When using suggested routes when departing BIKF to some destinations the G3 airway is present. This airway is not allowed to be flown by departures from BIKF. Could the recommendations be tweaked?
That’s not entirely true. G3 is available for planning for aircraft with short-range navigational equipment only(VOR etc).
However, 99% of the aircraft coming to and departing from KEF should not be filed via G3, and it would be handy if Simbrief didn’t suggest G3
Yes you’re right. But who flies those types of aircraft anyway haha 
99% should not fly G3
