Air Traffic Control

Stations and Cities provide Air Traffic Control. They call on the Hail channel when you enter their sensor coverage area, depart it, or transition from their area to someone else's, similar to real air traffic control.

They will also now warn off enemy spacecraft that enter their coverage area. This includes pirates so your own cities and stations should call them out.

Below is a list of messages that are sent by the Air Traffic Control and what they mean.

Sensor contact. No radar services available. Maintain VFR.

You have entered the sensor range of a friendly city or station. They are not providing traffic separation services, i.e. not calling out other traffic. You are to operate under visual flight rules, which means you have to see where you are going, i.e. remain clear of clouds.

Sensor contact lost. Proceed VFR. Have a good flight.
You have departed the sensor range of a friendly city or station.

You are departing my airspace. Handing you off to Hazeron control.
You have transitioned from the sensor range of a friendly city or station into the sensor range of a different friendly city or station.

Sensor contact. Malacon ADIZ incursion! Leave this area immediately or you will be destroyed.
You have entered the sensor range of an enemy city or station. An ADIZ is an Air Defense Identification Zone.

You are clear of our space. Remain outside the ADIZ or be destroyed.
You have departed the sensor range of an enemy city or station.

You are entering the Malacon Bartertown ADIZ. Prepare to be destroyed.
You have transitioned from the sensor range of one enemy city or station to the sensor range of a different enemy city or station.

ADIZ

ADIZ is short for "Air Defense Identification Zone", which correspond to the sensor coverage areas of all cities and stations.

If a spacecraft enters an enemy ADIZ the detecting city or station will broadcast warning messages about trespassing and instructing it to leave.

Pirates will not engage vessels that are inside any ADIZ.
