OnePanel features


OnePanel development is frozen. Code works and can be used, but is no more maintained.
OnePanel is an avionic device for Flight Simulator 2004 and Flight Simulator X. It is an “All In One” remote command for radios, EFIS, MCP designed to work initially with the Boeing737, using FSUIPC. Code and hardware licence is General Public Licence.
The goal of the NPanel device is to provide quick access to functions that need to be clicked, for example, the MCP, radio frequencies setting or Gear lever and indicators.


OnePanel driver runs on Windows (tested on winXP SP3 only). It is written in C++, to be fast and easy to maintain. Access to Fligt Simulator variables is provided by Peter Dowson’s FSUIPC (fantastic) library.

  • Radio Tuning Unit allow radio frequency direct tune and EMIT/RECEIV selection,
  • Mode Control Panel allow Flight Management System functionnalities quick access,
  • Performances display gross weight, external temp and pressures.
