Yes this is the correct place to post..
Going through the training at 16 will not be a problem. One of the guys at the same flying club / school as myself did his first solo on his 16th birthday and passed his skills test a few days after his 17th..
I wish I could wind back time and go that route!!
If you have access to the required funds and can manage to fly at a minimum once a week then you will fly through the course. Consistency is the answer. I have been flying for a year and a half and am about to do my cross country qualifier. The JAR PPL is a minimum of 45 hours though few complete in this time. You will be required to sit 7 written exams and an RT oral. Costs vary by school and probably expect to pay £120 an hour or thereabouts for a Cessna 150.
Take your time and enjoy it.
