There are many visual illusions that can present themselves during flight. One scenario that can mess with the normal cues during the approach and landing phases is a runway that is located on a hilltop.
I recently flew into Catalina airport on Catalina Island to enjoy one of their fantastic buffalo burgers. While the airport is a fantastic place to visit, it does present special challenges and many local flight schools require a special checkout in order to land their rental airplanes at Avalon.
