If an airfield's RWY length is not known (e.g. EGMJ - Little Gransden) then the airfield is not displayed unless the "Hide Airfields with runways shorter than:" option is set to zero.



I would prefer that such airfields are always shown regardless of this setting.

I don't want to add an option because I think that in the UK, turning it on would undo a lot of the work undertaken by hiding the short runways in the first place. Which airfield(s) in particular are you concerned about, apart from the one you already mentioned?

I like using this feature to turn off a lot of farm strip airfields. If there were an option to keep airfields showing for which we have no runway data, a lot of them would reappear if it were enabled.
