There are some pretty large changes that have come to the way the Nassau FIR and Miami Oceanic airspace operates. Nassau FIR has expanded their coverage across the Bahamian islands to include all the way down to the Turks and Caicos. When Miami Oceanic is offline, they now also provide service to the entire Miami Oceanic airspace. The airspace of Nassau FIR and Miami Oceanic has been split into three primary sectors. Nassau FIR Sector, Provo Sector, and Miami Oceanic Sector. These changes have been made to be able to provide better Air Traffic Control coverage to aircraft across the Bahamian island chain. Due to limitations of some clients that display controllers online, it may not depict correctly to what position is staffing what part of the airspace.

 

A quick summary of the operation of the airspace is below:

If Miami Oceanic is online, and Nassau Center is offline, then Miami Oceanic will control all airspace within the lateral boundaries of the Oceanic Sector, the Provo Sector and the Nassau Sector from FL180 to FL600 only.
 
If Miami Oceanic is online, and Nassau Center is online, then Miami Oceanic will control all airspace within the lateral boundaries of the Oceanic Sector and the Provo sector from FL180-FL600 only.
 
If Miami Oceanic is offline, and Nassau Center is online, then Nassau Center will control all airspace within the lateral boundaries of the Oceanic Sector, the Provo Sector, and the Nassau Sector from SFC-FL600.

 

The Letter of Agreement


 

Nassau FIR Nassau Sector

The Letter of Agreement
The Nassau Sector is the airspace under the authority and operation of Nassau FIR of the
Caribbean Division. Within the lateral boundaries of the Nassau Sector, the vertical boundaries are from the Surface to FL600. If Nassau Center is offline, this airspace shall be controlled by Miami Oceanic from FL180 to FL600 when a Miami Oceanic controller is online. When a Nassau FIR controller becomes available and is online, the airspace within the lateral boundaries of the Nassau Sector will be controlled from the Surface to FL600 by the Nassau FIR.
 
The Simple Version
Nassau FIR now has operational authority and control of all airspace within the lateral boundaries of their airspace at all times. When Nassau Center (MYNN_CTR) is offline, the airspace within the lateral boundaries may be controlled by Miami Oceanic from FL180 to FL600. This is to allow continuity of service to pilots who are transiting the Caribbean.
 
 

Nassau FIR Provo Sector

The Letter of Agreement
The Provo Sector is a portion of the Miami Oceanic Airspace that includes the Providenciales Approach Control. The jurisdiction of this airspace is shared between the Nassau FIR and the Miami ARTCC. Nassau Center is responsible for the airspace from the Surface to FL180 within the lateral boundaries of the Provo Sector. Miami ARTCC is responsible for the airspace from FL180 to FL600. If Miami Oceanic is offline, Nassau Center may control the airspace that is delegated to the Miami ARTCC within the lateral boundaries of the Provo Sector from FL180 to FL600 in addition to the airspace that is delegated to the Nassau FIR until such time that a Miami Oceanic controller is online. Any time that a Miami Oceanic Controller becomes available and is online the airspace within the lateral boundaries of the Provo Sector from FL180 to FL600 will be controlled by Miami Oceanic and the airspace within the lateral boundaries of the Provo Sector
from the Surface to FL180 will be controlled by the Nassau FIR.
 
The Simple Version
Nassau FIR and VATUSA/Miami ARTCC have agreed upon an arrangement that allows Nassau FIR controllers to provide continued service to aircraft that are island hopping around the eastern Bahamian island chain, and those aircraft enroute to the Turks and Caicos or points beyond.
 
When Miami Oceanic (ZMO_CTR) is not online, Nassau Center (MYNN_CTR) will be providing control to aircraft from SFC-FL600 in the Provo Sector AND the Miami Oceanic Sector.
 
When Miami Oceanic is online, Nassau Center (MYNN_CTR) will only provide control within the lateral boundaries of the Provo sector from SFC-FL180 and SFC-FL600 in the Nassau FIR Nassau sector.
 
Please be aware, due to limitations of some of the who’s online clients, it may only show the Nassau FIR Nassau Sector as being “online”, but they also do control the additional airspace as described above that may not appear to be online.

The Miami Oceanic Sector is the airspace under the authority and operation the Miami ARTCC of the United States Division.

If Miami Oceanic is offline, this airspace may be controlled by Nassau FIR controllers until such time that a Miami Oceanic Controller is online and available at which time full operational control will be transferred to the Miami Oceanic controller.
