CONCLUSION It is possible to use the Cosmed K 4 B 2 in “high level” glider aerobatic
We got interesting information about every phase of the flight and especially about the aerobatic flight
It is very important to use together “K 4 B 2” and video recording because of the unreliability of GPS due to “g”
The research may be extended to different: • pilots • aerobatic programmes • phases of training
