In the MTOW calculation, what is subtracted from ramp weight to obtain MTOW?

Explanation:
MTOW is the weight of the aircraft at the moment of takeoff. Ramp weight includes everything on board for the flight (payload, passengers, crew, and fuel) while the airplane sits on the ground. As the aircraft taxis to the runway, it burns taxi fuel, which reduces its weight. Subtracting that taxi fuel from ramp weight gives the weight at lift-off, i.e., MTOW. Passengers and crew are part of the ramp weight and remain onboard until takeoff, so they aren’t subtracted separately.
