"Mobile Tower, KATT 820, final approach fix,
three down and locked, for the option."
The name of the FAF may be used, (if there is a name), i.e.
"BRENT Inbound". "For the option" may be replaced by "full
stop", "touch and go", or "low approach" as appropriate.
"Sherman Tower, KATT 820, missed approach,
(with stated reason)."
Reasons may include "runway not in sight" or "lost course guidance." When
Tower turns you over to the Approach Controller, inform ATC of the missed
approach with your intentions.
Intentions may include:
Request the same approach.
Request a different approach with lower minimums.
Request clearance to your alternate.
317. ILS/LOCALIZER APPROACH
An ILS approach is a precision approach utilizing a localizer antenna for transmitting
course information and a glideslope antenna for glideslope information. A localizer approach is
considered a non-precision approach due to non-availability of glideslope information. Notice
that the ILS and the Localizer both use identical frequencies for course information and are listed
on the same approach plate (see Figure 3-10). Because the ILS has glideslope information, the
minimums for the ILS will normally be lower than the Localizer minimums.
ILS or Localizer approaches can be initiated from low or high altitude. Low ILS or
Localizer approaches (found in the Low Altitude Approach plates) are assumed. To request a
HI-ILS approach, you must use the term "HI-ILS." If an enroute descent has been given from
center, you are most likely being set up for a low altitude approach. Requesting an enroute
descent to a HI-ILS would not make sense.
