STCA, MTCA, MSAW, DAIW, RAM, CLAM, SAR, MPR, ETO
STCA: Short Term Conflict Alert
It is displayed when a minimum separation distance between a pair of surveillance tracks is, or is predicted to be
violated within a short look ahead time typically 2 minutes.
MTCA: Medium Term Conflict Alert
It is displayed when a potential conflict between AC exists within a 20 minute look-ahead time period, based on
current trajectory information.
MSAW: Minimum Safe Altitude Warning
Displayed when an AC is nearing the minimum safe altitude.
DAIW: Danger Area Infringement Warning
Entry into dangerous airspace. In vatSys can include restricted areas such as R124?
RAM: Route Adherence Monitoring
It is displayed when the AC is out of the 5-5 NM (fixed value and no settings so far) range of the route calculated by EuroScope. Here are also some exceptions:
* RAM is not displayed on the ground.
* RAM is not displayed if the AC is cleared for approach.
* RAM is not displayed when a direct is set or has assigned heading.
CLAM: Cleared Route Adherence Monitoring
It indicates that the pilot does not follow the cleared level. It is shown if the plane is outside the +-300 ft range of his temporary or final altitude and his vertical speed does not indicate that he is trying to reach it. There are some exceptions:
* CLAM is not displayed on the ground.
* CLAM is not displayed if the AC is cleared for approach.
* CLAM is not displayed if no temporary altitude set and the plane is not tracked.
* CLAM is not displayed if AC is flying at final altitude but cleared for lower.
SAR: Search and Rescue
MPR: Missed Position Report
ETO: Estimated Time Over significant point
--
APW: Area Proximity Warning
Entry into Forbidden airspace
LBW: Level Bust Alert
Altitude deviation from CFL. See RAM / CLAM?
NCW: Non-Conformance Warning
Deviation from the flight plan. See RAM / CLAM?
--
PRL: Pilot reported level
ATD: Departure time
