Explanation of Payload-Range DiagramBoundariesFrom this diagram three corner points representing combinations ofrange and payload are labeled with roman numerals (I-III). Anexplanation of these points follows.Operating point (I) represents an operational point where theaircraft carries its maximum payload at departs the origin airport atmaximum takeoff gross weight (note the brake release gross weightboundary) of 297.6 metric tons.The corresponding range for condition (I) is a little less than 5,900nautical miles. Note that under this conditions the aircraft can carryits maximum useful payload limit of 56,900 kg (subtract 195,000 kg.from 138,100 kg. which is the OEW for this aircraft).Virginia Tech - Air Transportation Systems Laboratory 84
Payload-Range Diagrams ExplanationsOperating Point (II) illustrates a range-payload compromise whenthe fuel tanks of the aircraft are full (note the fuel capacity limitboundary).Under this condition the aircraft travels 8,600 nm but can only carry20,900 kg of payload (includes cargo and passengers), and a fuelcomplement of fuel (171,100 liters or 137,460 kg.).The total brake release gross weight is still 297.6 metric tons forcondition (II).Virginia Tech - Air Transportation Systems Laboratory 85
