You can check that easily (2 clicks) by selecting your craft in the base and look at its range.
FYI for anyone wondering... you have to enable 'RADAR' (default key 'R') in the GEOSCAPE screen which will show base radar and craft radar 'AND' then craft max distance when selecting a target will be displayed. Posting here, because I had no idea this was an option (usually have radar disabled) and it took me a while to start looking for this feature and figure it out only after reading this post. Thanks for the screenshot Meridian.
Super low request, and not necessary, but it would be nice to decouple the hotkeys for the three: base radar, craft radar, and craft max distance.
Probably the easiest way would be by having a separate hotkeys to toggle in the geoscape hotkey options for the three. That way you could set the hotkey for all three as the same key and then the functionality would work like it does now or have separate ones.
I find that I only use base radar when planning and building a new base otherwise prefer not to look at all the radar rings, but I do now use the craft max distance all the time and I often use the craft radar after launching a craft to target or when patrolling to I.D. alien activity. I just never noticed the craft range before because of usually having radar off most of the time. I'd prefer to set the craft radar and max range as the same shortcut as I use them all the time and the base radar as a separate shortcut as I use it seldomly.
