Airspeed trend

Change target or thrust

Make a small, controlled thrust or speed-target change appropriate to the active mode.

In stable flight, note actual speed, selected speed, thrust and the trend indication.

Acceleration indication

Watch the actual airspeed and its trend before it reaches the target.

The current speed, target and trend describe different aspects of the situation.

Target and mode

Return to a stable condition if the aircraft approaches an operating limit or the response is not understood.
