Give your Chief Pilot a letter of resignation dated one day prior to your final
TMU outcome decision. Tell him he's welcome to shred it if you pass and keep you on.
If he doesn't like the option you can stand by your resignation...no 'medical refused' - ergo - no stain on your 'record'.
I agree with most that the DCGA not qualifying me medically is seen by most of the world as a joke. Try explaining that to the HR lady at Delta who is handling your application though and is calling Jet Airways HR for your previous employment status.
