Description<br />
In<strong>for</strong>m of winter conditions when it occurs or <strong>for</strong>ecasted. In case relevant parameters are not<br />
adjusted to these winter conditions, all relevant partner should be in<strong>for</strong>med, and <strong>CDM</strong><br />
plat<strong>for</strong>m and planning parameters updated to default winter condition values.<br />

Process<br />
Winter condition or <strong>for</strong>ecast is recorded in the <strong>Airport</strong> <strong>CDM</strong> plat<strong>for</strong>m after triggering by a<br />
meteorological report or manual input. At the time of <strong>for</strong>ecast or current time + tolerance a<br />
check is made to detect if the parameters <strong>for</strong> winter conditions have been adjusted.<br />
Output<br />
When the process is triggered a message is sent to all relevant partners to in<strong>for</strong>m them on<br />
the winter conditions. After the reaction period a check is made to determine if planning<br />
parameters have been adjusted.<br />
Response to Messages<br />
All partners to increase planning parameter values based on statistical and operational<br />
experience during similar winter conditions; or to decide and in<strong>for</strong>m the <strong>CDM</strong> plat<strong>for</strong>m to<br />
ignore the alert message, and insert a clarification <strong>for</strong> the action.<br />
Consequences of No Action following Alert Messages<br />
Default parameters <strong>for</strong> winter conditions must be set, and the partners should be in<strong>for</strong>med.<br />
