Supplementary question, triadic.
Let's say one of your students is going to fly from The Oaks (near Camden NSW) to Leeton (in the NSW Riverina), 'low level', VFR. The student will overfly Temora. The aircraft has 1 VHF.
In the system you are advocating, what frequency (if any) do you advise your student to monitor and broadcast on, at what positions, during that flight?
Specifics, please.
I'm assuming you won't be telling the student: "It is simply your choice". Or is my assumption incorrect?
