Mission Performance Clause Samples

Mission Performance. For a mission with an equivalent still air range (stage length) of 1,600 nautical miles, when operated under the conditions specified below,. the block fuel burnt shall be not more than 10,217 lb (4,634 kg) when carrying a fixed payload of 10,250 lb (4,649 kg) representative of 50 passengers at 205 lb (90.3 kg) per passenger. The mission is flown at ISA conditions throughout. Climb is made starting at sea level to 35-000 ft pressure altitude using a climb speed schedule of 250 KCAS / 0.70 M. Initial cruise is at 35,000 feet pressure altitude at a cruise Mach number of 0.74 M. Step climb is made starting at 35,000 feet to 37,000 feet pressure altitudes using a climb speed schedule of 250 KCAS/0.70m. Final cruise is at 37,000 feet pressure altitude at a cruise Mock of 0.74m. Thrust during both cruise is not to exceed maximum cruise thrust. Descent is made from 37,000 feet pressure altitude to sea level using a descent speed schedule of 0.70 M / 250 KCAS. For the purpose of this guarantee the following are fixed quantities and allowances: - 1 minute take-off fuel including acceleration to initial climb speed is 107 lb (49 kg). - Usable reserve fuel remaining upon completion of descent phase, based on the reserve profile specified below is 1,866 lb (846 kg). 1) 100 nm (185 km) diversion including: i) climb from sea level to 22,000 ft at a speed of 250 KCAS ii) cruise at 22,000 ft at long range cruise speed iii) descent to sea level at a speed of 250 KCAS 2) plus fuel equivalent to 45 minute hold at 22,000 feet at minimum drag speed (Vmo). The stage length is defined as the sum of the climb, cruise and descent distances. M denotes true Mach number. Block fuel includes engine start, taxi, take-off, climb, cruise and descent. The fuel burn guarantee is based on the fixed estimated OWE of 30,800 lb (13,971 kg).
