Airports in Close Proximity but different identifier

[hugel]

I am trying to define a means to select airports on a screen map with a cursor. It has occured to me that there could be two airports in very close proximity (or even the same airfield) that have a different name or identifier which would make discrimination difficult.

Is it often the case that if airfields with different identifiers are shown colocated on a chart, such as airfield with a mix of military and civil traffic for example ? Do you have any examples that would illustrate this ?

Of great help would even be a link to an airport list with coordinates so I could calculate the proximity myself....

Any help is much appreciated.

Honolulu is PHNL, Hickam AFB, located on the west side of PHNL is PHIK. The only one I can think of, off hand.

The best examples I can think of are:

Schwäbisch Hall
eddh.de - Landeinformationen
eddh.de - Landeinformationen

Treviso (about 3 runway lengths, but close enough)
eddh.de - Landeinformationen
eddh.de - Landeinformationen

A little creative SQL gets me to:

Of course some of those, like St Mawgan and Newquay, may simply be renamings -- though it looks like they moved the ARP 100 ft when they did that!

I think hugel is really looking for co-located airfields, which happens when the civvies and the military use the same runway, with the civil terminal on one side and the military base on the other side.

Athens (Glyfada / Hellenikon ?) somehow sticks in my memory.

From personal knowledge,
LFPV | VILLACOUBLAY VELIZY | LFPN | TOUSSUS LE NOBLE
is not a very good example, One is a big military base, the other is a small GA airfield, several miles away.

LFPZ | SAINT CYR L'ECOLE | LFPN | TOUSSUS LE NOBLE
ditto, they're small GA airfields miles apart.

EGDK | KEMBLE | EGBP | KEMBLE
sounds better... co-located civil and military.

KELP and KBIF are close enough, one shows up on the other's taxi chart.

I think hugel explained the background quite well. As someone who has developed software for plotting airports on a map, I can testify that all that matters is the proximity of the ARPs. aerolearner's Brescia example is a good one -- Treviso is the one that I remember because I wanted to display both airports on a map of the whole of Europe, on which scale 5 miles is just a few pixels.

I didn't check Belgium but that's a particularly good example because they quote identical ARPs. At no scale would representations on a chart be separated.

If you had visited the Prague AeroExpo in May you would have found yourself at Prague Letnany airport LKLT, which is not quite co-located with Kbely airbase.

I think they are about 70 miles apart but have heard that there have been incidents where SNA and SAN have been forced into the FMS Init Ref page thus causing an obvious error.

Hugel,

Chitose (Military, although sometimes used for Civil alternate ops I believe) and New Chitose (Civil) are located on the same airfield, and share the same terminal. They are RJCJ and RJCC.

They have different ARP's at
N42 47` 40.00 E141 39` 59.00
and
N42 46` 31.00 E141 41` 33.00

openNav :: RJCC - New Chitose Airport

The google earth picture shows the two runways on the right as the Civil, and the ones on the left as the Military.

There are links to aerodrome charts on the page.

Good ones, I should have known! DFW and ICT areas have numerous airports in close proximity, if not co-located.
