The average cruising flight speed for commercial jets is around 540 mph. This is based on the most popular commercial jets in operation, the Boeing 747 family.Know More
Some models of jets have been designed to reach much higher speeds than the average of 550 mph. Typically, these planes are designed for a limited number of passengers. One example is the Gulfstream G650 from Gulfstream Aerospace, which reaches speeds of up to 904 mph.
Large passenger planes, such as the Boeing 747-8, can hold up to 700 passengers and reach cruising speeds of 649 miles per hour.
Although it is decommissioned, the Tupolev TU 144 ran 55 flights from the 1960s to the '90s. Each flight held as many as 140 passengers and traveled at more than 1,000 mph.Learn more about Airplanes & Helicopters
Airplanes fly because the design of the wings produces lift that counterbalances the weight of the aircraft. Air flows more rapidly over the top of the wing than underneath it, which reduces the air pressure above the surface. The higher pressure below, exerted over the surface of the wing, pushes the aircraft upwards. Achieving lift requires enough forward speed to keep the air moving fast enough to create this force.Full Answer >
The world record for the highest helicopter altitude is 40,820 feet. This record was set on June 21, 1972 by French pilot Jean Boulet, who flew an Aérospatiale SA 315 Lama without a payload. He achieved this feat while flying over the Aérodrome d'Istres in France.Full Answer >
The greatest certified height reached by a commercial airliner as of February 2014 is 60,000 feet. Although greater heights can be dangerous for equipment as well as passengers, there is little turbulence after an aircraft flies above 50,000 feet.Full Answer >
The most-advanced helicopters can fly up to 300 miles before having to refuel. How long any particular helicopter can fly without refueling depends on the size, weight and age of the helicopter.Full Answer >
