Why has the “show airports” option been disabled for flight planning? and why is the radius way too big? 
Specifically, Shoreham airport on the south coast of the UK has an indicated no fly radius of 5.6miles where in reality it should be 2.32miles as indicated here http://notaminfo.com/ukmap - It’s now called Brighton City Airport but show’s the actual air space restriction.
2.9 miles North West of it is a BMFA registered flying site so it’s clearly not right.
