Per the request of MSP aviation, the following announcement will be used when Medivac is landing in our jurisdiction:
Upon final approach of a helicopter, the incoming aircraft will advise Communications of their “final approach”. Communications will sound a one (1) second alert tone on the operational talk group to cease all radio traffic until the helicopter has landed.
Example: “Washington to all units and incident command, Trooper 3 in on final approach, maintain radio silence unless you have an emergency”
The unit assigned to the landing zone (LZ) will advise Communications when the aircraft has safely landed. Communications will make an announcement over the operational talkgroup that radio traffic may resume normal operations.
Example: “Washington to all units, Trooper 5 has landed, resume normal operations”
