whenever I needed
it.
I talked to Doug "DJ" Jacobs who was doing some serious cross-
country from Sterling. Good lift down there. I could hear Tim Wells
at Elmira but got no answers to my radio calls.
At 20,000 feet and
-14 degrees F my wings started to buzz. I contemplated the issues of
how to make a jump from my altitude without freezing to death on the
way down. Terminal velocity about 100 miles an hour almost three
miles up -- that's about a minute and a half to fall before opening,
a long slow count to 180. When I got that far would I still be warm
enough and alert enough to pull the ripcord? Or is it better to just
give it a 20 count and then freeze on the way down for close to 10
minutes, hoping medical science can cure whatever frostbite
occurs?
Well the smart thing to do with something you don't
understand is nothing. Just fly the plane carefully and try to puzzle
it out. Slower speeds stopped the buzzing, faster made it worse. The
glider felt funny, but it flew OK. It was some 10 minutes later when
I could finally see what was going on. Tape sealing between the
flaps and the wing had lifted up. It finally came up enough for me to
see it vibrate in the wind. I watched as a piece tore back and flew
off. The buzzing got better. Just a flap seal that couldn't take
the cold.
For the next 15 minutes I just wished that the rest of
it would hurry up and fall off to restore the normal quiet. I lost
all 15 meters of sealing tape by the end of the flight.
To get
high in wave lift you must play with it. Playing with the wave is
moving from one place to another looking for better lift. I played,
enjoying the perspective. The wind holds you still against the
ground. Moving in the wave is done by speeding up to move forward
(upwind) or slowing down to move back. Turning at an angle and
speeding up moves you along the axis of the wave (crosswind).
Mountains got small and became almost invisible...
Your motions are slow, 5 mph is a lot. Usually the best lift is
above the Sugarbush parking lot. Sunday it was further north, halfway
between Mad River ski area and Camel's hump.
As I ascended the
world expanded beneath me. Mountains got small and became almost
invisible below a blanket of white. The edges of my world extended
downward like an upside down plate.
The air was smooth and quiet.
Time passed unnoticed. The very bigness of the sky, like the "Big Sky
Country" of the western plains filled me with the special peace of
the wave.
Patience is also important to getting high. Below 20
thousand feet I had gone up fast. Now at the fringe of the lift, up
was feet per minute, and small numbers of feet at that. I moved left
and right, forward and back seeking that little extra lift that would
give me a few extra feet. From 20 thousand feet to 23,000 feet took
more than an hour. I played some more but the top was 23,000 feet, no
more.
I should also tell about going to Morrisville and Killington
on the way down. From the exalted height of 4 miles up, my gliding
range is a whopping 160 miles, much further than my cold feet would
allow. Besides Morrisville is north along the wave and Killington is
south along the wave. At 120 knots I was hard pressed to lose
altitude along the way. The whole trip took less than an hour.
With a crosswind of 30 knots and a Baron parked midfield, landing
proved to be the big problem of the day.
Wave flying is a new and, in spite of its peace and beauty,
somewhat dangerous animal. Last Sunday there were two dangers to
watch. First the possibility of the window closing and trapping you
above a solid deck of cloud. This would not be a big problem on this
day. Second, the landing. With a crosswind of 30 knots and a Baron
parked midfield, landing proved to be the big problem of the day.
Airspeed on final was 80 knots, a number which sounds high, but was
just right this day. Gusts caused me to bounce twice and I turned
out onto the grass for clearance behind the Baron and a heading more
into wind. I was thankful that this difficult chore was completed.
Of course, I landed half an hour too soon. After I was the guinea pig
the others waited until I got the glider off and out of the way.
They listened to my advice and found that when the wind died down a
bit, things were much easier. I've made worse landings, I think...
