The fplan application is designed to assist general aviation pilots in creating flight plans for cross country flights in powered aircraft. It reads a planfile containing a description of the flight; departure and destination airports, navigation aids, intermediate waypoints, winds aloft, fuel consumption rates, and produces a flight plan including; wind corrected magnetic headings, distance, estimated time and fuel consumption for each leg, latitude, longitude and VOR fixes for each checkpoint, etc. A graphical preview of the flight is available on systems with X11 Windows and the XView Toolkit.
fsv, the 3D File System Visualizer, allows you to view a collection of directories and files as three-dimensional geometry. It represents all or part of a filesystem as a collection of blocks of varying sizes, each labeled with a filename, and arranged in a manner consistent with the original directory structure. fsv can visualize any arbitrarily large collection of files, limited only by memory and hardware constraints. Program features include an integrated 2D interface, intelligent camera handling, and extensive use of animation. fsv requires OpenGL.
FXT is a C++ library containing code for various fast orthogonal transforms (Fourier-, Hartley-, Walsh-, Haar-, Wavelet-transform) and convolution. It contains a large collection of low (bit) level routines and combinatorial algorithms (permutations, combinations, necklaces, de Bruijn sequences). Number theoretic transforms and modular arithmetics are implemented. Operations on binary polynomials and arithmetics in finite fields GF(2^n) are included. The package contains more than 150 short programs that demonstrate how to use its functionality.
g2 is an easy to use, portable and powerful 2D graphics library. It provides a comprehensive set of functions for simultaneous generation of graphical output on different types of devices. The following devices are currently supported: Postscript, X11, FIG (xfig), PNG, and JPEG using the gd library, and Win32. g2 is written in C (ANSI) and additionally has Fortran, Perl, and Python interfaces.
Garble is a console program for downloading data (waypoints, proximity waypoints, tracks, and routes) from Garmin GPS receivers. Garble is based on a portable library that implements most of the Garmin communications protocol, and supports most Garmin GPS receivers. Garble can also read the current time and postion from the GPS, get the product data, and turn off the GPS. Garble has been tested on a GPS 12XL (firmware 3.53) and a GPS III .
