I am planning to write to DGCA about it but not sure if going to get reply at all or it will take lot of time to get right info from them. I am also searching around on the website and found this CAR
http://dgca.nic.in/cars/D7B-B18.pdf
I hope all the things are there written init should be enough to get the rating/endrosement
If anything else I need to take care of please advice.
Thanks
