Each aircraft has a chart of v-speeds, critical speeds to be remembered and honored depending upon the phase of flight. This one is for sim use only, but good enough for our purposes.
Note rotation speed is 85 knots - that’s the speed at which you would pull back on the yoke to get the plane off the ground.
Note best angle and rate of climb speeds. You would use one or the other to reach planned altitude for cruise.
At 150 knots - you’re just 6 knots shy of maneuvering speed which supports abrupt (gross control) movements. But for rotation at 85 knots and say, a best rate of climb at 105 knots, you’re way over the tested and intended v-speeds.
