Is there reference material available that can predict how much Flight Technical Errors can affect aircraft positional accuracy while in GPS based navigational flight?

Greetings,
No material describing such prediction (FTE), GPS or DME/DME or ILS sensors dont matter, what matters is that ANP(Boeing) EPU (Airbus) is smaller than RNP for that particular area.
In fact today the aircraft position doesnot matter at all, the hole concept is based on a sphere containing the aicraft, the aircraft position within the sphere dont matter, however the diameter of the sphere MUST always be smaller than the RNP, that can be visualized as a tube

For example, if a WAAS-based autopilot flight plan intends for an aircraft to be at a particular place at a particular time, to what degree will FTEs affect the ability of such an aircraft to acheive the intended placement?
Does WAAS govern aircraft accuracy regarding runway approaches or does this fall within LAAS coverage?
Thanx.

Yes, FAA made measurements on their 737.Roughly the azimuth error is directly proportional to distance from localiser. I am presently in UK and return to US next week, where the data is , .if you e-mail me I will send it to you by e-mail My e-mail is [email protected]
