What happens if the canopy is not fully in position?

The scenario where the canopy is not fully in position poses a significant safety concern, particularly regarding the ejection system. If the canopy is not properly secured, it can prevent the ejection mechanism from operating correctly in the event of an emergency. The ejection system relies on the canopy being either fully closed and latched or properly configured to ensure a safe and effective ejection of the pilot and/or crew. A partially closed canopy could obstruct the ejection path or interfere with the pilot’s ability to eject safely, increasing the risk during a critical situation.

In contrast, while the aircraft may have systems that will not operate optimally due to other factors, the main concern with a mispositioned canopy is its direct impact on the ejection system’s reliability. The starting of the aircraft, the functionality of flight instruments, or modes of operation like standby are less directly affected by the canopy position compared to the fundamental need for the ejection system to function accurately when required.
