A jumbo jet, also referred to as the Boeing 747, normally flies at Mach 0.92. However, these aircraft usually cruise at Mach 0.88. The speed of the plane varies with the altitude, since it influences the density of the atmosphere.
Pilots normally fly jumbo jets at speeds much lower than their maximum because of various economical reasons. Lower speeds are considered more efficient in terms of costs and safety. Flying a Boeing 747 at maximum speed will increase the chances of damage and failure of control surfaces. Pilots have more control over the aircraft when flying at lower speeds, and they find it easier to maintain control especially when entering a dive.Learn More
