FSX NumberPad Control (NpC). NpC v2.21 - some small changes from v2.2 including a script you can use to switch autopilot input between Nav and GPS, the ability to set the PMDG B777 Mach window, and instructions on re-sizing and re-positioning the NpC message window. NumPad Control (NpC) is a program for entering Com, Nav and ADF radio frequencies, Transponder codes, VOR OBS/CRS settings, Auto-throttle airspeed, and Autopilot altitude, vertical speed, and heading values in FSX using the keyboard number-pad instead of mouse click spots. NpC is programmed primarily for aircraft with default FSX avionics (radios, transponders, and autopilots that were developed within standard FSX programming guidelines). However, this updated version of NpC also supports a number of third party add-on aircraft such as the PMDG 737NGX / B777, Flight1 King Air B200 and the A2A Cherokee 180. NpC is a set of Lua scripts and thus requires a registered copy of FSUIPC4 to work. An installation and configuration manual is included in the file set. By Al Klayton Dan Sullivan.
