After that you can speak commands using the following grammar:

digit = "zero" | "one" | "two" | "three" | "four" | "five" | "six" | "seven" | "eight" | "nine";
activateAutopilot = ("activate autopilot" | "switch autpilot on");
deactivateAutopilot = ("deactivate autopilot" | "switch autpilot off");
turnRight = "turn right", digit, [digit], [digit];
turnLeft = "turn left", digit, [digit], [digit];
setSpeed = ["set"], "speed", ["to"], digit, [digit], [digit], [digit];
startDescend = "descend", ["to"], ["altitude"], digit, [digit], [digit], [digit], [digit];
startClimb = "climb", ["to"], ["altitude"], digit, [digit], [digit], [digit], [digit];
tuneILS = ("tune" | "set"), "I L S", ["receiver" | "frequency" | "to"], digit, digit, digit, "dot", digit, digit;
activateAPPmode = ("activate" | "arm"), ["the"], ("approach" | "I L S"), ["mode"];
readBackAccepted = ("affirmative" | "accepted" | "positive");
readBackRejected = "negative";
correction = "correction";

Meaning of the notation:

rule = chain of text portions (a portion can be another rule or a terminal string), portions are separated by commas
["some text"]: can be spoken or left away
("text a" | "text b"): one-of text portion
"text": terminal string
