Walk me through how a 5,700kg + aircraft engaged in ‘commercial’ operations - e.g. aerial work - is legally able to land somewhere that does not have an instrument approach.
No problems, as long as it’s daytime.
ENR 1.4
A flight operating under the IFR by day may be planned to a non- instrument procedure destination provided that the aircraft can be navigated in accordance with ENR 1.1 Section 4.1
ENR 1.5
An aeroplane with a MTOW greater than 5,700KG operating under IFR by night may only be planned to a destination which has an approved instrument approach procedure for which the aircraft is appropriately equipped and the pilot is qualified.
