HB73,
the first segment is between achieving Vtoss and 200 ft, when OEI. It is certainly not the limiting segment for the 212. For the Clear area Cat A profile, the TDP is 56 kts at 35 ft and this is then the subsequent Vtoss in the event of an engine failure. The predicated rate of climb is 100 ft/min using 2.5 minute power. However, 56 kts is also Vy - the speed at which the second segment is climbed at. This segment requires a 50% increase in rate of climb but at a reduced power setting - MCP OEI. There is no drag reduction from raising undercarriage either, unlike wheeled types.

Obviously, then, the second segment is the limiting factor for Class 1 Performance (using the clear area procedure.)
