We have a Pawnee 235HP, most common of tow planes.. there are also 260HP
versions.
Also a CalAir tow plane may work.

We operate from a 2833MSL airport, 3500ft long runway.. normally glider
starts from about 500ft, so that leaves 3000ft of runway to go.. on hot
summer days.. with a 2-33 or a Grob 103 in tow at MaxGW.. we can plan on
200ft at the departure end.

Looking for 300ft in the air at departure end, in a Janus (assume two seats
loaded) at max GW take off from a 2200ft long runway is very optimistic.

I'm not sure what the performance would be with the Wilga... but I'm
guessing not much better.

Our operation has started the hunt for a new towplane.
The main criteria is that from our 2200ft strip at sea level we need
to have a two seater (janus) "over the fence" at 300ft in still air.

What would you recommend?
Dont dwell on purchase cost but rather performance/running costs

We would consider
a) Used
b) New
c) Experimental/anything else.

Thanks for your thorts.

Roy,

You say that you´re looking for a new towplane! What type did you operate
so
far?
A 2200ft strip at sea level and 300ft over the fence in still air with a
Janus in the tow sounds like a challlenge!
I was towed by many different towplanes, but there are very few which can
do
that reliably!
One, which can do the job is a YAK-55 though....however, not the usual
kind
of towplane!

I tow with our clubs Husky and on our 1600ft strip (1950ft above msl) we
are
talking more like 50ft "over the fence" (and much less in the summer) with
a
DG-1000 in the tow.

Good luk,
Markus
