The total mass limit of a light twin is equal to 3200 lb. The pilot weighs 200 lb and the combined mass of the passengers and their baggages is 850 lb. Assuming a Dry Operating Mass of 1742 lb, how much fuel can be loaded?

  • A

    367 kg

  • B

    608 kg

  • C

    276 kg

  • D

    311 kg

Dry Operating Mass (DOM) is the sum of the Basic Empty Mass (BEM) and the Variable Load (crew, crew baggage, food, beverages, water etc.), excluding both usable fuel and payload. So, the pilot's mass is included in the DOM.

Thus, the fuel that can be loaded is: Total mass limit - DOM - Passengers & Baggage = 3200 lb - 1742 lb - 850 lb = 608 lb.

Convert lb into kg: 608 lb / 2.2 lb per kg = 276 kg.

NOTE:

Be careful with the units of measurement. Apply the unit conversions where necessary.
