Detection range of Spotter aircraft/Fighter

[Echo_519]

What's the range a ship can spot a Spotter Aircraft or Fighter aircraft. Wasn't it set to 10km like most CV-based aircrafts?

Aircraft can spot enemies that are within their concealment range from the aircraft up to a maximum of 20km, I believe.

Yes yes, i know that. But I meant what range can I spot those planes. Those Planes should have their own detectability range... But what value is it? Can't find anything about it over google search...
