EXECUTIVE SUMMARY

Title: Norman Y. Mineta San Jose International (SJC) Airport Replacement Airport Traffic Control Tower AFTIL-2 – No Hazards

Initiating Organization: SJC/AJW-244

Safety Analysis Type: Operations (OPS)

Norman Y. Mineta San Jose International Airport (SJC) is located in Silicon Valley, about two miles northwest of San Jose, CA. San Jose International Airport is a self-supporting enterprise owned and operated by the city of San Jose. SJC has two parallel runways, 12L/30R and 12R/30L (11000 x 150 ft.). The SJC ATCT is a Level 7, Non- Standard type design, Federal Aviation Administration (FAA) owned, operated, and maintained Tower with Radar facility commissioned in 1994. The ATCT cab area is approximately 365 sq. ft. and the facility operates from 0600Z -2400Z local. SJC proposes to assess two viable sites and determine physical characteristics for a potential replacement ATCT.

An Airway Facilities Tower Integration Laboratory (AFTIL) 1 meeting was held July 9 and 10, 2019 in Atlantic City, NJ. Meeting attendees participated in siting activities for the proposed replacement SJC ATCT and conducted an SRM Panel to generate a Comparative Safety Assessment (CSA) of two viable ATCT sites (Site 1, Site 4).

An AFTIL-2 meeting was held, October 19 and October 20, 2021, to assess the two viable sites, Site 1 and Site 4, to determine physical characteristics for a potential replacement SJC ATCT. Panel member representatives from the FAA SJC ATCT and AFTIL personnel attended the meeting on-site at the William J Hughes Technical Center (WJHTC) Building 170 lab. Remaining members attended the meeting virtually via Zoom (Section 5). During the meeting, cab orientation (direction of view), stairwell location, column/mullion placement, and control position location for each site were determined. An Air Traffic Organization (ATO) Safety Risk Management Panel (SRM) Panel was convened to conduct a safety analysis for each site generating an AFTIL-2 Comparative Safety Assessment.

The Safety Risk Management (SRM) Panel met to conduct a viable sites safety analysis as a proposed National Airspace System (NAS) change based on the Air Traffic Organization (ATO) SRM process as defined by the ATO Safety Management System (SMS) Manual, dated April 2019. The SRM Panel, comprised of stakeholders in the change, were organized by the AFTIL with support from the Western Service Area (WSA) and Quality Control Group (QCG). Stakeholders, which included representatives of FAA WSA, SJC ATCT and San Jose Airport Administration, participated in the ATCT siting activities.

No Hazards were found in either of the two viable sites.

SECTION 1. CURRENT SYSTEM

Norman Y. Mineta San Jose International Airport (SJC) is located in Silicon Valley, about two miles northwest of San Jose, CA. San Jose International Airport is a self-supporting enterprise owned and operated by the city of San Jose. SJC is the San

Francisco Bay Area's second-busiest airport by passenger boardings, behind San

Francisco International Airport. The Airport Master Plan projects demand of 22.5 million annual passengers and 184,000 commercial airline operations by the year 20371 necessitating improvements in taxiway system improvements capable of serving wide-body commercial aircraft, new and remodeled terminal buildings to adequately serve projected demand and new or expanded cargo and general aviation facilities. The airport is also an official U.S. Customs and Border Protection international port of entry.

SJC has two parallel runways, 12L/30R and 12R/30L (11000 x 150 ft.) with five partial to almost full length taxiways. Centerline separation between the parallel runways is approximately 700 ft. The current parallel TWY V is planned to be converted to ramp area with TWY W1 renamed TWY V. The SJC ATCT is a Level 7, Non-

Standard type design, Federal Aviation Administration (FAA) owned, operated, and maintained Tower with Radar facility commissioned in 1994. The ATCT cab area is approximately 365 sq. ft. and the facility operates from 0600Z -2400Z local. SJC ATCT airport operations, during 2019, totaled over 205,000 with over 72% attributed to Air

Carrier. Due to the Covid pandemic (2020), total airport operations dropped to a little over 115,000 with air carrier reduced to a little over 62% of these operations. During the first eight months of 2021, SJC has shown an increase in airport operations moving towards 2019 numbers.

