IFACARS is a desktop application that tracks your Infinite Flight flights, logs them, and stores them, so you can keep a log of your flights with detailed performance and route. It also provides useful graphical guidance while you fly, like Runway Guidance that displays the runway you are on or Glideslope Guidance that displays your airplane position on the glideslope.
IFACARS is currently in its early development stage. I'm keeping this Trello board to better organize the development plans, so if you want to follow along, you can track it.
