Minimal with no HIAL’s

Ltn07 created the topic: Minimal with no HIAL’s

Hey all,

Please correct me if I’m wrong but as far as I can tell the following applies for ILS visibility minima:

0.8km only with HIRL and HIAL available (as well as coupled autopilot, failure warning ect.)

My question is: why have they got 0.8km listed on the DAP charts for runways that don’t have HIAL’s even installed? For example Perth runway 03 ILS-Y.
Surely we can’t use 0,8km here can we?
I may be interpreting this wrong.

Thanks in advance!

You'll have to ask Air Services that one. Maybe they are anticipating the day when HIAL may be added to the system.

According to the YPPH aerodrome chart (below) Rwy 03 has both HIRL and HIAL
