Tower

1. separate air traffic controller is responsible for the sequencing and spacing of arriving aircraft to both runways
   
2. the final approach course or track is intercepted by use of:
   1. vectoring; or
   2. a published arrival and approach procedure that intercepts with the IAF or the IF.
      
3. the instrument flight procedure that aligns the aircraft with the extended runway centre line is a precision approach 
4. aircraft are advised that approaches are in use to both runways;
5. a minimum of nominal 1000 ft vertical separation or a minimum of 3.0 NM horizontal separation is provided between aircraft until established on the final approach courses or tracks of parallel approaches
6. the minimum horizontal separation to be provided between aircraft established on the same final approach course or track is 3.0 NM unless increased longitudinal separation is required due to wake turbulence;
7. the minimum horizontal separation to be provided diagonally between successive aircraft on adjacent final approach courses or tracks is:

The main responsibility of Berlin Tower is to monitor the approach area between 14 NM and the threshold. In case of any deviation from the LOC, the traffic on the adjacent LOC shall be turned immediately!

"Turn left/right(number) degrees/heading(three figures) immediately to avoid traffic *deviating from adjacent approach*, climb(level)."

In order to perform independent parallel approaches, both director and tower positions have to be staffed.

During Independent Parallel Approaches, both Tower need to activate the NTZ between both runways. 

SUSPENSION OF INDEPENDENT PARALLEL OPERATIONS DUE TO METEOROLOGICAL CONDITIONS:

The meteorological conditions to be considered include, but are not limited to, the following:

1. wind shear;
2. turbulence;
3. downdrafts; and
4. crosswind and significant meteorological conditions such as thunderstorms, which might otherwise increase deviations from the final approach course or track to the extent that safety may be impaired.

1. Parallel runways may be used for independent instrument departures as follows:
   
   1. both runways are used exclusively for departures (independent departures) or
   2. one runway is used exclusively for departures while the other runway is used for a mixture of arrivals and departures (semi-mixed operation) or
   3.  both runways are used for mixed arrivals and departures (mixed operation).
      
   4. Independent IFR departures should only be conducted from parallel runways when the conditions listed below are met:
      1. both aircraft are flying an RNAV or RNP instrument departure and
      2. the turn commences no more than 2.0 NM from the departure end of the runway
      3. a suitable ATS surveillance system capable of identification of the aircraft within 1.9 km (1.0 NM) from the end of the runway is available
      4. ATS operational procedures ensure that the required track divergence is achieved.

In case departing traffic deviates from the departure route, the responsible tower controller needs to create separation immediately. 

Note: Vectored and visual departures are not approved for independent parallel departures

Segregated parallel operations should only be conducted on parallel runways when the following conditions are met:

1. the nominal departure track diverges immediately after take-off by at least 30 degrees from the missed approach track of the adjacent approach
2. the instrument flight procedure that aligns the aircraft with the extended runway centre line is one of the following
   1. precision approaches or RNP approach
      
   2. visual approach
