On Wednesday, November 12, 1975, Boeing’s 747 SP left JFK on a nonstop flight to Tokyo. This was the first of several long flights scheduled for the SP’s world-wide demonstration tour. The flightplanned time was 13 hours and 28 minutes. The actual flight time was 13 hours and 35 minutes.
The takeoff gross weight of the airplane was 675,000 pounds with a takeoff fuel load of 319,000 pounds. Cruise altitude was initially established at 35,000 feet at .84 Mach, from which a step-climb regime was instituted. This carried the airplane through 37, 39, 41 and 43, to 45,000 feet where it cruised for about 2 hours. The average wind component for the flight was minus 32. The flight was never more than five minutes off the flight plan at any time.
At top of descent to Tokyo, fuel aboard was sufficient for diversion to Osaka, the most distant alternate, if it had been necessary. After landing at Tokyo, the fuel remaining was 30,400 pounds, indicating fuel consumed was about 289,000 pounds. While this shows favorable fuel economy on a long nonstop flight, Boeing feels there is room for some improvement in this area and is currently engaged in a drag reduction program.
Captain Will Brown and Flight Engineer Stan Sabalis, who made up the Pan Am operating flightcrew said the airplane met every expectation.
After visits to Taipei, Singapore, Kabul and Bombay, the SP flew to Sydney, then to Santiago, a distance of 7,143 miles in 12 hours and 14 minutes. After Santiago, the SP went on to La Paz, the world’s highest commercial airport, where it landed with less than 4,000 feet of runway. At takeoff, with 156 government and airline guests aboard, the airplane used less than 7,000 feet of
runway.
The itinerary calls for stops at Quito, Caracas and Mexico City, then nonstop to Belgrade, a distance of more than 7,000 miles. Other destinations include Athens, selected cities in Africa, then on to Kingston. The SP returns to Seattle on Wednesday, December 10.
It is noteworthy that since leaving Seattle on November 11 the airplane has not experienced any mechanical delays. It had flown less than eleven hours prior to starting the tour.
At this time, certification of the SP is about 95% complete. While not actually part of the certification program, it is hoped that a percentage of the 135 flying hours accrued on this world-wide flight may be applied to the final certification. □
