Also dot commands are our friends.
You start a dot command by typing a dot  (period)  .
This tells the radio buffer that your doing a command, NOT talking.
The period  "    .   " HAS to come first, followed by the command name, then variables. 
Example, quick way to exit sortie is 
.ef  (exit flight)
To move to field A7  
.move 7
Simplicity itself  

 Just leave the A, V or P off.
to change country 
.country 1 (for bish, 2 = knight, 3 = rook Shudder, god forbid you'd go there)
To set planes autoclimb speed (Alt X)
.speed 123
