The Drop

News and Resources from AXIS Flight School


On January 4th, 2015 AXIS Flight School created an experimental dive pool for what was then referred to as XRW (Extreme Relative Work). This is a still developing discipline where canopy and wing-suit pilots build formations. In essence, an XRW skydive is a dissimilar formation flight.

The first dive pool developed by AXIS was called XF. The name change from XRW was proposed similar to how RW (Relative Work) was changed to FS (Formation Skydiving); and since CF (Canopy Formation) is already taken, the XF abbreviation was introduced for “Cross” Formation. The first draft only had 3 Randoms and 6 blocks.

Since wing-suit technology has dramatically increased flight performance over the past few years, new formations have become possible. The updated 2020 version now features 8 randoms and 10 blocks dispersed over three classes: intermediate, advanced, and open. In addition, the XF rules have been updated to evolve with the times and practitioners can even make use of the AXIS DrawGenerator. There are now two orientations for the wing suit pilot to fly in:

  • Normal (belly to earth) – indicated in gray, and
  • Inverted (back to earth) – indicated in red.

AXIS coach Niklas Daniel started experimenting with XF back in April 2010, and has posted videos and written articles about the subject.

2015 – XF gets some exposure on Discovery Canada with first 3-way Night Formation.

Continued fun, experimentation, and introducing the discipline to others.

    Nik, it was nice seeing you the other day. I am gonna try to get up there and jump soon. I know currency and practice are really the keys. The main take away for me from your class is break off higher if doing group stuff and/or pull higher. For me, the decision altitude is 2500 feet. The window ends there, it does not begin there. I also went to Erin’s emergency class and John L ‘s Anatomy of a reserve class. I am a little fuzzy on some aspects of the MARD. At some point, I will probably ask you a couple of question about that subject. For me , the realities of my life and my philosophical approach to skydiving don’t Incline me to do 100 jumps per year. However, I think, but do not guarantee, that the stuff you helped me pound into my head allow me to have a safe small niche to do a few safe jumps occasionally. When I drive into that very serious DZ now, I do feel more confident getting on a load. I feel that I can safely, but not impressively, do it. From there just being in freefall solo is a gas to me. At that point, it can be akin to a spiritual feeling for me. Different strokes for different folks. If everybody is thinking alike, somebody is not thinking. Well, that is it. I hope that I didn’t ramble too much.
