Atmos 1.2   (details) 49/50 ENG   68KB/7KB
ScreenshotLibrary for atmospheric/air speed computations, intended for aeronautical engineers and students. It can be used to compute atmospheric properties (temperature, pressure, density, and kinematic viscosity) and acceleration of gravity from altitude and, vice versa, to obtain the altitude corresponding to the value of one of these quantities. Using the altitude and an air speed related quantity, the library can compute (for both subsonic and supersonic regimes) True, Equivalent and Calibrated Air Speed, Mach number, Dynamic Pressure and Reynolds number per unit of length. Finally, the library can be used to compute "kink altitudes", i.e. altitudes corresponding to intersections on an aircraft airspeed diagram between constant Mach number lines and constant True/Equivalent/Calibrated Air Speed lines or constant Dynamic Pressure lines. Through the use of a reserved variable content, it implements a method for Non Standard Day Temperature correction. The library supports both SI units and Imperial units. Two versions of the library are provided (one for the 49G and one for the 49g+/50g) as well as a text documentation file to be loaded on a SD card and used in conjunction with the SDIAG library (see the Emacs package). Completely written in System RPL.

USOLVE 1.8   (details) 49/50 ENG   242KB/14KB
ScreenshotUtility program that was designed to complement the built in Multiple Equations Solver (MSOLVR). USOLVE functions will allow the user to create their own unique equation libraries in a directory. Users can add comments or add units to equation variables. The Mpar titles browser can display titles for all subdirectories in the parent directory that contains Mpar; the user can then quickly launch the MSOLVR menu. Whenever a single equation or lists of equations are stored, USOLVE creates or updates Mpar automatically, which means less organizing variables for the user and faster execution of MSOLVR menu. It also maintains the order of variables and updates variable text as the user changes, deletes or renames equation variables.
