Vilas,
Read my post #23 again. TAS and V/S are both speeds, and change at the same rate with ambient temperature.
For constant weight, CAS and thrust, gradient and acceleration do not change with temperature.
I honestly don't understand what figure 21 is trying to show. In figure 18 the weight is 71000 kg, i.e. the climb-limited weight at 35 deg C. In figure 20 (titled "Lower Takeoff Weight ...") the climb-limit weight at 45 C is 65100 kg. What is the weight in figure 21? Why is the gradient constant above 45 C?
