CBSE 12th

Hi Darshan,
Yes, you can, however, there is a risk. Though you can pursue the CPL training, you may not be easily accepted by any airline for the role of a pilot. Preferred height is more than 5'7 (minimum). There is no point investing in a course and not getting the ROI. You may look for ground jobs or aviation management jobs. There will always be scope within the aviation industry if you have the passion.
Good luck.
