Simple question:
If I have just enough power to climb at 150ft/min OEI MCP from 0ft to 1000ft with Vy L/G retracted, will I or will I not have sufficient power to climb from 0ft to 200ft at 2 min power, L/G extended at VTOSS? Suppose that you are using MAX VTOSS
The answer is: Not always for the reasons previously explained in this thread. You noted that you can operate in PC1 at 26,500 lb, at sea level, 32C, using the maximum TDP/Vtoss, but that you have to reduce the gross weight if the temperature goes above 32C. The only way to make the first segment climb requirement not limiting at temperatures above 32C is to increase the TDP/Vtoss. To satisfy your curiosity you should be able to see how much TDP/Vtoss would have to be increased (theoretically) by graphically extrapolating the performance charts.
