The following policies apply to all operations.
3c.1.1 Language Usage. All ATC must be proficient in the English language. All communication initiated in English must elicit a response in English. ATC must not assume that a POSCON Member (pilot or ATC) knows the local Division language. Local languages may be used so long as both the communicator and the receiver mutually agree to such exchanges.
3c.1.2 Working Microphone. A working microphone is required and all controllers must be prepared to talk on frequency at all times.
3c.1.3 Monitoring Guard. Controllers shall monitor Guard (121.500 MHz) at all times. If this Guard is not set up in the VSCS panel, consult with the Division Facility Data Specialist. Controllers shall only use Guard frequency to attempt to contact an unresponsive pilot and get that pilot to the correct frequency. Conversations, animal noises, or any other unrelated chatter is strictly prohibited on Guard.
3c.1.4 Unnecessary Communication. Keep unnecessary chatter on active control frequencies and landlines to a minimum. Any form of trolling on any communication method is strictly prohibited. In this context trolling is defined as screaming, intentionally blocking transmissions, playing music, pretending to be another aircraft or ATC, intentionally leaving your mic open, or anything else deemed as overly disruptive.
3c.1.5 Phraseology. Controllers must follow the phraseology standards outlined in 3g.2.2. That means controllers should make every effort to keep all communications as standard as possible. Controller should avoid "shortcutting" or being lazy with phraseology.
