**What is the average speed of a plane?**

Planes come in all different shapes and sizes, e.g. passenger planes, small propeller planes and jet-fighters.

The following overview shows the average speed of various planes:

Type of plane |
Average speed |

Small plane | 124 mph (200 km/h) |

Airliner | 621 mph (1.000 km/h) |

Jet | 1243 mph (2.000 km/h) |

**What influences the average speed of a plane? **

The weather has a large influence on the average speed of a plane. For instance, a plane flying with tailwind can reach far over 621 mph (1,000 km/h), whereas flying against strong winds decreases the speed to an average of only 373 mph (600km/h).

**Has the average speed of planes increased over the years?**

Yes, the average speed of planes is still increasing. Advances in technology, in particular, have ensured that airlines can continue to increase the average speed of their planes. To compare: a current passenger plane flies an average 621 mph (1.000 km/h), in the 70’s the average speed was 497 mph (800 km/h).

**What is the fastest plane in the world?**

The X-15 rocket plane is the fastest manned plane ever built. This plane has a top speed of 4000 mph (6.437 km/h). The fastest unmanned plane is the Falcon-HTV-2. This plane is developed to react fast to terrorist attacks and can reach a speed of over 12427 mph (20.000 km/h), meaning it can fly from Sydney to London within an hour!
