Site Analysis

by BASEwiki

This section contains information you can use when analyzing a new jump site. This doesn’t necessarily have to be a site that has never been jumped. The fact that others have jumped an object before you, does not reduce the need for site analysis. The object and context may have changed. More importantly, you need to decide if the site fits your current jumping skills.

In general, site analysis can be split into three distinct considerations.

  1. The Approach
  2. The Jump
  3. The Getaway
  4. Approaching

The approach of an object considers what it takes to reach the exit point and being able to jump. On most legal objects like the Potato Bridge the approach considerations are dead simple; you walk out to the object with respect for general BASE ethics and site considerations.

For other objects, the approach can be a lot more involved. There are objects that have downright bizarre approach considerations like: drive up the left side of the dirt road, keep your lights on until you reach the third door, park behind the loading dock and leave a sixpack near the car.

Most often, approach complications fall in one of two categories; you are trespassing and need to avoid being seenor the exit point is remote and requires climbing and mountaineering skills.

Jumping

Obviously the jump part is a crucial part, since if the object wasn’t jumpable you wouldn’t be looking at it. This part of site analysis considers just the object, the winds and the landing area.

It removes all considerations that are invariant to the context the object resides in. Imagine being able to lift up the object and landings areas and putting it in another context. The technicalities of the jump don’t change, and this is what the jump aspect of site analysis considers.

Getting Away

Your getaway plan is the most important part of the entire jump analysis. Whenever you attempt to make a jump, your success is not determined by the jump itself. It is measured by how many of your crew came home without injury and without arrest. Your getaway plan will allow you to maximize this number. Whether or not you actually made a jump is of much lesser importance.

As with approach considerations, getting away becomes complicated because you might be trespassing or because you find yourself in a remote part of the planet. Your getaway plan is usually more extensive than your approach plan. This is because your approach plan considers the ideal situation and only minor deviations. Your getaway plan is what allows you to handle sudden changes to the ideal situation. What if

  • The weather or site conditions change during the approach
  • Somebody on the load decides not to jump
  • Somebody on the load is seen
  • Somebody on the load is caught
  • Somebody on the load is injured or worse
