What is one aspect that does not influence a 'go/no-go' decision?

The availability of flight attendants is generally not a primary factor influencing a 'go/no-go' decision for a flight. This decision is primarily centered around critical operational factors that directly affect safety and compliance with regulations.

In contrast, aspects such as the condition of the aircraft are vital to ensure that it is airworthy and can operate safely. This includes checking for any mechanical issues, ensuring that all required maintenance is up to date, and verifying that safety equipment is present and functioning properly.

Weather conditions play a significant role as well; adverse weather can affect visibility, turbulence, and other flight dynamics, all of which are crucial for safe flying. Pilots must evaluate these conditions and decide if the flight can operate safely or if it needs to be postponed or canceled due to safety risks.

Local aviation policies also weigh heavily in the decision-making process. These policies can dictate operational procedures, such as minimum equipment lists, safety protocols, and airspace utilization rules, which can all determine whether it's safe or compliant to proceed with a flight.

Thus, while flight attendants contribute to the overall operation of a flight, their availability does not directly impact the fundamental safety decisions critical to launching an aircraft.
