Airbus FMS Bias

[Tan]

Good Day To All

Does anyone know the Airbus FMS 'bias' in respect to the GPS? Is the 'bias', a constant or a variable (blend)?

With the increase in runway incursions, would it be much of a stretch, to assume that Airbus and Boeing have plans to include runway taxi display's on their ND's?

Many Thanks
