All such marks remain the property of their owners.
Official CAP and ICS forms, if reproduced by the software for print, are used solely so a mission can produce required paper. Reproduction of a form for that operational purpose does not transfer any right in the form, and does not make this software an official Civil Air Patrol product.

Radio operation, logging accuracy, form completeness, and compliance with Civil Air Patrol regulations, FCC rules, and other law remain the sole responsibility of the operator and the incident command.
Printed CAPF 110 and ICS 214 output is a convenience for the mission file. It is not a substitute for current official forms, current CAP regulations, or the judgment of the incident commander.
