I have never flown an aircraft in which side-slipping was recommended
for
cooling - what type are you thinking of?


Pawnee ex-crop duster, used for glider towing.
This was the manufacturers advice.


It isn't in the owner's manual.

Colin Bignell


It was never intended/designed to use it towing gliders.
Lots of take offs and landings/descents from around 3000'.
Our grouse was that the front cylinders wore out before the rear.
Even though the air is ducted.


Interesting - I've towed with a Pawnee 235 and, once the post-release 10
seconds had been dealt with (and the CHT was below 200, I think) then
there was no need or recommendation to do anything other than fly it. I
can't recall the descent power settings or speed but the aim, as with
all towing, was to get back ASAP while controlling the rate of cooling
with power/speed, going no faster than Va (a bit of loading helps) and
keeping eyes out. The ROD was "adequate" without sideslip.

The view in the landing attitude was unusual, but very good compared to
some tailwheel types, so no unnatural actions are needed.
