Abstract: : The safety and reliability of the fire-fighting water supply system in aerodrome depends on the correct selection of the fire-fighting water consumption which shall be the first consideration for designers. It is completely feasible to use "maximum aircraft type method" to determine the fire-fighting water consumption and check by using the calculation method of water supplement quantity of Airport Rescue and Fire Fighting(ARFF) vehicles, so as to obtain the experience value of the fire-fighting water consumption of the typical aircraft in aerodrome under the corresponding airport category for RFF. The revised empirical value is close to the published value of NFPA 403-2018, and consistent with the actual operation of the new airport in Hong Kong. It is of great significance to guide the design and construction of fire-fighting water supply system in aerodrome and the allocation of ARFF vehicles. It is recommended that the national civil aviation authority should promptly revise (MH/T 7015-2007) and (MH/T 7002-2006) to meet the needs of engineering construction and ensure the safety and reliability of the ARFF.
