A quick reply re the acceptance of the two take-off strips is:
The strips are a success. However, really as I see it, it is best to suspend
judgement for a year or two. Time will tell. For example, how will they stand
up in the summer heat to ning-nongs turning a glider on the spot prior to
climbing on board for a launch? Main wheels can screw the bitumen up in this
manouvre!
The earth works which created the strips also left significant areas at the
sides disturbed due to drainage shaping of the ground, and this combined with
the stones broomed (vacuum sweeping was reserved for other areas of established
seal subject to resealing - not to be used on new seal) off the strips after
the sealing process means that we have a fair bit of small loose stone besides
the strips and little grass. Bit by bit some of this stone gets back on the
strips such that we will have to broom sweep again from time to time using our
geriatric kit from Departmental days. For example, you need the tuggies to
observe not crossing the strip when taxiing, if they can avoid it, so that the
tug doesn't blow stones back onto the strip.
We also have here a K13 and Zephyrus with nose skids. They have to launch
beside the take-off strip and move onto it late in the ground roll after
elevator authority is gained. At this point this seems to work OK. If we did
not do that we would, in my view, see significant damage. The first time you
establish a bitumen seal it looks solid but really there is not all that much
there!

John,
Now that is REALLY weird ; a video comparison between winch launching and
aerotow! ???? I find it hard to believe that you missed the obligatory
childhood lecture (often repeated through the years), on comparisons: Apples
with apples; oranges with oranges. The aerotow box was a total waste of time,
and a major distraction.
Nice video of the winch launch though, and good footage of the changed
topography of the BM airfield.
Did you do any soaring off this or any other launch on the day?
What is the consensus of the users on the success (or otherwise) of the
recently installed launch strips?
Cheers,
Gary

Hi All,
Thought you might be interested to see this comparison between winch
launching and Aerotow.
Greig Wanless and Roger Druce on Aerotow with Axel Allgaier and myself on
Geelong G/C winch.
A great day for winching on Saturday with about 15 -20 knots of wind
straight down 27 we were consistently getting 2000ft AGL.
