60 The following list of frequently asked questions and answers is intended to address topics that are expected to arise when reviewing or using this guidebook. They are developed with the two primary stakeholders in mind: airport operators and air quality regulatory agencies. What is the typical GSE fleet composed of? Answer: The typical GSE fleet varies by airport, aircraft, and weather. GSE fleet varies by aircraft, depending on the contents of the aircraft (i.e., passenger versus. cargo). The size of the aircraft is also considered when assigning a GSE fleet to an aircraft. Larger aircraft will require more powerful equipment. In addition, the use of some GSE are dictated largely by climatic (e.g., deicing vehicles, ground A/C and heating units, etc.). Typical GSE equipment can be found in Chapter 2. What if airport-specific GSE observations cannot be taken to use in AEDT? Answer: If airport-specific observations cannot be taken, the research team has outlined a method for estimating both GSE fleet population and the TIM for each piece of GSE equipment by aircraft size. See Chapter 5 for details. How do GSE emissions differ from other vehicle emissions? Answer: In general terms, the types of emissions generated by conventionally-fueled airport GSE are comparable to those of other types of motorized vehicles and equipment that burn gasoline and diesel as an energy source. See Chapter 2 for more details. What is the difference between on-road and nonroad GSE? Answer: On-road vehicles are vehicles licensed to travel on public roadways including auto- mobiles, vans, trucks, buses, etc. For airport GSE, these are mostly limited to catering and cabin service trucks. Nonroad vehicles are vehicles and equipment not intended to be registered or operated on public roadways. This category broadly includes aircraft, watercraft, locomotives, recreational vehicles, construction vehicles, farm equipment, etc. For airport GSE, this repre- sents the vast majority of vehicles and equipment and comprises baggage tugs, belt loaders, push-back tractors, etc. See Chapter 2 for more details. What are the typical functions of a GSE fleet? Answer: The typical functions are: ⢠Aircraft maintenance and cleaning, including engine and fuselage repairs, waste-water and garbage removal; ⢠Aircraft maneuvering, including moving aircraft out of a gate, to/from maintenance areas, etc.; ⢠Aircraft refueling, including fuel transfer from fuel trucks or fuel hydrant systems; Commonly Asked Questions and Answers
Commonly Asked Questions and Answers 61 ⢠Airfield maintenance, including grass mowers, pesticide applicators, and paint stripers; ⢠Deicing and snow removal, including aircraft deicing vehicles, snow scoops and plows, etc.; ⢠Emergency response, including ARFF vehicles, ambulances, and police cars; ⢠Moving payloads, including loading, unloading, and transporting of passengers, baggage and/ or cargo; and ⢠Restocking of provisions, including food, beverages, potable water, and lavatory chemicals. See ACRP Report 78, Section 3.1.1 for additional details. What are the relevant federal statutes and programs pertaining to GSE? Answer: A summary listing of the primary federal statutes and programs pertaining to the manufacturing, ownership and operation of GSE is presented in Tables 3-3 and 3-4 from ACRP Report 78. Are alternative GSE fuels being considered at airports? Answer: A variety of alternatives fuels are being considered at different airports. See Section 3.4.1 of ACRP Report 78 for more details. Does climate affect the typical GSE assignment? Answer: GSE equipment is dependent on the weather. Cold climates require deicing equip- ment to be utilized, whereas warmer climates may not require the removal of snow and ice. See ACRP Report 78, Table 3-1, for more details. What type of pollutants does GSE equipment emit? Answer: Criteria pollutants and greenhouse gases. See Chapter 2 for more details.
