I don't drink, but I'm always nervous when I blow into the tube before every flight .
Recently, a friend at our airline forgot to do his post flight BA on return to India as mandated by the CAR when you operate from an international layover to India. He's currently on a 3 month suspension cooling his heels at home.i believe the DGCA stamps the license as well.
Recently, operated AUH IXE , diverted to BLR due fog at IXE . We had to leave PAX on the plane , take our bags , clear immigration and customs , take a cab to our ops medical room , do the post flight BA and then come back through the same mess to operate BLR IXE. That was a waste of 1.5hrs to do the postflight BA. Too tragic to laugh , anywho we love our red tape that's for sure...
Masa lama and keep blowing negative . Let's make it a compulsory ICAO rule , that should be fun right ?
