IndiGo pilots being probed for using expletives during flights op
At least seven IndiGo pilots are being investigated by the Directorate General of Civil Aviation (DGCA) for using expletives on 121.5 MHz while operating flights in protest against the delay in restoring their pre-Covid salaries.
If proven guilty, the pilots may lose their commercial pilot licence. The 121.5 MHz frequency during radio transmission is used as a “guard” frequency, to be used only in an emergency and it has to be compulsorily monitored by the air traffic controllers who are in the vicinity of the aircraft.
