As the performance capabilities of the aircraft are learned,  a pilot interprets the instrument indications appropriately  in terms of the attitude of the aircraft. If the pitch attitude  is to be determined, the airspeed indicator, altimeter, VSI,  and attitude indicator provide the necessary information. If  the bank attitude is to be determined, the heading indicator,  turn coordinator, and attitude indicator must be interpreted.  For each maneuver, learn what performance to expect and  the combination of instruments to be interpreted in order  to control aircraft attitude during the maneuver. It is the  two fundamental flight skills, instrument cross-check and  instrument interpretation, that provide the smooth and  seamless control necessary for basic instrument flight as  discussed at the beginning of the chapter. 6-14
