What must be true about logbook endorsements?

Logbook endorsements must be signed by a flight instructor to be valid. This requirement is in place to ensure that a qualified individual verifies the pilot's training and proficiency in specific areas. A flight instructor's signature provides legal backing, confirming that the student has met the necessary requirements for various flight-related tasks, such as maneuvering, solo flights, or special endorsements. This requirement reinforces the notion that endorsements must come from someone who is certified and knowledgeable enough to assess the trainee's skills appropriately.

Other choices introduce misunderstandings about endorsements. While flight reviews are an important aspect of maintaining currency, they do require proper documentation and can involve endorsements to reflect that the pilot has completed the review successfully. Virtual instructors may provide instruction, but specific regulations may apply regarding who can sign off on logbook endorsements, often requiring an endorsement from an in-person, licensed instructor. Lastly, logbook endorsements must include specific training details, such as the task performed and the date, to ensure clarity and accuracy in documenting training progress.
