Is emergency flap operation available when the auxiliary battery is the only source of electrical power?

The operation of emergency flaps typically requires a certain level of electrical supply to function correctly. In many aircraft systems, emergency flaps are designed to operate using main battery power or an alternate source that is more robust than what an auxiliary battery provides. The auxiliary battery is often not sufficient on its own to handle the power demands of operating emergency flaps.

Therefore, the assertion that emergency flap operation is available when the auxiliary battery is the only source of electrical power is inaccurate. While some systems may allow for limited operation under certain conditions, in general, reliance solely on the auxiliary battery would not facilitate normal or proper operation of the emergency flaps. This means that under average conditions without a main power source, emergency flaps cannot be deployed, affirming the statement is indeed false.

The other options suggest nuances or situational dependencies, but the primary understanding is that adequate power is crucial for such critical systems to operate safely and effectively.
