HG401 Advanced Techniques & Concepts Transition by T he word “transition” can be used in talking about many things, but when we hear it in hang gliding it has almost an iconic meaning. We fly our gliders in the prone position, with our hands on the basetube. We land our gliders with our bodies upright, and our hands on the downtubes. To get from A to B we “transition.” As simple as that may sound, it ain’t! To better understand a topic, it’s useful to ask the W (and one H) question words: What, When, Which, Where, Why, and How. Who is a W word as well, but in this case that is obvious—you, me, whoever the pilot may be. Starting with WHAT—the transition is working from prone to upright. Does that mean body position, hand position, or both? If I keep my hands on the basetube but rock my body upright, have I transitioned? I would say no, because I can’t really flare with my hands on the basetube, so I can’t be done yet. How about if I move my hands to the downtubes but don’t rock my body upright? Again, I probably don’t want to land like that, so I can’t be done yet. So what I’ve come to realize is that “the transition” actually consists of two elements, sometimes done simultaneously, but often done at different times. Either way can be effective with practice; I use both, depending on the situation. WHEN to transition is an easy answer: The transition needs to be completed—both parts as described above— before it’s time to flare. Unfortunately that is not very specific… because that could be the moment before you flare, or 10 seconds after launching. To narrow it down let’s first think r ya n voig ht about when NOT to transition. There is a specific time in every landing where it is near impossible to maintain control of the glider and transition, and that is on final carrying additional airspeed. With airspeed comes bar pressure, and letting go with one hand while there is bar pressure results in at least a pitch “bobble” where the nose pops up, or worse still an accidental heading change—the one hand you’re still holding on and pulling in with is on one side of the control frame, pulling your weight toward that side and turning the glider. Knowing when not to transition, we can clarify that we want to transition either before we turn on final and then pull in for extra speed, OR near the end of the ground-skim phase of the landing when we’ve bled off the extra airspeed and are nearing trim speed and there is little or no bar pressure. WHICH is the next question we face, because we must choose—transition before final or after ground skim. Both have their pro’s and con’s and neither is a simple choice. Transitioning before pulling in for speed gets the transition done early, leaving you less to have to do while performing your landing. It does, however, come with a catch: Pulling in for speed can be more difficult when flying from the uprights. Notice I said more difficult and not impossible; it CAN be done. In terms of physics, the glider feels your weight hanging from your harness mains and hooked in at the hang loop. When flying prone, pulling in to full arm extension puts the basetube about at your belt buckle, which is just a little farther forward than your harness mains. When upright, we can pull in until the basetube contacts our body—and when it does, our harness mains will be just barely behind the base- OPPOSITE Flying near the ground while prone means we still need to work a transition in before it’s time to flare—and if something goes wrong our injuries will likely be much worse.
