What's a Trend Vector?

A trend vector is a device, an arrow symbol, that shows the trend of airspeed or altitude over the next few seconds. It's available on the latest flight instruments. It predicts the future, at the current rate of change.

For instrumentation, it's a great advancement, as it allows the airspeed or altitude trend to be ascertained without having to watch the instrument for a few seconds.
