A system for presenting performance attributes on a display unit on an aircraft is disclosed. The system may include a communication module for receiving the RNP for the aircraft, a navigation module for determining the position of the aircraft as well as its ANP, and a processing module for generating an integrated graphical representation of these performance attributes. The processing module may generate a cross-sectional depiction of a virtual tunnel based on the RNP and the position of the aircraft, wherein the cross-sectional depiction may include a first containment limit indicator and a second containment limit indicator. The processing module may also generate an aircraft position indicator, wherein the aircraft position indicator may indicate the position of the aircraft as well as the ANP of the aircraft. The cross-sectional depiction of the tunnel and the aircraft position indicator may be displayed on a display unit in a two-dimensional manner.
