Incredibly amazing!
Australian pilots will not be able to believe that aircraft can fly safely in IMC without being "in the system"
With far lower traffic densities in aus no pilot is allowed to enter IMC in uncontrolled airspace without a full position IFR flight plan being filed and making prior contact with ATC to obtain known traffic on other IFR aircraft.
This requirement exists even if flying over the remote Gibson Desert!
The full en route charge must be paid for all IMC flights.
And they normally require the flight details 30 minutes before so they can get the details int the FDP system .
How many mid airs have you had in IMC in uncontrolled airspace?
