how do you access the list of airfields and their radio frequencies???
Yes as skate said more often than not most info you need for tankers and airfields can be found in f10. Click the icon- for tankers sometimes you need to click on the f2 view after clicking on the tanker to get tacan info- which you will be more familiar with later on.
Also when talking to them make sure you are talking on your equivalent to mic switch forward command.
To talk to ground crew in 1.22 you can leave your canopy up and just hit mic switch forward command and go through the menu for ground crew but on 1111 you need to set the rotary dial behind the throttle to INT (inter phone) to talk to them (regardless of frequency). Just don't forget to turn your interphone setting back to where it started (vhf I think).
