The lack of IAP in one direction (03 is it?) may change in the future!
The slight issue with Gatwick CAS is well documented and not an impossible hurdle to overcome.
Which are both the reasons why Biggin will never become a big commercial airport.
If they ever did want to become a 'big commercial airport' (and I don't know if they ever said they did) they don't any more.
