The aircraft that will be parked at the Delivery Center will not be occupied by a full compliment of passengers as is typically found at an aircraft terminal. The occupancy of the aircraft at the Delivery Center is limited only to Boeing personnel and the customer representatives including the pilots needed during the aircraft delivery process. With a significantly smaller number of persons occupying the aircraft during the aircraft delivery process as compared to the number disembarking an aircraft at a terminal, the issue of interfering with the egress of a potentially large group of persons would not be expected in this application. 3. The probability of a spilled aircraft fuel fire at a terminal building or terminal complex is extremely low, as evidenced by the vast number of aircraft that are parked at terminal gates and routinely fueled on a daily basis, nearly without incident. As remote as this probability is, the exposure to life and property is such that proper precautions are warranted. The probability of such an event is increased during the aircraft fueling process. Spill events are more likely to occur during the fuel transfer process, than when an aircraft is parked in a static condition and no fuel transfer is occurring. The business plan for the Delivery Center does not include fueling operations while the aircraft is parked in the Delivery Center positions, thus eliminating the probability of a fuel spill while fuel transfer operations are in progress. Furthermore, the Boeing aircraft manufacturing process involves fuel system pressurization and extensive fuel system leak checks prior to delivery that would render the probability of an aircraft fuel leak while parked at a Delivery Center position practically zero. 4. A positive factor regarding the choice of aircraft loading walkways constructed of steel and glass elements is that the manufacturer (ThyssenKrupp) submitted their product to a listed NRTL independent laboratory where it was subjected to fire testing using the methods are parameters outlined in Chapter 6 of NFPA 415. The submitted assembly passed these fire tests resulting in an equivalent fire resistance rating as the aircraft loading walkways that are of all steel construction. The results of this testing is included with this submittal. 5. These aircraft loading walkways constructed of steel and glass elements have been installed and are currently in use at actual terminal building locations within the U.S. and Canada. Those that have been manufactured by ThyssenKrupp and thus have undergone NFPA 415 fire testing referenced in item 4 above have been installed at the airports in Killeen, TX; Amarillo, TX and Vancouver, BC Canada. 6. Building doors have been installed with access from the second floor of the Delivery Center, will lead to the aircraft loading walkways. Currently, there are no plans for these doors to be propped in the open position. Should future operating plans change and the desire of The Boeing Company is to prop these doors open, magnetic hold open devices actuated by area smoke detectors could be installed at that time. � l
