What type of flight can a student pilot conduct with an SCA?

A student pilot with a solo cross-country endorsement is permitted to conduct solo flights, making the highlighted answer correct. This qualification allows the student to fly alone without the need for an instructor aboard the aircraft, demonstrating their ability to effectively operate the aircraft independently.

Solo flights are crucial for student pilots as they provide them with the opportunity to practice and build confidence in their flying skills in a controlled manner. The regulations set forth by the FAA specifically authorize solo flights under the limitations prescribed during the training, ensuring that the student has the necessary capabilities to execute such flights safely.

In contrast, other provided options—such as conducting cross-country flights with passengers or night flights with an instructor—are not permissible under a student pilot's privileges until the necessary endorsements and licenses have been obtained. Instructional flights are typically conducted with an instructor present, and specific privileges regarding carrying passengers or flying at night are not granted until the student achieves a higher level of certification beyond the student pilot stage.
