Summary
👤
Senior🎓
Top SchoolLance Bays is a Senior Lead Aeroperformance Engineer with nine years in his current trajectory and over two decades of hands-on experience developing clean-sheet and derivative aircraft from concept through certification and sustainment. He blends deep aerodynamics and performance expertise with software and method development—authoring and maintaining performance modeling tools in C++, Python, FORTRAN, MATLAB and more—to bridge analysis, flight test, and production. His career spans defense and commercial programs at Boeing, Lockheed Martin, Gulfstream, General Atomics and NetJets, where he led trade studies, wind-tunnel campaigns, and bespoke airfoil and flow-control solutions. Lance has a track record of turning conceptual ideas into testable hardware and production-ready data, including updating FAA-approved manuals and embedding performance models for operational use. He also steered a standardized C++ performance model for SaaS deployment and cultivated university partnerships for advanced research, revealing a blend of practical engineering and program-level innovation. Based in Edwardsville, Illinois, he pairs academic grounding from Georgia Tech and the University of Arizona with a pragmatic, systems-minded approach to improving aircraft capability and operability.

GalaxyHobo/AeroToolKitAddIn
Mar 2019 - Aug 2019
Excel add-in with functions to perform common aeronautical engineering calculations, including standard atmosphere, airspeed, aircraft performance and unit conversion calculations. Includes non-standard day calculations (ISA deviation). The add-in is written in VBA embedded in AeroToolKit.xlam. Atmospheric calculations are based on the ICAO standard atmosphere (reference ICAO doc 7488, dated 1993). This add-in derives from an earlier add-in by the same original author, stdAtmo20140121. This new add-in standardizes naming conventions and adds functionality. To install the .xlam file, go to File | Options | Add-ins, and navigate to the location at which you wish to keep the add-in on your file system. NOTE! There seems to be an issue with Excel "remembering" add-ins that it has loaded, particularly with Excel 2019. If this is a problem, go to the Add-ins menu (File | Options | Add-ins), select Manage Excel Add-ins, and uncheck the Aerotoolkit add-in and click Ok. Then return to the menu and re-check the add-in. The .xlam add-in consists of a single module, AeroToolKit, which is exported from the .xlam to the text file AeroToolKit.bas and maintained in the repo. Other essential elements of the repo include the function list with descriptions, AeroToolKitFunctionList.xlsx, and a full test of all functions (including expected results), AeroToolKitTest.xlsm. For configuration management, observe the following procedures: 1) Changes to the functions in the AeroToolKit.xlam file must be exported to the text AeroToolKit.bas file. 2) New functions or changes to existing functions must be accounted in an update to AeroToolKitFunctionList.xlsx. Export a copy of the file to the equivalent AeroToolKitFunctionList.csv in Excel. 3) Create new tests of the function in AeroToolKitTest.xlsm. Potential users concerned with the security of downloading and using an .xlam file from the internet can create their own add-in and import AeroToolKit.bas. If they are particularly nervous, they can review and copy the source in AeroToolKit.bas from GitHub and create their own .bas file.
