Air Traffic Skills Assessment (ATSA) Practice Test 2025 - Free ATSA Practice Questions and Study Guide

The correct answer is based on the concept of radar contact. When an aircraft is radar identified by Air Traffic Control (ATC), the necessity for the pilot to report over compulsory reporting points is alleviated. ATC uses radar to monitor the aircraft's position continuously, which allows them to provide separation and guidance without having to rely on position reports from the pilots.

This is an important aspect of air traffic management, as it enables a more efficient flow of traffic and reduces the communication workload for pilots. In the absence of radar contact, pilots are required to report at these points to ensure ATC has a clear understanding of their location and intentions.

The other options, while relevant to air traffic protocols, do not remove the obligation to report at compulsory points in a similar manner. Reaching cruising altitude and entering controlled airspace are moments that don't inherently affect the need for those position reports unless ATC has established radar contact. Contacting the destination airport pertains to communication related to landing procedures, not to the standard reporting obligations while en route.
