In order of complexity, the uncompensated 'rate of climb' vario is the simplest but less useful, the TE vario is still pretty simple but a ''lot'' more useful, the Netto vario is a fair bit more complex requiring the gauge to know the glide performance of the glider at every speed and ballast load, and the speed-to-fly vario is fairly complex to code as it has to know the Netto stuff plus tables for the optimum speed to fly at different ballast settings and external lift/sink rates. | In order of complexity, the uncompensated 'rate of climb' vario is the simplest but less useful, the TE vario is still pretty simple but a ''lot'' more useful, the Netto vario is a fair bit more complex requiring the gauge to know the glide performance of the glider at every speed and ballast load, and the speed-to-fly vario is fairly complex to code as it has to know the Netto stuff plus tables for the optimum speed to fly at different ballast settings and external lift/sink rates. | ||
Please Note that as of 06/2010 there is now a TE compensated variometer available in FlightGear HEAD: [http://gitorious.com/fg/fgdata/trees/master/Aircraft/Instruments-3d/glider/vario/ilec-sc7 $FG_ROOT/Aircraft/Instruments-3d/glider/vario/ilec-sc7]. It has been implemented for the [http://gitorious.com/fg/fgdata/trees/master/Aircraft/ASK13 ASK13 glider]. (As of 02/2011 there is also a second TE compensated variometer available, implemented for the DG-101G.) | Please Note that as of 06/2010 there is now a TE compensated variometer available in FlightGear HEAD: [http://gitorious.com/fg/fgdata/trees/master/Aircraft/Instruments-3d/glider/vario/ilec-sc7 [[$FG_ROOT]]/Aircraft/Instruments-3d/glider/vario/ilec-sc7].

People interested in adding this instrument to other gliders, will want to refer to the [http://gitorious.com/fg/fgdata/blobs/master/Aircraft/Instruments-3d/glider/vario/ilec-sc7/README_install README_install file]. | People interested in adding this instrument to other gliders, will want to refer to the [http://gitorious.com/fg/fgdata/blobs/master/Aircraft/Instruments-3d/glider/vario/ilec-sc7/README_install README_install file]. |
