Lunacy .... Yes , but there are so many idiotic rules around that nobody takes notice of and this is just one more !
Out of interest who is going to enforce this ? You can currently fly into an airport that is declaring IFR and be VFR .... Nobody actually asks what viz and cloud base you had on the way in . As always the helicopter community will just accept it , as it has all the other nonsense over the years , and that will be another nail in the coffin ......and this coffin has already been shut firm for 10 years or more !!!!
