Find all airports between 50 and 100 kms from a location

Hi all,

I'm trying to find all airports in radius between 50 and 100 kms from given position. My approach is:

Find all airports in radius 100 kms
"Subtract" all airports in radius 50 kms from result in (1.)

Is this a good way? If not, please, advise me how to do it. If yes, how do I subtract two result sets?

Here is my attempt for airports in 50 km radius from 49.0294417N, 17.4397194E.

Thanks in advance!

One Answer:

Here's an example of naming the result sets and finding the difference:

http://overpass-turbo.eu/s/ucd

[out:json];
(node["aeroway"="aerodrome"](around:50000,49.0294417,17.4397194);
)->.fifty;
(node["aeroway"="aerodrome"](around:100000,49.0294417,17.4397194);
)->.hundred;
(.hundred - .fifty);
out;

I think the approach is fine.

Thank you. Not sure why I had to modify it to http://overpass-turbo.eu/s/ucs to show me all results.

I just omitted ways and relations to save typing for my example.
