The aerial phase of ski jumping was investigated from a physical point mass, rather than an athleteβaction-centered perspective. A total of 93 jumps performed by 19 athletes of performance level, ranging from junior to World Cup, were measured.
Based on our analysis, we propose a generic algorithm that identifies the stable flight based on steady glide aerodynamic conditions, independent of hill size and the performance level of the athletes. Ski jumping is a popular winter sport, with an Olympic history dating back to [ 1 ]. In previous research, the consensus has been to divide a ski jump into four main phases: inrun, take-off, flight, and landing, where the flight phase is subdivided into three phases: early flight, stable flight, and landing preparation [ 2 ], as shown in Figure 1.
A ski jumper aims to gain the highest speed possible through the inrun [ 3 ], while establishing the best possible conditions for the phase considered to be most influential on performance, the take-off, where the initial conditions for the flight are created [ 2 , 4 , 5 ].
The early flight phase spans from where the ski jumper is airborne until a steady flight posture is reached. The aim of the early flight phase is to reach stable flight as quickly as possible, with minimal speed loss [ 6 , 7 , 8 , 9 ]. Graphical overview of a ski jump with the separate phases a ski jump is divided into. The stable flight phase is the part where the ski jumper maintains a fairly constant flight posture, i.

In this phase, the aerodynamic forces are highly influential and the ski jumper intends to achieve as high of a lift-to-drag-ratio L D -ratio as possible [ 2 ].
