PPL meaning in Military and Defence ?

A private pilot licence (PPL) or, in the United States, a private pilot certificate, is a type of pilot licence that allows the holder to act as pilot in command of an aircraft privately (not for remuneration). The licence requirements are determined by the International Civil Aviation Organisation (ICAO), but implementation varies widely from country to country. According to the ICAO, it is obtained by successfully completing a course with at least 40 hours (45 in Europe) of flight time, passing seven written exams, completing a solo cross-country flight (minimum cumulative solo flight time is 10 hours), and successfully demonstrating flying skills to an examiner during a flight test (including an oral exam). In the United States, pilots can be trained under Part 141 of Title 14 of the Code of Federal Regulations, which allows them to apply for their certificate after as few as 35 hours. However, most pilots require 60–70 hours of flight time to complete their training. The minimum age for a student pilot certificate is 14 for balloons and gliders, and 16 for powered flight (airplanes, helicopters, and gyroplanes). 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 from age 14, and powered aircraft from age 16.
