The first step in the process of managing threats is threat identification. As an example, a
meteorological office that provides regular weather forecasts already constitutes a way to understand bad weather as a threat. Likewise, a controller may ask aircraft about wind (direction and speed) at a certain altitude or level, to be able to provide more accurate radar vectors.
A further step is to share real-time information about the existence of threats with other
controllers. To use an example of "aircraft performance", when observing the climb performance of a B747 with a destination relatively close to the departure airport the tower controller could alert the departure controller to the fact that the B747 is climbing faster than average. Passing information about differing wind speeds and directions at different altitudes from one controller to the next is another example of sharing knowledge about threats.
In the case of "environment" being a threat, managing it can be made easier for controllers if
the high terrain or obstacles are depicted on the radar map. This applies as well for residential areas that must be avoided for noise abatement purposes below certain altitudes or during certain hours. If these areas can be presented on the radar map when necessary, controllers will be able to manage the threat more adequately. ICAO
