Consider:
E6-B does altitude correction, which corrects indicated altitude to true altitude, based on non-standard temperatures.
Also, AIM 7-2-3(d) refers to altimeter errors when the temperature is extremely cold, without regard to pressure altitude. (E6-B uses pressure altitude.)
Now:
Are these two items referring to the same errors, or are the two different types of errors?
If I'm 1000AGL over a 10,000' airport at -10C, the E6-B yields a correction of about 10' (makes sense, since I'm close to standard temp). The AIM TBL 7-2-3 indicates a correction of about 100' -- Why?
In both cases, there is zero error when I'm on the runway, because altimeter settings are "cooked" to make that true.
