Product catalog summary
CNv Encoder Operation
  • Upper Left (UL) Encoder: Navigates screens; fast CCW spin shows Cruise/Climb screen, fast CW spin shows Settings screen.
  • Lower Right (LR) Encoder: Controls vario volume, changes flight and setup parameters, and selects display screen set.

Flight Screens
  • Climb Screen: Displays 20-second and total climb averages, reset upon cruise/climb switch cycling.
  • Cruise Screen: Shows Netto value, STF, and wind direction/velocity.
  • Mac Cready Screen: Adjusts MC value and calculates STF using various parameters.
  • Winds Screen: Displays wind direction and strength.
  • NAVIGATE HOME Screen: Requires home coordinates; shows direction and altitude differential to home.
  • Ballast Screen: Displays AUW in liters or US gallons.
  • Bugs/Clean Screen: Adjusts bug coverage and displays impact on L/D.

Glider Settings
  • ALT/GPS Screen: Adjusts altimeter setting.
  • OAT: Allows manual entry of outside temperature.
  • Margin Height: Adds altitude margin for HOME calculations.
  • Dry Weight: Defines dry weight including pilot and equipment.
  • Polar: Selects or defines glider polar.

Vario Settings
  • Pointer and Audio Response: Adjustable time constants for pointer and audio.
  • Cruise Response: Controls STF chevrons and netto averages.
  • TE Source: Selects between TE probe or electronic TE.
  • TE Compensation: Adjusts based on TE source selection.
  • UTC: Sets UTC offset for local time display.
  • Volume and Backlight: Adjusts audio level and screen brightness.
  • Gear/Spoiler Warning Activation: Activates warnings with ADC connections.
  • ZERO POINTER: Positions mechanical pointer at zero.

Tools
  • LOGBOOK: Views prior flight details.
  • Profile: Selects profiles transferred via USB.
  • ADC Connections: Supports gear/spoiler warnings and cruise/climb switching.

Vario (CNv) Quick Reference Card-1

CNv Quick Start Card - Club Software - Version 2.6.2362 CNv Encoder Operation Upper Left (UL) Encoder Navigates left/right to desired screen. Normal rotation scrolls through all screens sequentially. A fast CCW spin always displays the Cruise/Climb screen. A fast CW spin always displays the Settings Screen Lower Right (LR) Encoder Controls vario volume in Cruise/Climb Screen. Changes Flight parameters (MC, Bugs, Audio Volume, etc.). Supports Setup parameters (Glider Model, Weight, Constants, etc.). Selects Display Screen Set (Flight, Settings, or Info). Climb Screen - 20 Second Climb Average - The top row displays the average climb rate for the last 1,2 .. 20 seconds - Total Climb Average - The lower row shows the average climb rate for the total climb duration. Max duration is one hour. - Both values are reset to zero when the manual cruise/climb switch is cycled. - When automatic C/C switching is in use the screen typically switches to Climb at about 45 degrees or one eighth of a turn. The two averages and the timers however are reset after the first few degrees of any turn so that if/when the vario goes into climb mode the averages (and the timers) display values from the first point at which turning was detected. Cruise Screen - The Netto value is the calculated vertical speed of the airmass based on the last 1 - n seconds of cruise flight where n = cruise time constant. The timer shows duration from the start of the current glide. - Average can be N or RN, depending on option chosen in Utility. - The STF is dynamic using selected flight parameters (polar, ballast, bugs and MC) and vertical air mass motion. - Each chevron corresponds to a five knot difference between the indicated airspeed and the speed-to-fly - Wind direction and velocity are displayed lower right. Mac Cready Screen - The MC Value is adjusted using the LR encoder. - The STF is calculated using the MC setting, ship polar, dry weight, ballast, and bug % entered by the pilot. This is the STF in neutral air. Glider Settings
