| NOTES: | (1) ALL PERFORMANCE FIGURES ARE ESTIMATES and can vary by atmospheric conditions or other factors. | ||||
| (2) All tests performed starting at max takeoff weight (656,000 lbs) and climbing at autopilot-managed climb rate; maintaining 250 KIAS until 10,000, then at 300 KIAS until speed decay. | |||||
| (3) Autopilot-managed climb started to produce airspeed decay around 25,000; stall conditions started above 32,000. Autopilot-managed climb to high altitude at max takeoff weight not recommended. (Autopilot performance is much better at lower weights.) | |||||
| (4) Estimated using weight differential over a one-minute cruise. | |||||
