Plain English Meaning

A named point on an approach chart that sits exactly 1 mile from the runway's localizer antenna, as measured by the airplane's distance-measuring equipment. When the cockpit display reads 1.0 from the I-SNA station, you are at this fix.

Full Definition

A specific fix on an instrument approach procedure defined as the point located 1 nautical mile, measured by Distance Measuring Equipment (DME), from the I-SNA localizer antenna. The 'I-SNA' identifier refers to the localizer ground station serving the runway (in this case, the ILS at Santa Ana / John Wayne ), and the '1 DME' portion specifies the from that station at which the fix is .
