IFR: whom do you talk to?

[kevenv]

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.

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?

It is class G right up until 17999. At 18000 Class A begins. (in the Southern control area anyway)

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.

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.

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.

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.
