What is the duration of the Anti-Ice ground test?

The correct duration for the Anti-Ice ground test is 20 seconds. This specific duration is crucial for verifying the effective operation of the anti-ice systems before flight. During this test, activating the anti-ice system for the specified time allows the crew to ensure that the system responds appropriately and that any potential ice accumulation is managed before takeoff.

Choosing the correct duration is essential for safety, as an insufficient test might not reveal any faults in the anti-ice system, potentially leading to issues during flight. Understanding this procedure is vital for flight preparation, and adhering to the specified 20 seconds ensures compliance with operational standards set out by the manufacturer and aviation regulations.
