The invention provides a method for displaying RNP (Required Navigation Performance) parameters of an aircraft. The method comprises the following steps: computing the estimated position, transverse RNP value and vertical RNP value, transverse NSE (Navigation System Error) real-time value and vertical NSE real-time value as well as transverse FTE (Flight Technical Error) limit value and vertical FTE limit value of the aircraft at the current time, and displaying an aircraft icon, a cross ruler for representing the RNP values as well as an FTE limit frame for representing the FTE limit values, wherein the transverse side length of the FTE limit frame corresponds to the transverse FTE limit value, and the vertical side length of the FTE limit frame corresponds to the vertical FTE limit value. The invention also provides a method for replacing the cross ruler by using a rectangular frame. The invention also discloses a corresponding system for displaying the RNP parameters of the aircraft as well as the aircraft comprising the system. The method and system provided by the invention can be used for visually monitoring the RNP running state of the aircraft in the three-dimensional space.
