The Eye exams are surprisingly easy in China. The big problems are BP, EKG, Blood/Urine tests, Color ultrasound in the abdominal area for kidney stones and other internal organ anomalies. The Foreign pilots have a substantially higher failure rate than Chinese Captains. The check is also every 6 months. The CAAC docs expect pilots to be astronauts. Don't come to China if you have any health problems and don't expect much job security here. We are simply short term paid mercenaries. If the economy burps in China Ex Pats will be the first to sent packing. Internal politics, tedious ATC flow control and lack of social life make China EXTREMELY difficult for most Ex Pat pilots.
