On 24 October 2014, at the age of 57, Google’s Senior Vice President Alan Eustace set a new exit altitude record of 135,898ft (41,422 m) above Roswell, New Mexico, USA. However, skydivers really need to increase their height by huge distances in order to recognize an effect. As a result, they will accelerate faster and to a higher terminal velocity. (I will explain this relationship in more detail later in this post.)īecause air density decreases with increasing altitude skydivers will face less air resistance when jumping from 30,000 ft than from 10,000 ft.
it limits the terminal velocity skydivers can reach. Air resistance is the force that works contrary to the gravitational pull of the earth i.e.

Skydivers reach a higher terminal velocity during a HALO jump not only because of a longer free fall but also because of less air resistance. This is so high that the skydiver will require special equipment for breathing and navigating. If skydivers want to reach higher speeds, they can either change their body position or they can increase their jump height tremendously by performing a so-called HALO jump.Ī HALO jump classifies a jump with an altitude above 30,000 feet. Despite the higher jumping altitude, they would only reach a terminal velocity of 127.894 mp/h which will not feel any different to 127.893 mp/h. In comparison, experienced divers can go as high as 16,000 feet without oxygen support and would be able to enjoy at least 70 seconds of freefall. The skydiver is expected to reach a terminal velocity of 127.893 mp/h (206 km/h) after 12 seconds and a fallen distance of 1,500ft (450 m). In practice, however, normal skydives are not likely to recognize this effect.įor example, the normal skydiving altitude for beginners is between 10,000-15,000 feet which will allow the jumper between 30-60 seconds of free fall. In theory, it should hold true that the higher the jumping altitude is, the longer the freefall and the higher the terminal velocity will be.
The first important factor is jumping altitude.

The Four Factors That Determine The Terminal Velocity (And How To Manipulate Them) How The Jump Height Defines Terminal Velocity For Skydivers Skydivers can also attain higher speed and distance depending on the following four factors. As people often lose perspective for distances and time when skydiving, the question arises what distance and time are needed to reach terminal velocity.Ī typical skydiver on a belly-to-earth position will reach terminal velocity at a speed of approximately 120 mph (193 km/h) after 12 seconds of freefall and a fallen distance of 1,500 feet (450m). Skydiving is an adrenaline pumping and fun activity specifically due to the awesome feeling of falling at terminal velocity through the air.
