Ramp weight vs takeoff weight definitions.

• A. Ramp weight is the aircraft weight with all fuel and cargo loaded at the ramp just before engine start; takeoff weight is the weight after engine start and taxi, before liftoff (fuel burn during taxi is typically not counted in ramp weight).
• B. Ramp weight and takeoff weight are the same.
• C. Ramp weight is weight after liftoff.
• D. Ramp weight excludes fuel.

Answer: (A)

Weight is defined by the moment you measure it. Ramp weight is the aircraft’s weight on the ramp with all fuel and cargo loaded, and that measurement is taken before engine start. Takeoff weight is the weight during the actual takeoff phase—after engine start and taxiing—just before liftoff, so it has already accounted for any fuel burned while taxying. The difference between the two is the fuel burned during taxi.

That makes the described option the best fit: ramp weight includes full fuel on board loaded at the ramp before start; takeoff weight is after taxi, with the reduced weight from that on-ground fuel burn. It’s not the same as liftoff weight, it doesn’t exclude fuel, and it isn’t weight measured after liftoff.
