How fast does an airplane have to go to get off the ground?

Contents

Typical takeoff air speeds for jetliners are in the range of 240–285 km/h (130–154 kn; 149–177 mph). Light aircraft, such as a Cessna 150, take off at around 100 km/h (54 kn; 62 mph). Ultralights have even lower takeoff speeds.

How fast does a 747 have to go to get off the ground?

A fully loaded Boeing 747 ‘Jumbo Jet’ on a normal long haul flight would take off at a speed of around 160 knots which is 184 mph.

What speed does a 777 take off at?

The Boeing 777-200ER take off or rotate speed (VR) typically occurs between 130 – 160 knots (roughly 120-180 mph) depending on the weight of the aircraft. At a typical take-off weight of around 230,000 kgs, the take off speed would be approximately 145 kts which is approximately 165 mph.

How fast does a helicopter go?

An average helicopter can reach a top speed of somewhere between 130 and 140 knots, which comes out to about 160 mph. The Eurocopter X3 can reach a top speed somewhere in the neighborhood of 267 mph (430 km/hr or 232 kts) in stable and level flight.

How fast does a 747 cruise?

Answer: The Boeing 747 can cruise at 92% of the speed of sound, Mach . 92. It is very rarely flown at this speed due to the increased fuel burn required. Most modern jets fly around 80% of the speed of sound, Mach .

What’s the slowest speed a plane can fly?

Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph).

What is the fastest Boeing airplane?

Boeing 747-8

The 747 is one of the largest commercial aircraft ever built, and the 747-8 Intercontinental (747-8i) variant wins the race as the fastest commercial plane in service today. This plane is as tall as a six-story building with a top speed of Mach 0.86. That’s equivalent to 659.85 mph.
