Its better to practice in good conditions so that you are prepared for the worst. Most new canopies can be flown straight in, even at very high wing-loadings, with proper technique. If you can't do it, you probably need to work on technique. There are times when high-speed approaches are unsafe, due to heavy traffic in the air or on the ground, when you are angry or tired, when you are disappointed with your performance, or when the weather conditions are marginal. B. Verify that the technique you wish to use works well with the canopy you are using.
Some canopies have unusual flight characteristics that can take hundreds of jumps to fully explore.
Do this exploration up high away from other traffic. Some canopies can become unstable using certain techniques. C. Stay with straight-in approaches, working on flaring technique for many jumps to obtain the longest swoop possible before attempting any turning approaches. Many people do not work on improving their technique long enough before trying aggressive turning approaches. Many tend to react too late to changing circumstances, and then over control afterwards.
