Flying into Biggin IFR is not easy at the best of times, due to the proximity of Heathrow,CITY, Stansted Luton Gatwcik etc ++ all in the same area- it is a very busy area!
Perhaps you can qualify that statement?
We share much of our IFR arrival procedures with City airport. Are you saying that flying IFR into City is also 'not easy' also?
