I read something very good in a 1968 737 operations manual recently. It said to plan 320 KTS for the climb and 320 or 350 KTS for descent! Easily know the price of fuel was so cheap back then. I find taht 300 KTS works fairly good in the London TMA. Our ECON descent is 273 KTS which is way to slow, but when I hear jets cruising at 0.74 and then descending at 240 KTS, that's just not right.
High speed all the way
