  • Flarm clock screen with acoustic  warning when connected to FLARM device
  • Much additional information can be  displayed - such as average, thermal vario, netto, time, speed…
  • Many custom audio settings
  • Speed to fly indication
  • Several useful variometer readings
    can all be displayed on the same vario scale: Instantaneous Vario (outer red  pointer), Average Vario (red diamond), MacCready Setting (Blue arrowhead), Thermal  Average (Green “T”) making it easy to compare the achieved average and thermal  climb rates with the MacCready setting.

S7 Two seat setup

 

The S7 has a rear seat repeater (S7D). The second unit is more than just a repeater display; it has all of the same functionality as the main unit. Front and back units are connected together with a CAN Bus cable carrying both data and power. One of the great features of the S7 is its connectivity for a PDA or Oudie including power and data from the main unit. You can also drive a second rear seat PDA or Oudie using a CAN2PDA box. This small box connects into the CAN Bus between the front and rear S7D and provides data and power to the second PDA or Oudie. Parameter changes from PDA to and from the S7 vario are possible such as MacCready, QNH etc.
