From the Lion Air Ops manual:
Second In Command (SIC) is only allowed to become a Pilot Flying (PF) after reaching a 300 flight hours on the aircraft type flown (on type)
SIC with more than 300 flight hours on type, may become the PF on takeoff, but to become the PF for landing, he/she restricted to approach using an instrument landing system (ILS).
Especially for Boeing 737-900 ER, with the degree of difficulties because the length of the aircraft, SIC may become a PF after reaching 500 flight hours on type.
An extreme caution must be exercised anytime flying with less experienced pilot. The PIC must be prepared to take over the flight control, especially during takeoff and landing when the SIC is the PF. PIC must keep soft touch on rudder pedal, control column and thrust levers.
When the PIC has less than 300 flight hours on type. The PIC is not allowed to entrust the control to the SIC, irrespective of the SIC total flight time on type.
