Glass Panals

Youre basking in the glow of your high-tech primary flight display and make a slight attitude correction to level the wings. The bank hadnt even resulted in a heading change because you caught it so quickly.

Key Takeaways:

• Glass panel (EFIS) failures, particularly attitude-related, can present incorrect information on the primary display while other critical data remains, making it highly disorienting and difficult to disregard faulty indications.
• Unlike traditional gauges, faulty glass panel displays often cannot be easily ignored or covered without losing other essential flight information, forcing pilots to actively manage conflicting visual data.
• Pilots must proactively understand their specific avionics' failure modes and dependencies, and practice flying with partial or conflicting information, as system warnings may be delayed.
• Even with advanced internal diagnostics, EFIS systems do not relieve pilots of the responsibility for continuous cross-checking and vigilance to ensure data accuracy, similar to conventional instruments.
