AI Technical Summary
Technical Problem
Aircraft equipped with Enhanced Ground Proximity Warning Systems (EGPWS) generate unnecessary alerts during take-off when descending from altitudes higher than the cruise altitude, which can be distracting and undesirable for pilots.
Method used
An avionic system that utilizes cruise and take-off altitude data sources to determine if the cruise altitude is below the take-off altitude, preventing the EGPWS alert mode from generating alerts until the aircraft reaches the cruise altitude, thereby disabling or commanding the alert to be suppressed.
Benefits of technology
Prevents unnecessary EGPWS alerts during take-off, reducing pilot distraction and maintaining operational efficiency by ensuring alerts are only generated when the aircraft reaches the intended cruise altitude.
