Yup... I know of 4 expats that have made it through the medical. They did their medicals in BLR. It took one chap 1 day, and another 4 days with additional testing.
High failure rates as the majority are being bestowed with TMUs or Temporary Medically Unfit slips. A 12 week period is given to the poor unfortunate to rectify the problem and return for a re-evaluation. The problem is that the Indian Air Force has only their guidelines to follow concerning acceptable parameters. There are no age or demographics curves to adjust their parameters.
The mystery is whether or not an additional TMU will be granted or an actual grounding will be issued. A permanent grounding may have dire consequences on one's future... even at prospective carriers of employment in a different country with background checks and all.
Good luck to one and all.
