So for indicated airspeed Vy decreases as we go up in altitude and Vx increases. Got it.
However the graphs from the PHAK and in an Aerodynamic book that I'm reading show that Vy increases if you are looking at True airspeed.
My question is first, why is this... and second, why talk about indicated airspeed, Vx and Vy meeting and then show graphs that only show True airspeed?
What am I missing?
-Thanks in advance as always
