Does anyone know what the thrust-to-weight ratio is for the Airbus A330-900neo?
I'm getting different numbers when I try to calculate this for myself.

The thrust-to-weight ratio is not a single number because both thrust and weight vary throughout a flight:
The thrust-to-weight ratio varies continually during a flight. Thrust varies with throttle setting, airspeed, altitude and air temperature. Weight varies with fuel burn and payload changes. For aircraft, the quoted thrust-to-weight ratio is often the maximum static thrust at sea level divided by the maximum takeoff weight.
For standard sea level conditions with maximum takeoff thrust and at maximum takeoff weight, we would get the following numbers (source) for the A330-900:
|Thrust / Engine||Total Thrust||Mass||Weight||Thrust-to-weight ratio|
|324 kN||648 kN||251 t||2462 kN||0.263|
