Which system has priority over the Predictive Windshear Alerts?

• A. TCAS
• B. EWS
• C. ATC windshear alerts
• D. None. PWS alerts have highest priority.

Answer: (D)

The key idea here is how warning systems prioritize alerts for immediate flight safety, especially for windshear. Predictive Windshear Alerts come from the weather radar and forecasting logic and warn about windshear conditions that could affect the aircraft ahead of time. Because this is a forward-looking, direct hazard to the ongoing flight path, it is treated as the most urgent cue, designed to take precedence over other windshear-related or external alerts. Other systems like TCAS warn about traffic conflicts, and ATC windshear notices come from external sources, while EWS provides windshear information from the radar, but none of these override the onboard Predictive Windshear Alerts. Therefore, no system has higher priority over PWS; PWS alerts have the highest priority.
