The requirements of a flight review state that a minimum of 1 hour of flight instruction and 1 hour of ground instruction are required to complete that review.
My question concerns the logging of that activity. In the past my instructors have given me an signed logbook entry for the flight time, a description of the training received and materials reviewed a logbook endorsement stating that the flight review was performed. Most logbooks have a section for ground instruction, but I've never logged specific ground time there during a flight review. For a flight review to be valid does the ground instruction actually need to be logged separately from the flight instruction? Or is the ground instruction implied by the endorsement?
