I am searching for airports that have ILS (not sure if there is a "law" that any airport servicing civil flights must have one).

So I googled around and found this nice site http://www.azworldairports.com.

So I've been looking at airport in Vienna and in airfield section there is following:

Runway 1: Heading 11/29, 3 500m (11 482ft), 75, ICAO Cat. I, 3B, Aircraft size max: E, Rwy 11, ILS 114, Lighting: 11 CAT 1/PAPI, No Restrictions, Rwy 29, ILS 294, Lighting: 29 CAT 1/PAPI, No Restrictions

Runway 2: Heading 16/34, 3 600m (11 811ft), 75, ICAO Cat. I, 3B, Aircraft size max: E, ILS 162, Lighting: CAT III B/PAPI, No Restrictions

What exactly is ILS 114 / 162 / 294?

  • $\begingroup$ @J.Hougaard Indeed. The vast majority don't have it. $\endgroup$ – reirab Oct 7 '16 at 20:24

That's the ILS heading to the runway.

Based on how runways are numbered, runway 11's heading will be somewhere between 105° and 114°, 114 nails it down.

  • $\begingroup$ @Kyslik It'll be stated on the approach plate, examples here. $\endgroup$ – ymb1 Oct 7 '16 at 17:38
