How should an instructor log the flight training received by a student?

An instructor should log the flight training received by a student in a personal logbook to maintain an accurate and comprehensive record. The logbook serves as an official record that documents each flight lesson, the topics covered, the duration of the flight, and the progress the student has made. This is important not only for tracking the student's learning progression but also for future reference, as it can be invaluable for both the student and the instructor during evaluations or when preparing for check rides.

Using a personal logbook ensures that there is continuity and consistency in the logging process, as it is an established practice within the flight training community. It allows both the student and the instructor to review past training sessions, identify areas that may require additional focus, and ensure that the training received aligns with the requirements of the applicable regulations for obtaining pilot certifications.

Other options like logging in the airline system or certification documents do not provide a direct and personal account of the training process and could lead to gaps in documentation that are necessary for tracking student progress and regulatory compliance.
