What are the potential consequences of using the wrong fuel type?

Using the wrong fuel type can lead to significant problems for an aircraft, primarily manifested as engine damage or failure and reduced performance. Each aircraft is designed to operate with a specific type of fuel that meets particular chemical and performance standards. Using a different type of fuel can disrupt the proper combustion process, potentially causing a range of issues.

For example, jet fuels have specific properties such as flash point and viscosity, and using a fuel that does not meet these specifications can lead to insufficient lubrication, overheating, or even combustion failures. This can cause damage to critical engine components, leading to costly repairs or, in severe cases, complete engine failure during flight.

Additionally, the aircraft's performance could be adversely affected, as the engine may not produce the required thrust or may run inefficiently, leading to issues like decreased climb rate or increased fuel consumption. Therefore, choosing the correct fuel type is crucial for safe and efficient aircraft operation.
