Find all airports between 50 and 100 kms from a location

Question

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!

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.
