Approach chart - "LOC"

Hi,

Anyone knows what does the "LOC" in the approach chart symbolise?

It would be easier to see the whole chart. LOC can mean Locater = NDB, but why repeat that title at LOM and with different altitudes? It can also mean LOCALISER (LLZ) and thus be crossing altitudes for a Glide Slope out LOC only approach. I would expect there to be a DME v ALT table as well as these 2 waypoints.

Please show the whole chart.

The height you should be at during a LOC only approach.

Rat, I think L designates the locator. Don’t see it much these days though.

The old step-down charts were always much clearer.

I would also say it's the LOC-approach step down altitudes.

ICAO Abbreviation and Codes are in ICAO Doc 8400

LOC means Localiser

These are Localiser check/step heights

Rat5 the Locator beacons (NDB) are indicated as LO (Outer marker) and LM (Middle Marker) on ICAO Charts. Most of these have been removed and now just have the check heights with a DME reference. I see this chart still uses LOM and then MM and IM which are non-ICAO standards
