Pilots and Drivers,
The following is from my log book:
September 19, 2010 Sunday.
Wind SE 7-10 mph
Glider: Wills Wing, Sport II, 155 sq’, 2004
Glider airtime 87:46:30.
Only I towed up today at LRU (Las Cruces International Airport) but in attendance was Dave Church (tow driver), Allen Fisher, Robin and daughter, and I forgot the name of the friend along with them.
I saw for the first time the nose over rack that Dave had installed on his launch trailer. Dave says he next will move the nose release up from the trailer bed to the nose over rack. This will allow shorter nose release cords and a redundant safety tie down cord.
Dave towed me up three times. The 1st tow had me up to around 1,000’ agl (5,450’ msl). I went back to mid field and found the one thermal that I towed through low and started to circle up. (30 minute flight).
2.5 miles to the NW of midfield and only climbing at 200’/min I left the thermal at around 7,000’ msl and returned to the run up area on the start of runway 12. (120 degrees, magnetic) or towing to the SE.
The 2nd tow was totally in between thermal cycles and the flight was a sled ride back to the run up area of #12. (10 minute flight.)
The 3rd tow had me lower than the other two releases but because we were only ¾ of the way down the runway, when I was towed into a thermal, I radioed Dave to stop the truck for me to release the towline. After 42 turns I was three miles NW of midfield, 7,000’ msl, when Robin advised me that Dave was tired of towing me up so I’d better hang on to this one.
Off I go.
Ahead of me, down wind, was Blue Mesa at 19.8 miles from LRU. I decided to try an out and back so as not to make retrieve ridiculously long into the night. Plus Dave was chasing me with my car so me being as frugal as I am decided to stay on our side of the mountain and keep the gas consumption to a minimum.
The saving the gas plan worked but coming back against the wind proved to be just too much with the strength of the SE wind. I was only able to struggle back 3.8 miles giving me a total of 22.7 miles on my planned out and back of 39.6 miles. Adding to the weak lift was the fact that It was after 5 pm before I arrived at the Blue Mesa turn point. Maximum sink dashing between clouds was 1,280’/min. (Too much high pressure sinking air.) The average lift was usually around 200’/min. At altitude when I left a thermal at 10,007’ msl I checked my GPS as I stuffed the base tube for the next cloud and saw that my speed over ground was 58.7 mph. (Good tailwind between 8 and 10K’ msl.)
While I was thermaling I could hear Hadley Robinson chasing Lee Boon west down HWY #9. My squelch was set too high to hear Lee but I could hear Hadley on his powerful mobile unit.
This reminds me… I think we will move to 151.955 frequency up here at LRU so as not to interfere with the tow operation down near El Paso. For the tow up we use the USHPA assigned business band frequencies and only use the aircraft radio for announcing our use of the airport runways and taxiways.
My third flight was for an hour and fifty seven minutes. The three flights totaled 2hr and 37 minutes.
