Jeppesen minimums and ALS

Hi guys,

from yesterday the airline I work for started to use EU OPS minimums (Standard on Jeppesen charts).

The Approach light systems are defined as:

FALS (full ALS)
IALS (Intermediate ALS)
BALS (Basic ALS)
NALS (no ALS

depending on the length of the Approach lights. From 900 to 720 meters it's a FALS, from 719 to 420 it's intermediate, from 419 to 210 it's basic and below 210 meters of ALS it's a NALS.

Now, in the Jeppesen minimums section of the approach charts you have:

FULL / LIMITED / NO ALS

Can someone explain the meaning of LIMITED? What is it referred to (IALS+BALS?)

In the Introduction section of the Jeppesen it's not explained, not even in the definition or in the Approach chart legend.

Thank you

BTS

Great! Thank you very much.

So it's not referred to the ALS but to the eligibility to use a RVR less than 750 mt.
