What does code 1255 indicate?

Code 1255 is associated with firefighting activities. This code is utilized to signify that an aircraft or a specific operation is engaged in aerial firefighting efforts, which can involve both water dropping and other forms of suppression to combat wildfires from the air.

Understanding this code helps air traffic controllers and other aviation personnel coordinate efforts during emergency situations, ensuring that firefighting aircraft receive the necessary airspace privileges and support needed to operate effectively and safely in a potentially hazardous environment. Military transport operations, regular flight operations, and search and rescue missions have their unique codes, and those are not relevant in this context, allowing code 1255 to stand out specifically for firefighting activities.
