Monitor the altimeter, along with the VSI, to confirm you have set the correct pitch. These instruments suggest pitching down 1/2 bar width on the attitude indicator.
Assuming you have set the pitch correctly to maintain altitude, monitor the airspeed indicator to confirm you have set the correct power. With this indication, try adding some power to re-establish the intended 110 knot airspeed.
Monitor the heading indicator, along with the turn coordinator, to make sure you have set the correct bank. This deviation suggests a momentary 5° bank to the right to re-establish the intended 270° heading.
