Firefighter 1C Wildland Practice Exam

Which of the following is NOT a hazard for air tankers?

1. Steep topography

2. Gentle rolling hills

3. High winds

4. Dense smoke

The correct answer is: Gentle rolling hills

Gentle rolling hills are not considered a significant hazard for air tankers. When flying over such terrain, the challenges faced by aerial firefighting operations are considerably reduced due to the relatively gradual changes in elevation. This allows for better visibility and flight stability, making it easier for pilots to navigate and perform their drops safely. In contrast, steep topography can create difficult flight patterns and increase the risk of accidents because of abrupt elevation changes, while high winds can severely affect control and accuracy during water or retardant drops. Dense smoke also poses considerable challenges as it can limit visibility, making it difficult for pilots to assess the fire's behavior and surroundings effectively.
