Mayor Sheila Young . July 15, 2004 Page 4 of 9 the ILS from Runway 27R to Runway 27L because aircraft would no longer need to perform the sidestep maneuver, and in -trail separations (the distance one aircraft follows another down the ILS flight path) could be reduced. Based on more recent and detailed analyses by the Port and FAA regarding the possibility of an ILS on both Runways 27L and 27R, this statement, although theoretically possible, is generally not correct. Practically speaking, Northern California • ( NORCAL) TRACON treats Runways 27L and 27R at OAK as a single runway for the purposes of lining -up and sequencing aircraft to fly the ILS. The air traffic controllers at NORCAL TRACON line -up and sequence aircraft at the same in- trail distance (3 miles apart) whether the aircraft intends to land straight -in on the ILS for Runway 27R or sidestep to Runway 27L (as required in the Federal Aviation Regulations). Therefore, there is no practical capacity increase associated with relocating the ILS from Runway 27R to Runway 27L due to elimination of the sidestep maneuver. • Moreover, relatively few jet aircraft must sidestep from Runway 27R to Runway 27L for the extra 758 ft. of runway length. The Port believes that most, if not all, business jets are capable of landing on Runway 27R, and that even some commercial jets (e.g., B737s) are capable of landing on Runway 27R, and therefore do not need to sidestep. Even though the aircraft using North Field are capable of landing on Runway 27R, some pilots may elect to perform the sidestep maneuver for an increased margin of safety to minimize potential for an overrun. Please note that the Airfield Study was initiated in response to SFO's airfield plans in order to ensure that Oakland's airspace and future operational needs were considered in conjunction with SFO's needs. Due to the increased • workload at OAK due to the events of September 11, 2001, and the fact that SFO dropped its airfield project, and the completion of RAPC's (Regional Airport Planning Commission) regional planning efforts, the Port did not prepare a final version of its Airfield Planning Study. Therefore, issues addressed in the study were not brought to closure. • 4) Section 12.1.3 states: ...In terms of airfield capacity, relocation of the ILS could provide a slight increase in North Field capacity, because aircraft that now follow the approach to Runway 27R and then sidestep to Runway 27L would not have to follow the sidestep procedure and therefore separations between aircraft may be slightly lower on approach. In response to the point above, please also'explain the Port's definition of capacity as it relates to Federal guidelines and airport service levels. Answer: The Port's definition of capacity is the number of operations (defined as a takeoff or landing) that can occur in a given time period with a certain level of
