The airspeed range between Vno and Vne isn't a noman's land, but conditions have to be good to go there. Getting back from there might be a challenge, too.
The G-loading diagram is overlaid with predicted gusts, the dashed blue lines, and now becomes a gust envelope. It still shows the various airspeeds with which we are concerned, but 15- and 30- fps gusts also are depicted, plus their impact on the airplane's structural loading. The idea is to operate at a speed where a representative gust will not result in structural damage or failure. You can't guarantee that in the yellow arc.
One instrument almost all aircraft have is an airspeed indicator. Of course, it’s important to know how fast we’re going, if for no other reason than bragging rights, and that’s true for airplanes, rotorcraft, gliders and even dirigibles (hot air balloons need not apply). Piston-powered personal airplanes, meanwhile, often have a bunch of color-coded markings […]
