The National Park Service flies more than 17,000 hours each year, with 60% of those hours flown in support of natural resource-related missions. These complex activities are routinely performed in diverse terrain and environmental conditions. As such, NPS pilots and aviation personnel must constantly hone their skills in various challenging situations under controlled circumstances in different types of training provided throughout the year. Read about and learn about some of the different types of training that aviation personell are required to attend and participate in. The ability of NPS Aviation to provide continuous and quality training opportunities mitigates the risks asssociated to each and every flight.
