What should a pilot do if the "CANOPY" warning light illuminates?

When the "CANOPY" warning light illuminates, the appropriate action is to confirm the integrity of the canopy and follow the established emergency procedures outlined in the BOLDFACE section. This procedure is critical because a warning light related to the canopy could indicate potential risks such as an unsecured canopy, which could pose a danger during flight.

By confirming the integrity of the canopy, the pilot ensures that it is properly secured and there are no compromises to cabin pressurization or visibility. Adhering to the BOLDFACE procedures helps to standardize responses to emergencies, minimizing risk and ensuring safety.

The other options do not adequately address the situation; ignoring the warning could lead to more significant issues, attempting to change altitude or lower the landing gear may not resolve the potential problem, and could further complicate the emergency without first assessing the canopy's condition. Thus, correctly acknowledging the warning and following the specified BOLDFACE procedures is essential for safe flight operations.
