Below you will find brief information for variometer S7 Version 4.90, variometer S7 S7D. The LXNAV S7 is a standalone digital variometer and final glide calculator, capable of receiving data from both GPS and PDA/PNA systems. The unit can be expanded through a CAN bus to one or more repeaters (LXNAV S7D). The unit has a bright 2-inch color display readable in all sunlight conditions, featuring a mechanical needle driven by a stepper motor that indicates vario, netto, relative or speed to fly value. The unit also offers 100Hz sampling rate for quick response, speed to fly indication, and TE compensation for both pneumatic and electronic TE probes. The LXNAV S7D is a rear seat device that can be connected to the main unit via a CAN bus and provides both pilots with equal control of all functions.
