  • The 747 parasitic drag, CDP, is 0.022, and the wing area is 5,500 square feet (511 m2), so that f equals about 121 sq ft (11.2 m2). The parasitic drag is given by ½ f ρair v² in which f is the product of drag coefficient CDp and the wing area.
  • Cruising speed shown at altitude. See NASA Mach number calculator page for Mach number explanation and example calculations.
  • "Required runway" length allows for emergency factors. Actual takeoff distances will normally be considerably shorter than those listed here. See Balanced field takeoff.
