Ok...but then let's suppose a situation. We apply a certain amount of power to the throttle and we're climbing at 250 knots. To those 250 knots there is a corresponding dynamic pressure. As we increase in altitude, pressure decreases which means that the dynamic pressure would also decrease which means our IAS would tend to decrease as we increase in altitude.
I think this idea what I have is wrong so can you please tell me where I'm going wrong as this is getting me confused now.
