Current Sectional Charts and Terminal Area Charts are necessary for pilotage and dead-reckoning. They also contain invaluable information about airspace. Downloads are available from the FAA website. However, you should always have a paper copy available. Paper copies can be purchased from almost any flight store. Electronic versions are included in many apps such as ForeFlight or WingX (note: many of these apps require an annual subscription). Charts are valid for 56 days and you are responsible for having a current, up-to-date version. *Note: Amazon does NOT generally offer the best prices for Sectional Charts and TACs. Shop around!
