Final Answer:
Separate a Cessna 152 conducting a PAR behind an H/C-17 by 3 miles. Option A is the answer.
Step-by-step explanation:
When conducting a Precision Approach Radar (PAR) for a Cessna 152 behind a larger aircraft like an H/C-17, maintaining a safe separation distance is crucial. In this scenario, the appropriate separation to ensure safety is 3 miles. This distance allows for proper spacing between the two aircraft, considering the different performance characteristics and speeds of a small aircraft like the Cessna 152 and a larger one like the H/C-17.
Aviation regulations and guidelines prescribe specific separation criteria to prevent collisions and ensure the safety of air traffic. The 3-mile separation is a standard distance used to provide a margin of safety during approach procedures, allowing both aircraft to navigate and land safely.
Option A is the answer.
