flapper valves.
Explanation:
According to my research on Aircraft Fuel Tanks, I can say that based on the information provided within the question many fuel tanks incorporate flapper valves. Like mentioned in the question these are implemented to prevent fuel from flowing away from the boost pump or tank outlet. This can happen when the aircraft is experiencing high gravity force/pressure.

Ancient Greeks is a civilization in the northeastern Mediterranean that dates back to the Greek Middle Ages from the 12th century BC to the 9th century BC. By the end of classical antiquity (about 600 AD), it consisted of a loose collection of culturally and linguistically related city-states and other territories. Under the empire of Alexander the Great (336–323 BC), was united only once, for thirteen years. In Western history, the period of Classical Antiquity was immediately followed by the Early Medieval and Byzantine periods.

A Descriptive norm describes what is commonly done in a situation, whereas an injunctive norm describes what is commonly approved or disapproved in a situation.
Descriptive norms are what most people in a group think, feel, or do. A normative or tentative norm is one that is approved by most people in the group. Here we make a distinction between what applies to group members and what applies to group members. Often, these two types of norms overlap.
Descriptive norms are perceptions of how people actually behave. For example, when asking a teenager how his parents behave with respect to alcohol, the descriptive norm may be "my parents don't drink much." In this case, the teenager explains how they think their parents actually behave.
