How are anti-ice and windshield heat indications verified during flight?

• A. Check indications on cockpit panels and ECAM; ensure anti-ice systems are commanded when icing conditions are present.
• B. Visual inspection only.
• C. Not necessary in flight.
• D. Only check after landing.

Answer: (A)

In flight, you verify anti-ice and windshield heat indications by actively monitoring the cockpit indicators and the ECAM (ECAM/ECAM pages) to confirm the systems are supplying heat when needed. The anti-ice status is shown on the cockpit panels (switch positions and status lights) and on ECAM, which displays which surfaces are heated (engine and wing anti-ice) and flags any faults. Windshield heat is likewise indicated through its own status indicators and ECAM messages.

The key is to ensure that when icing conditions exist, the anti-ice switches are commanded ON and the corresponding indications confirm that heat is being supplied. If the ECAM shows a fault or a surface is not heated as commanded, you would follow the abnormal procedures. Relying on a visual check alone isn’t sufficient in flight, and icing can occur without obvious visual cues, so continuous confirmation on the panels and ECAM is essential. Post-landing checks do not substitute for in-flight verification.
