Instrument Failures

The missed approach point on a localizer-only ILS––depending on the subject

approach plate––may be identified with a TACAN/DME mileage in addition to stopwatch

timing to/from the FAF. According to the FAA, ILS localizer-only missed approach

points should not be “identified” only by means of a MM beacon; however, a MM may

be depicted on published approaches. These MMs may, or may not, be collocated with

missed approach points. (Note: If a MM is coincident with the localizer-only missed

approach point, the pilot should execute a missed approach if the MM beacon

illuminates prior to expiration of timing from the FAF).

Any alternate means [in addition to timing from a FAF] used to determine a localizer-

only missed approach point should be clearly published on the approach plate;

approximation and guessing are not allowed.

If for whatever reasons you switch to another type IFR approach, your IFR approach

minimums may change. Stay alert.

should you do next?
