How many annunciators from this list are typically illuminated: CANOPY, GEN, OIL PX?

In the context of the T-6A aircraft, the annunciators are visual indicators that alert the pilot to specific system statuses or malfunctions. The question specifies three annunciators: CANOPY, GEN, and OIL PX.

When considering these particular annunciators, under normal operating conditions, it's common for at least two out of the three to be illuminated. The CANOPY annunciator indicates whether the canopy is closed and latched securely; the GEN (Generator) annunciator typically illuminates when there's an issue with the electrical system, such as a failure or abnormality in generator output. The OIL PX (Oil Pressure) annunciator indicates a problem with oil pressure, which can be critical for engine performance and safety.

In a scenario where the aircraft is operating properly, the CANOPY might not be illuminated if the canopy is secure. However, issues could arise with either the generator or oil pressure indicators that could lead to their illumination during flight operations. Therefore, it is reasonable to expect that both the GEN and OIL PX could be illuminated under certain conditions.

Understanding that at least two of the provided annunciators frequently signal alerts about the aircraft's systems confirms the answer of three as the number of illuminations typically seen, as this includes situations where
