If you haven't added new ratings or certificates, consider doing it. It's a great way to bring romance back into your relationship with aviation. There's a wide range of ratings you can add to your private certificate. You can get a rotorcraft/helicopter rating, rotorcraft/gyroplane rating, lighter-than-air airship rating, glider rating, free balloon-hot air rating, free balloon-gas rating and a powered lift rating. If you're gun-shy about taking written/computer knowledge exams, you'll be relieved to know that for all these additional ratings, you're not required to take one to add a rating if you already have a pilot certificate. Nevertheless, you can expect the oral portion of the practical test to be pretty comprehensive.