The existing ATCT cab is equipped for the following positions:

Local Control (LC)

Local Assist (LA) (acts as a second pair of eyes)

Ground Control (GC)

Ground Control West (GCW) (optional on a southeast flow)

Clearance Delivery/Flight Data (CD/FD)

Front Line Manager/ Controller-In-Charge (FLM/CIC)

Need for an SRM Panel The need for a Safety Risk Management (SRM) panel is necessary to relocate the existing SJC ATCT. When the existing ATCT was commissioned, the longest runway was 8,000 ft. In a Comparative Safety Assessment, held July 9 and 10, 2019, SJC ATC found line of sight (LOS) issues: at night and even during some daylight conditions that it is hard to see the approach ends of the runways with the extension of a set of parallel runways to 11,000 ft. At the existing eye level height and location of the ATCT, a

Airport Master Plan for Norman Y. Mineta San Jose International Airport As Amended Through April 2020

Visibility Siting Requirements Human Factors Analyses found the SJC ATCT failed the LOS Angle of Incidence requirement, minimum .8 degrees, with a value of .74 degrees for key point2 RWY 30L (Tower to Key Point Distance: 5282 ft.) (Figure 1) and .72 degrees for key point RWY 30R (Tower to Key Point Distance: 5471 ft.) (Figure 2).

Lookdown issues with the ramp adjacent to the ATCT and TWY V were also found.

Airport expansion and restructuring may introduce new, or enhance existing, LOS issues.

Scope of SRM Panel An Airway Facilities Tower Integration Laboratory (AFTIL) 1 meeting was held July 9 and 10, 2019 in Atlantic City, NJ. Meeting attendees participated in siting activities for the proposed replacement SJC ATCT and conducted an SRM Panel to generate a Comparative Safety Assessment (CSA). Two sites were initially assessed as viable and preferred, Site 1 and Site 4).

An AFTIL-2 meeting was held, October 19 and October 20, 2021, to assess the two preferred sites, Site 1 and Site 4, to determine physical characteristics for a potential replacement SJC ATCT. Panel member representatives from the FAA SJC ATCT and AFTIL personnel attended the meeting on-site at the William J Hughes Technical Center (WJHTC) Building 170 lab. Remaining members attended the meeting virtually via Zoom (Section 5). During the meeting, cab orientation (direction of view), stairwell location, column/mullion placement, and control position location for each site were determined. An Air Traffic Organization (ATO) Safety Risk Management Panel (SRM) Panel was convened to conduct a safety analysis for each site generating an AFTIL-2 Comparative Safety Assessment. Meeting attendees applied the Air Traffic Organization (ATO) SRM process as defined by the ATO Safety Management System (SMS) Manual, dated April 2019.

SECTION 2. DESCRIPTION OF CHANGE

Existing LOS issues with portions of key movement areas of the airport and future airport expansion/restructuring present a possible safety risk to the ATC environment.

An AFTIL-2 meeting was held, October 19 and October 20, 2021 to determine a potential replacement SJC ATCT.

Two sites were assessed as preferred: Site 1 and Site 4

Site 1: Latitude: 37 21’ 35.09" North, Longitude: 121 55' 58.20" West;

Eye Level AGL 153 feet.

Site 4: Latitude: 37 21' 34.23" North, Longitude: 121 55' 58.85" West;

Eye Level AGL 155 feet.

Figures 4 & 5 represent an overhead depiction of the two SJC preferred sites that were determined as viable locations. The SJC Future Airport Layout Plan Update dated

October 2018 (Figure 6), depicts the existing and future airport layouts.

The SRM Panel attendees agreed that operations in any of the replacement ATCTs will not introduce risk into the NAS.

SECTION 3. RATIONALE FOR A SAFETY FINDING WITHOUT HAZARDS

SRM Panel attendees conducted a safety analysis on the SJC replacement ATCT Site 1 and Site 4, based on the PHL designated for use during AFTIL-2 SRM Panel assessments, which reviews Interior and exterior physical barriers. The AFTIL 2 Safety Assessment encompasses analysis and assessment of orientation of ATCT cab to field, control positions, equipment, mullions and stairwell location for overall optimal visibility of the field. The following tables list SRM Panel attendee comments, observations, and findings for each preferred site according to PHL section topics. SRM Panel attendees agreed that operations in any of the replacement ATCTs will not introduce risk into the NAS for both existing and proposed structures depicted in the SJC Future Airport Layout Plan Update dated October 2018. SJC ATC selected Site 4 as their recommended site.

