Where must aircraft fueling ramps be sloped?

Aircraft fueling ramps must be sloped away from terminals to ensure safety and mitigate the risk of fuel spills or leaks that could impact passengers and facility operations. By directing potential spills away from terminal areas, the design helps contain hazardous materials and prevents them from reaching critical infrastructure where people gather. This slope is also essential for effective drainage, ensuring that any fuel or contaminants may flow away from sensitive areas, reducing the chance of ignition or exposure.

The design and layout of fueling ramps are a vital part of an airport's overall safety plan. They not only aim to protect human life but also to safeguard the airport's operations and the environment. In contrast, other slope directions, such as toward terminals, into the runway, or parallel to taxiways, would create undue risks, potentially leading to hazardous situations or ineffective drainage, thus undermining the operational safety of the airport.
