We left a particular aerodrome airspace and was asked to change frequency. Normally on the next frequency we would recieve flight information service. We would be operating under Class C airspace.
The instructor said he wouldn't bother because it annoys the controllers and they have better things to be doing. Also the display on the radio made it difficult to switch.
Okay, there should be no non GA aircraft below Class C, but should we have switched frequency?
I am very low hour PPL
OK I will try to cover the points in order;
1. Were to told to "contact" or to "freecall". If the first then you were obliged to do as instructed unless you were in class E, F or G VFR and told the controller (it has to be a controller to issue instructions) that you were not doing so. It is very important in this case to let ATC know you are not going to call the next frequency because in this case the first controller has passed your details and the second one is expecting your call. One of the triggers for overdue action is a pilot failing to make a radio call when it was expected.
If on the other hand you were told to "freecall" then your details were not passed but it is good practice to let the controller know that you are changing to a different frequency or remaining on the current one or whatever.
If it was not ATC and an Air/Ground or AFISO then they can not issue instructions.
2. Class C airspace?
3. The radio was U/S if you can not set the frequencies. Some King radios have a system whereby if you hold a button in while turning on the radio it will start up on 120.000 and you can then count the clicks to set the frequency but this is an emergency case.
3. In Class G you can have all sorts of traffic....everything from paragliders to A380s....that is the nature of Class G even if it is below a CTA
