AOPA's guide, Getting Back into Flying, is updated and online in the members' section. It's intended for any pilot who, for whatever reason, has stopped flying.
"Remember, your pilot certificate never expired," said AOPA Vice President of Aviation Services Woody Cahall. "All you need to start flying again is a current medical certificate and a flight review with a CFI."
Getting Back into Flying can help with that refresher training, no matter how long it's been since a pilot has flown. In addition to providing tips, such as finding a CFI for the flight review, the guide is broken into sections outlining the changes in aviation since a pilot last flew. The newest update to the guide is "If You Haven't Flown Since 2000."
Other sections include "If You Haven't Flown Since the Mid-1990s," "If You Haven't Flown Since the Early 1990s," "If You Haven't Flown Since the 1980s," and "If You Haven't Flown Since the 1970s."
In addition, the online version of the guide contains links to recent articles on flight training and proficiency training from AOPA Pilot and AOPA Flight Training magazines.