16. Interior physical barriers

16 a. Position of ATC in Tower Cab:

Facing (Priority) North---East-- -West---South

SJC ATC oriented the cab (12 sided structure supported by mullions) north east (Figure 8), similar to the existing ATCT (8 sided structure). LC position is located to the left of a mullion facing north east with a line drawn perpendicular to the parallel runways. LA position is located to the right of this mullion. GC and CD/FD positions are located to the right of LA, each separated by one pane of glass respectively. GCW position is located to the left of LC separated by one pane of glass. The FLM/CIC position was relocated from left of GCW to a cab center console desk, facing LC position. The stairwell is located on the south side of the cab with the entrance just to the right and rear of the FLM/CIC desk. Cab orientation and control position locations were examined and determined for optimal visibility of the airport by SJC ATCT personnel. Sunstreams, for different times of the year, were displayed to depict possible effects of the sun. To mitigate the hazards determined in the AFTIL 1 Safety Assessment (Controller loss of situational awareness associated with sun angle), SJC ATC requested "Double Shades" be made available as a requirement. SJC ATC found no major issues with mullion placement and determined any issues would be easily resolved by moving to look around the mullion.

Findings: No Hazards

From LC (LA)

LC position faces northeast towards the main Air Carrier terminal across the field, with the approach ends of RWYs 30L/30R to the right of view and the approach ends of RWYs 12R/12L to the left of view.

LA position is just to the right of LC position and acts as an "extra pair of eyes" and coordinator for LC. At the proposed location and height (eye level 153 ft.), SJC ATC had an unobstructed view of all runways, their exit/entrance points, approach ends, arrival and departure paths. SJC handles Medevac helicopter traffic from the Valley Medical Center (located a few miles south of the field) and the Regional Medical Center (a few miles northeast of the field). Good views were found for each. SJC ATC, positioned the mullions so as to provide overall optimal visibility for each control position.

From LC position, SJC ATC personnel were concerned with a mullion positioning just to the left of CD/FD which interfered with an open view of the approach end to RWY 30R and line up and wait spots for RWY 30L at TWY D and C. SJC ATC acknowledged mullions are not considered an obstruction. The cab model was rotated 15 degrees counter clockwise to diminish this issue. Control positions remained in their original locations relative to cab orientation. SJC ATC found this mullion positioning depicted a clear view of these concerned areas. SJC ATC found no major issues with the remaining mullion placements and determined any issues would be easily resolved by moving to look around the mullion.

Findings: No Hazards

From GC (GCW)

GC position faces east southeast to the right of LA position separated by one pane of glass. GC is the primary control position with the option to open a same equipped GCW position located on the northwest side of the cab. GC primarily faces the approach ends RWYs 30R/30L. Site 1 provides a more distinctive and clearer view of TWYs Z and Y, which are located across the field, than from their existing ATCT. Site 1 also provides a view of gates 1-3 of Terminal 1 across the field. The location of Site 1 created lookdown issues with a portion of TWY V, in front of Site 1, Signature ramp, to the northwest of Site 1, and Atlantic ramp, to the southeast of Site 1. Although ramp areas are considered non-movement and not under control of ATC, SJC ATC found a concern with whether aircraft, from these areas, were actually holding short of TWY V when they called for taxi. Airport restructuring plans include converting TWY V to a ramp area, renaming TWY W1 (just to northeast and parallel to TWY V) as TWY V prior to commissioning of a new ATCT. This would resolve the LOS issue with TWY V and help in alleviating any concern with the ramp areas. SJC ATC found a clear view of all other taxiways and most ramp areas.

Findings: No Hazards

16 b. Position of Tower Cab equipment

A physical layout of the 550 square foot ATCT cab with typical equipment was provided.SJC ATC reviewed and realigned equipment for overall optimal locations. Future upgraded equipment was discussed. The design and size of the cab would allow for any additional or upgraded equipment.

Findings: No Hazards

16 c. Position of Tower Cab mullions

Reviewed in Section 16a.

Findings: No Hazards

17. Exterior physical barriers 17a. Construction equipment ( Vehicles, Cranes, scaffolding etc.)

SJC ATC found no LOS issues with proposed airport expansion, construction or equipment associated, as depicted on the SJC Future Airport Layout Plan Update dated October 2018. Any impact to Air Traffic operations would be coordinated well prior with SJC ATC.

