Tasman Vario on Static

[Tony[_5_]]

OK, I'm 99% sure that this won't be an issue but everything in the
literature for the Tasman vario's says it only needs connected to a
total energy port. No total energy on the Cherokee II but I suspect
the tasman will work OK hooked to static just like my current Winter
vario. It will just be non compensated as expected. Is there any
reason why this wouldn't work?

This has been mentioned before on this board, but connect the Taz to a
separate static line, or ensure there is a good length of line between
the two (Tee connected in back of the seat)

Tony, get a TE probe! Dick Johnson had an excellent article in
Soaring a few years ago on mounting a TE probe on a PW-5, and there
was an article many years ago on how to make one.

Or go find an old glider that isn't being flown anymore and borrow
one!

Kirk,

I had a probe on the Cherokee before I recovered it last winter. I
built the probe from the Dick Johnson article. I'm not sure that it
ever really made a difference. When recovering I decided to just go
back to static for simplicity and not having to poke a hole in my new
fabric. Plus some discussion with Dave Nadler here led me to believe
that having total energy in a glider that weighs 600 lbs and cruises
between thermals at 60-65 mph really isn't all that necessary. I can
do my best zoom climb and still not gain a whole lot of altitude. I
wasn't able to detect much of a difference in the response from my
Winter vario with or without the TE probe. So I think that with my
lightweight, low L/D, low wing loading, low speed glider I am not
placing a TE probe install very high on my to do list. Higher
priorities are rewiring with Tefzel and getting an audio vario in the
panel as I'm planning to fly the Region 10 contest this year. Plus
there are these bubbles on the leading edge which probably don't
affect the performance one bit but are annoying me.

Well it would seem that total energy is not required if I folllow this
post.
All I can say is that any speed variations without TE will lead to stick
lift and will make it much harder to centre that thermal as a small back
pressure on the stick will show lift and vice versa
Basic TE is nothing to do with interthermal flying speeds but reduces the
vario indication changes due to speed variations whilst circling rather
than lift.
In my view absolutely essential!(unless you can circle with no speed
variation at all)

I'm well aware of the advantages of total energy and the affect of
stick thermals. Like I said, I previously had a TE probe on my glider
and could not tell a difference with or without it installed. Perhaps
the static system on my glider sucks, perhaps the TE probe that I
built was worthless, perhaps it just didn't make a difference in my
glider. Either way I managed to have many long duration and distance
flights with my uncompensated winter vario and was very happy with how
it performed. Now I would like to add a nice new audio vario to my
panel.

So....

Does anyone know if the Tasman V2000 will function normally when
hooked up to the gliders static port?

[Paul Remde]

Hi,

I agree. I think it is extremely tough to rely on the variometer reading
when trying to center a thermal if you don't have a TE probe. Also, it is
tough to know whether a thermal you encounter while cruising is worth
stopping for.

Yes, I'm biased because I sell them, but that is my honest opinion.

Hi Tony,

Yes. Any vario (including the Tasman V2000) will work fine when connected
to the TE Probe (for TE compensated static) or directly to the static port.

Paul, since you sell V2000's, and I intend to buy from you anyway, do
you know if it will work on Static or is TE an absolute requirement
for the vario?

[Tony[_5_]]

Excellent, thanks, thats what i thought but wasn't sure if there was
something funny with the Tasman. Obviously they assumed that anyone
flying with a nice audio vario would also have a TE probe when they
wrote their manual. I have proved them wrong! :)

btw this thread reminds me of this classic story http://www.jimforeman.com/Stories/varios.htm

After yanking the TE probe out of my glider i managed to fly twice as
many hours as any previous season along with two 300km+ days and get
my gold badge last year. I came within 4 miles of diamond goal.

Think of what you would have done if you had TE!

Tony,

A TE defiantly makes a difference in light weight glider, and the
Johnson probe did much better for me on my 1-26 than a store bought
probe did on the tail.
A couple of notes, I mounted it just behind the removable rear canopy
on my 1-26B, and I made it somewhat higher than Johnson did in the
article to get it out of the dirty air from the cockpit. Also,
mounted a permanent tube that it fits down into, so I could experiment
with different lengths of TE to make sure it was in clean air.

Hi Tony,

Kicking it old school?

I learned with a static vario, and last year for grins, decided to
take my Winter (quick) alogrithmic vario off the TE probe and connect
to the static port. I left it that way all year. It is not difficult
to understand what is going on with a sailplane and the air it is
going through. Thermalling as a 15 year old was not difficult without
a compensated TE vario and still isn't. It was also interesting when
I turned off the audio on my electric one day. The tactile sense (seat
of the pants) in thermals became much more pronounced without the
constant audio tones, and felt much more in tune with what the air was
doing, not what my audio vario was telling me it was doing.
Interesting, of course modern quick TE/Netto varios make for faster
and more efficient cruising, but not necessarily a more emmersive,
soaring experience.
