27 July 2013 - Two Tasks in One

Visibility: 10 + Miles
Wind: S 5 at the start, NE 10 at finish
Altitudes: 10 K
Time Aloft: 2.5 hours
Max Lift: 8 kt
Temperature: Didn't note
Comment: Glider - SGS 1-35
Tow pilot: Andrew Oullet

               I spent the night of 26 July creating two tasks in the Magellan navigation system; one south to Orchard Peak, back to 41/33 then Avenal; the other north to Darcy, New Coalinga, Hale, then back to Avenal.  I would decide which one to fly at the field.

                I had always wanted to try the Orchard – 41/33 route so I turned on the Magellan and prepared for the tow.  I checked the weather, packed food and water, took another look at the sky and I was ready to go.

                All of this pre-planning was of little help during the first flight when I put the 1-35 in some pretty dead air off tow to the south of town and found myself back in line 24 minutes later!

                Before the next launch I observed good air to the north of the field and heard Morgan Hall in GD calling altitude and climb rates.  I still wanted to go to the south.  Off tow at about 3,000 feet I was able to climb at a good rate.  I had programmed the Magellan to wake up with the Orchard Peak – 41/33 – Avenal task loaded so I headed south.  Morgan had stated that he was headed that way and I could always turn north if there was no lift.  Half way to the first ridge I realized that the unit was taking me in a different direction so I quickly re-set the waypoint and kept heading to Orchard Peak.

                The lift was strong when found and the sink was predictable on either side.  I was able to climb using dolphin and circling techniques.  I kept in touch with GD, noting that he was always 1,000 - 2,000 feet above me and much farther out!  It was a beautiful day; it was easy to stay high and make good time. 

                After rounding Orchard Peak and 41/33, I decided to attach the north task to the day and headed toward Black Mountain, finding lift and seeing small clouds coming and going ahead.  I was able cover some distance before circling in a couple of thermals.  Looking to the north and west it was easy to see the clouds marking the convergence; they went in that direction as far as I could see.

                I kept running north-west until I was near Center Mountain.  At about 7,000 feet I found another thermal and took it to 10,200.  I checked the Magellan and found the battery had given its all; the screen was blank.  Still, 10,200 is 10,200, so I ran straight to New Coalinga, turned right and then straight to Avenal.   

                I arrived with altitude to spare so I practiced flying with gear and flaps until it was time to do it for real.  The flight lasted about 2.5 hours.

               In the end, I was able to enjoy some outstanding soaring conditions and see both landmarks slide under the nose in one flight.  Lesson learned? – practice more with the Magellan on the ground and get a better power source!
