What is the first phase for assessing the airfield to identify pavement damage quickly?

The first phase for assessing the airfield to identify pavement damage quickly is the initial reconnaissance phase. This phase is critical as it involves a quick visual survey of the airfield to effectively identify visible signs of damage. During the initial reconnaissance, assessors can make preliminary observations regarding the condition of pavement, which aids in determining whether more thorough evaluations are necessary. This phase is designed for speed and efficiency, allowing for rapid decision-making on follow-up actions, which is essential in maintaining flight operations and ensuring safety.

The other choices represent different types of assessments that are typically more detailed and systematic, which follow the initial reconnaissance phase if further investigation is warranted.
