Fly as frequently as possible. As with any other activity that requires learning new motor skills–such as tennis or skiing–the less time that elapses between your lessons, the more newly-acquired skills your brain and body will retain from the previous lesson. As a result, you’ll be able to spend more time during each lesson learning new skills instead of re-learning old ones. We find that flying at least once a week is the minimum desirable frequency; flying two or three times a week should enable you to earn your certificate in closer to the FAA minimum times.
Come prepared for your flight lessons. Always complete the reading and know what to expect during your flight lesson, and how to perform any new maneuvers. Make a list of any questions that you have, and bring them with you to the lesson so you can discuss them beforehand with your CFI.
