Which is greater: Max Ramp Weight or Max Takeoff Weight?

• A. Max Ramp Weight 85,870 lb
• B. Max Takeoff Weight 85,517 lb
• C. Max Landing Weight 74,957 lb
• D. Max Zero Fuel Weight 69,886 lb

Answer: (A)

Understanding weight limits on the ERJ 175 involves comparing different weight states of the airplane. Ramp weight is the maximum weight allowed while the aircraft is on the ground (with payload and fuel loaded). Takeoff weight is the maximum weight allowed at liftoff, after the airplane has taxied and any fuel burn that occurs before takeoff has reduced the weight. In practice, you can load up closer to the ramp weight on the ground, but by the time you reach the runway and are ready to depart, some fuel will have been burned and the weight must not exceed the takeoff limit. That’s why ramp weight is often higher than takeoff weight. Here, the max ramp weight is 85,870 lb and the max takeoff weight is 85,517 lb, so the ramp weight is greater by 353 lb. The key takeaway is that you can be loaded heavier on the ground than you are allowed to be at the moment you lift off, thanks to fuel burn and other pre-takeoff weight changes.