17c. Existing ATCT

Working in Existing ATCT with Construction of Site1 in progress

Construction of Site 1 was examined for LOS issues while working in the current ATCT (Figure 11). Site 1 is located approximately 130 ft. (center to center of cab) west of the current ATCT. The eye level height of the existing ATCT is 83 ft. AGL. The top of tower (TOT) height of Site 1 is projected to be 183

ft. AGL.SJC ATC found a LOS issue with construction of Site 1 from the perspective of the existing ATCT. A portion of the downwind to RWY 12R/30L was blocked. A major portion of their traffic is straight in. A very small portion of small VFR traffic would be affected by this blockage. Due to the amount of time of blockage (a few seconds), the amount of traffic affected and additional procedures to mitigate this blockage, they considered this a minor issue of concern. SJC ATC determined controller awareness and pre duty familiarization would further resolve this to an area of low concern. No other issues were determined.

Findings: No Hazards

Working in Site 1 with existing ATCT still in place

Working from Site 1 with the existing ATCT in view was examined (Figure 12). Only the very top of the existing cab is in view, with blockage of a small portion of TWY W1 and the existing TWY V. Due to the small portion and time of blockage, SJC ATC found no LOS issues.

18. Other No other issues were found with Site 1

16 a. Position of ATC in Tower Cab:

Facing (Priority) (North---East-- -West---South) Northeast

SJC ATC oriented the cab (12 sided structure supported by mullions) north east (Figure 16), similar to the existing ATCT (8 sided structure). LC position is located to the left of a mullion facing north east with a line drawn perpendicular to the parallel runways. LA position is located to the right of this mullion. GC and CD/FD positions are located to the right of LA, each separated by one pane of glass respectively. GCW position is located to the left of LC separated by one pane of glass. The FLM/CIC position was relocated from left of GCW to a cab center console desk, facing LC position. The stairwell is located on the south side of the cab with the entrance just to the right and rear of the FLM/CIC desk. Cab orientation and control position locations were examined and determined for optimal visibility of the airport by SJC ATCT personnel.

SJC ATC found no major issues with the remaining mullion placements and determined any issues would be easily resolved by moving to look around the mullion. SJC ATC preferred Site 4 as the recommended site. Location, further southwest from the movement and ramp area, and height of Site 4 provided a wider peripheral view of the approach ends of the runways, approach and departure paths with less rotation and movement within the tower cab.Findings: No Hazards

From GC (GCW)

GC position faces east southeast to the right of LA position separated by one pane of glass. GC is the primary control position with the option to open a same equipped GCW position located on the northwest side of the cab. GC primarily faces the approach ends RWYs 30R/30L. Site 4 provides a an even more distinctive and clearer view, than Site 1, of TWYs Z and Y, which are located across the field. Site 4 also provides a better view of the backside of Terminal 1, across the field, of gates 1-

3. Site 4 provides a very good view of the entry/exit point to the movement area of the newly constructed ARFF station and the soon to be phased in run up pad for RWY 30L. The lookdown issues, created by Site 1, with a portion of TWY V and their concerns with whether aircraft, from these areas, were actually holding short of TWY V when they called for taxi were resolved. In addition, airport restructuring plans include converting TWY V to a ramp area, renaming TWY W1 (just to northeast and parallel to TWY V) as TWY V prior to commissioning of a new ATCT. All entry/exit points were visible. A majority of the Signature and Atlantic ramps were also visible. As with LC position, SJC ATC preferred Site 4 as the recommended site for GC position. Location, further southwest from the movement and ramp area, and height of Site 4 provided a wider peripheral view of the taxiways and ramp areas with less rotation and movement within the tower cab.

Findings: No Hazards

17c. Existing ATCT

Working in Existing ATCT with Construction of Site 4 in progress

Construction of Site 4 was examined for LOS issues while working in the current ATCT (Figure 19). Site 4 is located approximately 400 ft. (center to center of cab) west of the current ATCT. The eye level height of the existing ATCT is 83 ft. AGL. The top of tower (TOT) height of Site 4 is projected to be 185

ft. AGL. SJC ATC found a LOS issue with construction of Site 4 from the perspective of the existing ATCT. A portion of the downwind to RWY 12R/30L was blocked.
