What is fuel policy and fuel monitoring?

In a little while, you will begin practicing practical planning with single-engine, multi-engine, and medium-range jet transport aircraft. As you will see, we input several tables and graphs for these aircraft kinds. By using them, we can determine how much fuel will be needed for a certain flight duration under various aircraft weight, air temperature, and wind component conditions. As long as the actual weather is similar to the predicted values used to create the plan, these forecasts are typically fairly accurate. This is known as the Trip Fuel.
That is insufficient on its own, though. The engine would go out due to gasoline starvation the instant we reached our destination if we had only the trip fuel on board when we took off, which is obviously not a safe operating procedure. It is obvious that we require more fuel than the bare minimum to complete the journey. We do, after all, begin utilizing fuel prior to takeoff. We need to think about cab and startup. Additionally, we require reserve fuel in order to taxi in and shut down as well as in case the trip does not proceed as expected.
The standards governing how much fuel should be carried on an air transport flight have been agreed upon worldwide and are outlined in CS-OPS 1. While the actual numbers vary by aircraft type since various aircraft consume varying amounts of gasoline, the regulations remain the same. The methods used to calculate the minima for each flight are universal.
This is referred to as the EASA Fuel Policy.
