Proper control of aircraft attitude is the result of proper use  of the attitude indicator, knowledge of when to change the  3.  Cross-check the performance instruments to determine  if the established attitude or power setting is providing  the desired performance. The cross-check involves  both seeing and interpreting. If a deviation is noted,  determine the magnitude and direction of adjustment  required to achieve the desired performance. 4.
