    Once the airplane is clearly climbing and not likely to settle. I use either visual indications or the VSI going from negative or zero to indicate a positive value on a missed approach, go around, or takeoff. My mantra on a missed approach is power, pitch, positive rate, gear up.

    Yup! Two indications. Altimeter and VSI. Always verify.

    Keep in mind that the VSI indication will show an immediate change in vertical direction, but lags by about 6-9 seconds in showing the actual rate of climb/descent due to airflow restriction of the calibrated leak. Practically speaking this means that once the needle starts moving upward you will have established a positive rate of climb. So the indication for positive rate I teach is the needle moving upward. It does not have to be at zero or above. I believe this is particularly important when executing a missed approach in IMC as you want to get the aircraft cleaned up and climbing as quickly as possible.

    to maintain a “positive rate” you must have a safe and stable airspeed with an indication of altitude gain ie: ALT or VSI , a low and decreasing airspeed means you are converting airspeed (kinetic) into altitude (potential)
