So Bloggs prescribes efficiency over safety!! Don’t want the safety improvements that class E provides for IFR aircraft, because it might delay a departure. Of course if it’s VMC the departing aircraft could decide to depart VFR with an IFR pickup thus removing the need for ATC to hold the aircraft, but that’s too difficult for some.
The main excuse given all those years ago, why US style class E wouldn’t work here was because we didn’t have the surveillance at low level. We were the first country to mandate ADSB, there is suitable low level coverage at Mangalore, but it’s still class G as per industry’s demands all those years ago.
Result? 2 IFR aircraft equipped with ADSB and being observed by ATC had a mid air collision in class G.
