Embodiments of a method are provided that may be carried out by an avionics display system deployed on an aircraft and including a monitor. The avionics display system receives position data indicative of the aircraft's detected position from at least one data source. In one embodiment, the method includes the steps of: (i) attributing an error characteristic to the data source, (ii) identifying an airspace assigned to the aircraft at a given time, and (iii) establishing an error-compensated airspace as a function of the error characteristic and the assigned airspace. The aircraft's actual position remains within the assigned airspace provided that the aircraft's detected position resides within the error-compensated airspace. A visual representation of the outer boundaries of the error-compensated airspace is generated on the monitor.
