You are rght about the DGCA regulation. The regs says that the first officer need a minimum of 50 hours on type a sim check and to fly with a captain who is cleared for assisted take off and landing before they are allowed to t/o and land. For captains, if it is their first command they require 1000 hours on type.
When I joined airlines in India I had close to 4000 tt, previous experience of flying CRJ but I was not allowed to land A320 until I completed 300 hours on type. In 2006-7 requirement was 300 hours on type which is reduced to 50 now. Typical
