Fuel burn is the amount of fuel an aircraft consumes during a flight. It depends primarily on the engine’s specific fuel consumption and the duration of the flight, which in turn is set by the distance to be covered and the aircraft’s ground speed.
Ground speed is the sum of the aircraft’s true airspeed and any wind component along the flight path. A tail‑wind (positive value) shortens the flight time, while a head‑wind (negative value) lengthens it. The relationship can be expressed mathematically.
Once the flight time (t) is known, the total fuel burn (F) is simply the product of the aircraft’s fuel‑burn rate (R, in kg/h) and the time: F = R × t. This linear model provides a quick estimate useful for planning and budgeting.
