When the auxiliary battery is the only source of electrical power, what is the status of flap operation and position indication?

In scenarios where the auxiliary battery is the sole source of electrical power, flap operation and position indication are typically not functional. This is because flap systems require more extensive electrical support to operate properly and provide accurate status feedback. The auxiliary battery generally does not supply enough power to maintain normal or emergency operations for flaps, which include moving the flaps to various positions as necessary for flight operations.

In this context, "normal operation" refers to the standard capability of the flap system to both position the flaps and provide real-time feedback on their status, while "emergency operation" entails a reduced capacity often designed for use in critical situations. However, when relying solely on the auxiliary battery, the system doesn't retain the capability for either full operational modes. Therefore, the correct choice reflects that neither standard nor emergency functions for flap operation or indication can be maintained under these conditions.
