Circulation not included. The existing air cargo apron is approximately 26,000 square yards. The apron has a SIDA area that is used for both cargo and passenger charter operations. The apron includes painted markings for up to seven cargo aircraft (such as Cessna Caravans). This is more space than what is required though the planning period based on the forecast of cargo operations. The cargo apron’s Security Identification Display Area (SIDA) currently encompasses the entire cargo apron. Only cargo aircraft must use the SIDA area. Charter aircraft operations are typically not required to operate in a SIDA area. The size of the existing SIDA area demands that all charter and other aircraft parked on the apron be subjected to security screening and SIDA requirements. It is recommended that the SIDA marking be reduced to only the size needed by cargo aircraft. Charter Operations As mentioned, Lawrence Air Service operates out of the cargo facility. This FBO receives large charter operations and large general aviation and military aircraft that are too large to be served by Atlantic Aviation. These operations require a different type of analysis of the cargo facility to determine if the facility is adequate for the FBO’s operations, and if the facility is adequate for those operations combined with cargo operations. The cargo apron can accommodate very large and heavy aircraft. The apron is rated for 550,000 pound dual-tandem gear aircraft, which is more than adequate for a Boeing 747 (ADG V/TDG 5). The limiting factor for the apron is Taxiway A, L, and J, which are designed to ADG III/TDG 5 standards. Even though the taxiway meets TDG 5 standards of 75 feet in width, the fillet geometry is such that wide body aircraft are not easily accommodated. For example, the Boeing 747 is a TDG 5 aircraft, but turning from Taxiway A into the cargo ramp with cockpit over centerline steering is not feasible without a high chance of the main gear running off the pavement. Therefore, these aircraft are typically parked on the heavy pads north of the terminal. Boeing 737 aircraft are fully accommodated and can power in and out of the ramp easily. Boeing 757 and 767 variants can be accommodated as well. It is recommended that Taxiway L and J be expanded to allow easy access for TDG 4 and 5 aircraft. Serving large charter operations on the cargo apron impacts landside facilities, specifically vehicle parking. Charter operations can overwhelm the small vehicle parking lot at the cargo facility, which only has 22 EUGENE AIRPORT MASTER PLAN 3-61
