How long is an SCA valid once it is issued?

An SCA, or Student Certificate Authorization, is valid indefinitely until it is either revoked or the student successfully completes their private pilot certificate. This means that as long as the student remains engaged in training and has not received a certificate, they can continue to use the SCA for their training purposes.

Typically, this authorization reflects the understanding that the student is actively pursuing their private pilot license and can demonstrate the necessary skills and knowledge. Once the student completes their private pilot certificate, the SCA is no longer necessary. This policy is designed to streamline the training process and provide ongoing support for students as they develop their flight skills.

In contrast, other options suggest a limited timeframe for validity which does not align with the regulatory framework in place for student pilot authorizations. The indefinite nature of the SCA as long as the student is actively pursuing a certificate encourages continuity in learning and training.
