False virus warnings!
Be aware that F-Secure, Sophos, Symantic and TrendMicro are showing false virus warnings. This is because of the DLLs included in the application that provide a keyboard-hook to enable system-wide shortcuts. Additionally, to reduce file size, the applet is compressed using UPX. This can also lead to false virus warnings.
Your All-In-One Solution

The FSX 15 applet is a Logitech G15 keyboard applet to display almost every information of your flight directly on your keyboard LCD. It requests more than one hundred different things from FSX.

Features include but are not limited to: display of your airspeed (TAS, IAS, Mach), altitude, vertical speed, fuel, icing, damages, flaps, battery status, heading & course, position, wind speed & heading, weight, electrical power.

The applet also includes a "flight warn system" that warns the user about strange things that are going on. It is also possible to configure the behaviour of certain aspects of the application. The FSX G15 applet is still in development and newer releases contain even more displays, more functionality, better configuration and OS support.
