Do You Need A G-Meter?

摘要

The standard, generic, FAA-issued V_G diagram, above, does a pretty good job of explaining an airplane's speed ranges, the airspeed indicator's color coding and what can happen when we stray outside the normal operating range. However, its scale is based on indicated airspeed, not calibrated or true speeds. As this article's main text notes, an aircraft's never-exceed speed (V_(NE)) is expressed as a true airspeed. When considering this diagram, however, it's important to remember the airspeed indicator doesn't tell us the load factor we're experiencing at a given moment. Only a G-meter/accelerometer can do that,
