When is service not required in accordance with the 7110.65?

In the context of the 7110.65, which serves as the primary reference for air traffic control procedures, the situation in which service is not required is when deviations assist emergency aircraft. The rationale behind this is that handling emergency situations takes precedence over routine air traffic management.

When an aircraft is in distress or requires urgent assistance, controllers are expected to provide necessary services to ensure the safety of the emergency aircraft, potentially allowing for deviations from standard procedures or routing. This prioritization underscores the importance of safety in air traffic operations.

In contrast, other conditions such as excessive traffic, unavailability of radar, or poor weather conditions do not inherently exempt air traffic controllers from providing service. Instead, protocols are established for managing traffic under heavy conditions, mitigating the impact of radar outages, and ensuring safe operations in adverse weather.
