DGCA accepting applications for the April 2012 session now
http://dgca.nic.in/PN-Online0412.pdf
Here are my suggestions
Keith Williams ( very very important )
1. General Navigation
2. Instrumentation
3. Performance
4. Mass and Balance
Books 1&2 are the most important . Books 3&4 while not that important are now part of the DGCA syllabus so you can expect questions .
IC Joshi should be more than enough for MET
For Instrumentation refer to the Oxford ATPL ( Refer to oxford ATPL for other topics also )
For REGS RK Bali or V Krishnan . Dont forget that REGS also has human factors included . For this best to refer to the JAA ATPL Human Factors / performance books .
The most important part about studying for the DGCA exams is using the knowledge to solve as many questions as you can . Learning the theory is not enough . Only if you put it into practice will you discover the silly mistakes and other tricks
I have given a download link to a free JAA question bank that you can use to study ( sometimes the very same questions are asked )
BayFiles
Also the following website is useful for practice .
Aviation Training
All the above mentioned books and links can also be used for the DGCA ATPL exams as well as to study for airline written exams
And lastly dont forget to refer to the DGCA syllabus so that you make sure you havent forgotten to study a particular topic .
