  A New Vario With Some Differences

The Tasman V1000 Vario
Phil says "After playing aeroplanes all week as a maintenance manager for Ansett Airlines of Australia, I have accumulated 1200 hours (playing aeroplanes) since starting gliding in 1982". He is a member of Beaufort Gliding Club, operating from Bacchus Marsh Airfield 35km from Melbourne, Australia, and flies the Libelle VH-GBP he rebuilt from a wreck acquired in 1989. He is a cross-country and performance coach specialising in sports psychology. Club Class competitions play an important role in his flying agenda. Phil's best distance is 617km and he has been placed 2nd and 3rd in the 1995/1996 Club Class Nationals.

Trying out a new vario can mean having to let go habits you have been trying to refine for a long time as it is the combination of flying skills and aircraft response to vario activity that determines how well you climb and glide.

Malcom Crampton , the designer of the Tasman V1000 vario and fellow club member, asked me to try out a production variometer, one year after the prototype release. I have been using a Cambridge L-Nav, GPS-Nav combination for some time and thought I used it fairly well.

Installing the V1000 is extremely simple. One electrical connection and one tube connected to the TE, prior to any filtering used for other varios. Oh yes, cut a 57mm hole in the panel. To give it the best shot I mounted it top centre in the panel to use as the primary centring vario. This proved more than a simple task as my Libelle has very little room for extra instruments in the panel. Three panels layouts later the task was completed.

The V1000 uses pressure sensing technology along with altitude compensation, programmable smart gust and response filtering and displays a liquid crystal -10 to +10kts segmented display. Press the red button to turn on and the unit displays all sequences and audio before settling on a display of the meter and numerical averager. The averager is continuously displayed and in flight remained in unison with the Cambridge to 0.1kts displayed.

The yellow button selects variables, response time 1 to 4sec in 0.5sec increments. Audio mode allows silent sink tone below 0 and sink tone. Lift tone above zero is about twice the sampling rate of the Cambridge and is enhanced at the 0 to 1kt range so that positive small responses are not missed.

Some clever programming is included so that erroneous gusts are not over running the positive small indications. This is very evident when thermals are entered in the gust zones immediately before the core is reached. This is the area you feel when we are saying "get ready, climb ahead".

Audio volume and battery voltage can be displayed by pressing yellow or red and yellow buttons together. Does it work out in practice? The answer ís yes, very well. Not too many bells and whistles to confuse the early flyer but operationally sound to give excellent confidence to when to turn in t
