Low tow has some advantages and is the GFA preferred way, but is
certainly not mandatory.
From the BGK:
"When the tug leaves the ground, a noticeable slipstream is
produced from its wingtips and this
combines with the propwash to produce considerable turbulence. If
intending to carry out a high tow,
a position above the slipstream is maintained as the combination climbs
away. Remember that high
tow is, by definition, just above the slipstream, not above
the tug. The slipstream is the primary
reference, not one of the fixtures on the tug.
Note: Slipstream is composed mainly of wingtip vortices. It
is only present in flight, not on the
ground. The only tug-produced turbulence on the ground is propwash.
If intending to carry out a low tow, maintain station above the
slipstream until the tug is positively
established in a climb. Then move gently but positively down through the
turbulence of the slipstream
until the turbulence ceases. The glider is now in the low-tow position.
Once again the slipstream is the
primary reference. Do not go too low in relation to the slipstream - it
is not necessary. "

Hi Adam;
Interesting. We are a mandatory low tow club. I thought that all clubs
in Australia were likewise.

High tow all the way, so much easier - and definitely gives you more options
in the early stages of the tow.
