@shon - I did that.. and id urge everyone whose got exams to go study themselves. I finished both conversion exams aka CPLCG AIR NAV COMPOSITE & REGS in the 2nd attempt. The first attempt was just a trial as i had just landed back frm training like 2 days before the exam so thats like a negligible attempt.
Anyways i studied using GSP's (Ground Studies for Pilots) for NAV / Radio Aids / Flight Planning & MET(4 books), RK Bali's book for AIR REGS and also Reading up DGCA CAR's / AIP / Act of 1937 etc.
Books are available at English Book Store in Delhi. You can buy the GSP for NAV and Air Regs by RK Bali primarily then once done with those go onto Flight Planning and Radio Aids
It took time and lots of looking here n there and a lot of breaking the head on the wall lol. but i did get thru..
To pass the DGCA Exams you also need lotsa luck by your side.. ! But anyways go ahead with this. Im sure a lot of people have done this and aced. If you work hard nthn will be able to stop you from getting done with the exams.
Try K C Duggal's(Dy Dr DGCA, Ret) notes, worked out for a lot of us. But you never know what DGCA might ask on each specific paper. Last year a composite paper had lots of POF questions in it and this year one of the reg exam was full of human factors. So better arm yourself with everything you can find. All the best.
I personally feel that the GSP's are very poorly written....I prefer reading up from oxford for better understanding of the topic...The matter is well written and includes some humour here and there.... For examination point of view go through question banks e.g. Pooley's, volare, PPSC ( i am trying to find this one out....last attempt tech. paper was from this one ).... Websites like exams4pilots (Met. last 2 attempts) and turbinesturbines The list is long....So get your hands on as much material as you can and keep reading everything you lay your hands on. If there is any specific topic you need info on, Let me know, I'll be glad to assist with regards to the reading material...
P.S. CP PNR questions are still being asked...Flight planning not so sure..
The UK company PPSC closed for business many years ago now. Therefore anything you find produced by them will not be current in the context of JAA questions but will always provide excellent practice on basic concepts.
