The terms are interchangeable generally and I've seen an output defined to have this or that full scale deflection (although strictly speaking it should be defined as full scale and not FSD). As a rule of thumb, to minimize DME slant range error, how far from the facility should you be to consider the reading as accurate? Correction is made until the vertical needle centres, meaning the aircraft has intercepted the given course line. Connect and share knowledge within a single location that is structured and easy to search.

Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site. Simple deform modifier is deforming my object. Localizers supporting Category II/III service must be tailored., As such I would say that if your needle goes full deflection you are no longer on course and thus no longer legal under 91.181 and dont know how far you are from the course anymore so you have no way to know how to intercept it (even if you practically know where it is) but going missed allows you to easily establish yourself on the missed course (if you have two CDI's your likely tuned in already anyway or should be). I'd like to note that my original missed point was that the transition was "Smooth" over that 2NM period as the question cites the same point in the AIM that I've used as an answer later on with my own improved overall understanding.
