1. Physiological factors in glider aerobatics

2. FLIGHT, PILOT AND INSTRUMENTATION
FLIGHT Place = “Alfina” AIRFIELD (Orvieto – Italia) Date = 30 / 04 / 2010 Glider = MDM FOX D-7309 Programme = “Artistic Free Programme” as in World Air Games 2009 PILOT Name = Pietro Filippini Age = 61 years old Hours of flight = Italian and WAG Champion INSTRUMENTATION metabolimetro “Cosmed K4B2” Video camera “voice recorder”

3. Graphic representation of the “Artistic Free Programme”
of the WAG winner
Pietro Filippini

5. DATA CONCERNING THE COMPLET TEST (DURATION 24’ 38”)
TEST PHASES
1 BEFORE TAKE OFF AFTER ON BOARD ARRANGEMENT
2 TAKE OFF
3 TOW FLIGHT
4 AEROBATIC PROGRAMME
5 LANDING

7. THREE CHARACTERISTIC FIGURES OF THE PROGRAMME the “ITALIAN EIGHT” the “SUNFLOWER” the “RAINBOW”

8. The “ITALIAN EIGHT” Entry speed = km/h 220
Exit speed = km/h 90 (inverted flight)
DURATION = 26 sec.
“g” MAX = 5,0 POS/1,0 NEG
Exposure to over 3 pos. “g” = never more than 3 sec.

9. The “ITALIAN EIGHT”

10. The “ITALIAN EIGHT”

11. The “ITALIAN EIGHT”

12. The “SUNFLOWER” Entry speed = km/h 220 (vertical flight down)
Exit speed= km/h 270
DURATION = 21 sec.
“g” MAX = 5,0 POS/5,0 NEG
Exposure to over 3 pos. “g” = never more than 3 sec.
Exposure to over 3 neg. “g” = 4 sec.

13. The “SUNFLOWER”

14. The “SUNFLOWER”

15. The “SUNFLOWER”

16. The “RAINBOW” Entry speed = km/h 280 Exit speed = km/h 250
DURATION = 17 sec
“g” MAX = 7,0 POS/0,0 NEG
Exposure to over 5 pos. “g” = 4 second
Ballistic flight = 12 second

17. The “RAINBOW”

18. The “RAINBOW”

19. The “RAINBOW”

20. It is possible to use the Cosmed K4B2 in “high level” glider aerobatic
CONCLUSION
It is possible to use the Cosmed K4B2 in “high level” glider aerobatic

21. We got interesting information about every phase of the flight and especially about the aerobatic flight

22. It is very important to use together “K4B2” and video recording because of the unreliability of GPS due to “g” 

23. The research may be extended to different:
pilots
aerobatic programmes
phases of training
