What type of flight instruction record must an instructor maintain for lighter-than-air aircraft?

Instructors providing flight instruction for lighter-than-air aircraft are required to maintain official logbook entries. This requirement ensures that all training activities, including flight hours and the specifics of the training provided, are formally documented. Official logbooks serve as a legal record that verifies the training conducted, which is crucial for both regulatory compliance and the progression of a student's flying credentials.

Maintaining official logbook entries allows for accountability and provides a clear history of training and experience, which can be referenced in future evaluations or during the certification process. It ensures that students receive proper credit for the instruction and flight time they have logged, aligning with regulatory standards set out by aviation authorities.
