LAADR Low Altitude Alternate Departure Routes

LAADR is a procedure whereby flight altitudes may be limited to flight level 230 and below. LAADR procedures are primarily used in the departure phase of flight, but can be extended for an entire flight when operational benefits are achieved. This enables more aircraft to transit a specific locale without increasing complexity and congestion at the higher altitudes. MOU's between the specific air route traffic control centers and airline participants must be concluded identifying training requirements and procedures to be implemented. Agreements reached at the local level on LAADR must be briefed to all parties involved (controllers, pilots and dispatchers). Participants greatly benefit from having common situational awareness. Pilots have been briefed not to request higher altitudes when utilizing this procedure. Notification and implementation of LAADR procedures, via the ATCSCC Advisory System, provide dispatchers and system users the ability to accurately plan resources and fuel requirements.
