All pilot and co-pilot training should be completed before they are allowed to fly a passenger-filled scheduled airline aircraft.
On-the-job training during a fully occupied scheduled airline flight subjecting unaware passengers to greater risks and danger should be prohibited. International safety regulations should enforce the restriction of such training.
All passengers should be entitled to know in advance the qualifications of their pilots and other important inflight crews.
Perhaps passenger plane pilots should be required to compile a certain amount of hours flying cargo planes before they
are given the responsibility of safeguarding human life.
