LZSO Toolkit
The Complete Landing Zone Survey and Assessment Platform
Built by Landing Zone Safety Officers, for Landing Zone Safety Officers.
LZSO Toolkit combines the tools, calculations, references, and reporting functions required to survey, assess, and brief landing zones into a single mission-ready application. Whether you're evaluating a dirt strip in austere conditions or conducting a routine survey, LZSO Toolkit helps streamline operations and improve decision-making in the field.
No spreadsheets. No paper calculations. No juggling multiple references.
Everything you need is in one place.
