- Identify airtanker base issues, develop solutions, and recommend corrective actions to the National Interagency Aviation Committee (NIAC).
- Support standardized training for airtanker base operations and provide leadership in training course development, implementation, evaluation, and revision.
- Ensure that airtanker base standards are consistent with member agency procedures, practices, and expectations.
- Serve as a central source of information, guidance, and support for national and geographic area airtanker base decisions and operations.
