AirWrench, Copyright (C) 2004-2015, GWBeckwith





The original version of AirWrench is no longer available for download from this website.  Existing AirWrench activation codes do not expire, and current installations of AirWrench will continue to function normally for the life of your computer.  Please note that existing activation codes are only valid on one computer, and the program cannot be moved from one computer to another. 

In addition, note that installing a different version of Windows, and this includes the free upgrade to Windows10, will more often than not change the AirWrench serial number and deactivate the program.

AirWrench was released more than 10 years ago.  The program has been updated hundreds of times over the years and updates and activation code support for registered users have been free to this point in time.  The phase out of Windows 7 and transition to Windows 10 may make it necessary to charge a fee for activation code support in the future.  For now, registered users can still obtain support for activation code issues via the email address shown at the top of this page. 


AirWrench2, available exclusively at Flight One Software, is an evolutionary update that adds four new graphic display pages of AIR file coefficients and modifier tables:

AirWrench2 performs the same AIR file analysis and generation functions as the original, and given the same inputs, will generate the same flight model.  The added pages provide additional flight model insight without requiring any additional data or editing.

AirWrench2 uses the Flight One Software wrapper system, eliminating the need for serial numbers and activation codes.

The new AIR file editor AirWizEd is included in the same release with AirWrench2 at no additional cost.  AirWizEd has the same look and feel as AirWrench, and the same flight model performance analysis capabilities, but it replaces the automated AIR file generation logic of AirWrench with a more traditional, manual approach to editing AIR files.  Each AIR file coefficient is identified by name and can be edited individually.  All AIR file tables are displayed graphically, and each table entry can be edited by keyboard entry or by point-and-click.
