Why is econ climb faster than econ descent
Quick question for those on the know. Why econ climb speed is faster than econ descent speed for the same cost index?. Some of the variation can be explained by the heavier weight on climb and even on a given day by differences in wind or temperature. Still in short sectors the weight difference is small and the wind quite similar.
For a low cost index econ climb and econ descent should roughtly equate to best rate of climb/ best glide speeds. In my A/c climb is usually 285kts but descent 255.
Any ideas?
