OOhh! I like the picture. I think that is an early 727-100, light zero fuel weight. Had to watch that if you were full. You couldn't actually fly with the all the seats full and any cargo. Now imagine a 757 vs guppy argument.
I have flown a 57 for about 12 years. If I remember right, 115 was Vref even at somewhat moderate weights, and it was the absolute minimum. No matter how light, it never went lower. I looked it up a long time ago. Below 115, the control authority was the limiting factor. The actual Vref could have went lower at low weights.
BTW you might not be able to land a 900ER at 175 knots in Denver. I don't have a TAS converter, but you might be over the tire limit speed.
