Which statement correctly describes when to provide radar services?

Providing radar services is based on specific operational criteria and safety protocols rather than subjective measures of satisfaction with equipment or arbitrary conditions. The correct perspective on when to provide radar services relies on standardized procedures involving air traffic control.

The service should begin based on the operational needs of aircraft in the airspace, which does not correlate to personal satisfaction or emotional response towards the radar equipment. Offering services based on first-come, first-served principles does not ensure the safety and efficiency of flight operations, as higher priority traffic may need to be addressed first. The notion of starting services as soon as the aircraft is in sight is misleading, as the provision of radar services also depends on the specific air traffic control sector's capabilities and current workload.

Finally, there’s no policy dictating that radar services are to be provided solely during peak traffic hours, as this would not adequately account for the needs of all flights at various times. Instead, the operational protocols for radar services are designed to ensure that all aircraft can receive the necessary support regardless of the time of day or individual traffic conditions.
