Master fire danger and behavior calculations in the field with a TI-59.
This manual explains how a handheld calculator can compute NFDR indexes and key fire behavior variables, using a custom read‑only memory (CROM) for the TI-59. It covers three practical operation modes and contrasts two standard fuel models used by fire managers.
The book presents step‑by‑step instructions for entering data, selecting the NFDRS program, and obtaining outputs. It also explains the limitations of the model, training needs, and how to interpret results for real‑world fire management.
- Three operational modes to compute NFDR indexes and fire behavior indicators
- Guidance on entering station data, weather inputs, and fuel models
- Worked examples and data storage tips to help you apply the method
- Clear notes on limitations, training requirements, and practical use in the field
Ideal for readers involved in fire planning, weather analysis, or field assessments who want portable, calculator‑based tools for fire danger and behavior estimates.
