Final answer:
NOTAM conditions that affect military operations must be specifically designated and communicated to the relevant civilian air traffic control or civil authorities to ensure safety and efficiency in the shared airspace.
Step-by-step explanation:
NOTAM (Notice to Airmen) conditions that affect only military users, such as Optical Landing System (OLS) outages, drag chute operations, Liquid Oxygen (LOX) availability, etc., should be specifically designated and coordinated with the civilian air traffic control (ATC) or appropriate civil authorities.
It's important for military operations to communicate these conditions because they could affect the airspace management and the safety of both military and civilian aircraft operations. Proper coordination ensures that the relevant civilian authorities are aware of the unique activities that might occur within the airspace.
This communication is typically handled through established protocols and chains of command to ensure that there is a clear understanding of the conditions between military and civilian airspace users. The aim is to avoid disruptions and maintain operational safety and efficiency for all users of the airspace.
For example, if there is an OLS outage at a joint-use airfield, this would need to be communicated to civilian ATC so that any civilian aircraft could be informed about potential changes in the approach and landing procedures that rely on these systems.
The same holds true for unique military operations like drag chute deployments or specific fueling requirements such as LOX, which are not typically used by civilian aircraft but may affect shared resources or airfield operations.
