What is the difference in pounds between Max Ramp Weight and Max Takeoff Weight?

• A. 353 lb
• B. 1,000 lb
• C. 0 lb
• D. 2,000 lb

Answer: (A)

The difference between Max Ramp Weight and Max Takeoff Weight is the fuel you expect to burn between loading the aircraft on the ramp and reaching takeoff weight. In practice, you can carry more fuel on the ramp than you’re permitted to lift off with, because some of it will be burned before liftoff to meet MTOW. For this aircraft, that margin is 353 pounds, which is about 50 gallons of Jet-A fuel (roughly 6.8 lb per gallon). This reflects taxi and engine start burn needed to reduce weight from MRW to MTOW. The other numbers don’t fit because they’d imply either no burn (0) or an unrealistically large taxi fuel burn (1,000 or 2,000).
