Yes you are right. I guess I have to define what "near a major center" means. Airways above 12,500 up to 18,000 are Class B or the MEA and above. Up north and in mountainous areas though, the MEA can easily be 18,000 feet though. Here is a good website that describes your Class B problem. Better yet, spend an hour with an instructor and they should be able to hammer out all your questions in person. That has to be way more efficient than this. Short of writing out the whole AIM to explain your issues.

IFR: whom do you talk to?

Re: IFR: whom do you talk to?
Examples of Low level Airspace are:RAC 2.8.2
All low level controlled airspace above 12 500 feet ASL or at and above the MEA, whichever is higher, up to but not including 18 000 feet ASL will be Class B airspace.
Control zones and associated terminal control areas may also be classified as Class B airspace.

Control Area Extensions
Control Zones
Transition Areas
Terminal Control Areas
If it is uncontrolled Class G below 12,500 there most likely isn't any class B above. Class E is considered controlled airspace.

Re: IFR: whom do you talk to?
North part of YQM FIR (Bathurst area and even into Montreals airspace) is uncontrolled below 12500 and class B above...BTD wrote:If it is uncontrolled Class G below 12,500 there most likely isn't any class B above. Class E is considered controlled airspace.
Re: IFR: whom do you talk to?
That's why I said most likely. 
Never talk yourself into a corner.
However, more often then not if it is class G low level airspace there won't be class B above. If you're unsure, either look at the charts or try to raise the centre on the PAL prior to going above 12.5.

Re: IFR: whom do you talk to?
Each LO/HI chart has all the Centre frequencies in use for the chart area listed on the legend page, along with the site where the frequency is located (or relayed through). They are also located in the CFS under the city where the ACC is located (ie. Edmonton, Winnipeg, Toronto, etc.)chephy wrote:So there is no publication that lists all of that stuff for you and no sure way to know this without talking to someone, in other words? Aww, too bad.
Pick the closest one - as someone else said they'll tel you if you're on the wrong frequency. After a couple of times you'll get to know the areas covered by each frequency.
Re: IFR: whom do you talk to?
If it's class G below 12500 and as you say, more often than not, there isn't class B above that , what is above the class G where you fly?BTD wrote:That's why I said most likely.

Re: IFR: whom do you talk to?
It is class G right up until 17999. At 18000 Class A begins. (in the Southern control area anyway)If it's class G below 12500 and as you say, more often than not, there isn't class B above that , what is above the class G where you fly?
Re: IFR: whom do you talk to?
I also find it somewhat confusing when trying to figure out exactly who you need to talk to IFR. It seems you need to infer a lot from a bunch of scattered and sometimes vague information. Of course I only have my INRAT done, no doubt I need to talk to an instructor with experience, since it seems thats the only way to really be sure.
Re: IFR: whom do you talk to?
If you start at a controlled airport, you will be handed over frequency by frequency, starting from Clearance Delivery, to Ground, to Tower, to Terminal, to Center, to Terminal, to Tower, to Ground. If you're flying from uncontrolled airspace, looking at the PALs is your best bet (either on the chart directly, or on the front of it). Try contacting the one you think is appropriate. If you get in contact with someone, but you on the wrong frequency, they'll tell you which frequency to go to. Otherwise, if you're not getting anyone, try an other frequency.sstaurus wrote:I also find it somewhat confusing when trying to figure out exactly who you need to talk to IFR.

As for the Class B above 12.5, on the LO charts, everything that is green is uncontrolled from ground to below FL180, green with white square lines is uncontrolled below 12.5, but controlled (Class B) from 12.5 to below FL180, and white is controlled from ground to below FL180 (whatever class below 12.5, and class B above 12.5 to below FL180).
I know only 1 "type" of airspace that is controlled above 12.5 to below FL180 but that isn't class B.

Re: IFR: whom do you talk to?
Thanks for writing it out for me. I was a little lazy. One small addition to this. White on the LO chart might not be to the ground. In the case of an airway, it begins at 2200AGL.As for the Class B above 12.5, on the LO charts, everything that is green is uncontrolled from ground to below FL180, green with white square lines is uncontrolled below 12.5, but controlled (Class B) from 12.5 to below FL180, and white is controlled from ground to below FL180 (whatever class below 12.5, and class B above 12.5 to below FL180).
