Colonoscopy is a test which allows the doctor to look directly at the lining of the large intestine (the colon). Diagnostic colonoscopy is recommended for alterations in bowel habits, occult or frank blood in the stool, unexplained anaemia and as a screening test for colon cancer.
To receive a Private Pilot license, the FAA requires student pilots have a minimum of 40 hours of flight time, of which 20 must be dual (flying with an instructor). However, these are MINIMUMS. No one I know completed their training in 40 hours. I took 66 hours.
The minimum age for a private pilot certificate is 16 for balloons and gliders, and 17 for powered flight (airplanes, helicopters, and gyroplanes). Pilots can begin training at any age and can solo balloons and gliders at age 14, powered aircraft at age 16. 1 Issuing authorities.
