Abstract:

The purpose of this research was to compare complex monitoring performance and motion sickness symptomatology during hurricane penetration in three types of aircraft. Three different Navy aircraft made six flights, each flight penetrating hurricane Inga several times. The controlling aircraft a C- 121 is routinely employed by the Navy for hurricane penetrations. The other two aircraft C-130 and P-3 followed the C-121 into the storm at short intervals and penetrated the storm at the same altitude, heading, airspeed, etc. Most subjects experienced slight to moderate malaise during the flights with generally higher sickness rates occurring during the more turbulent flights. The subjects overall flying experience afforded some protection. Airsickness rates in the C-121 were greater than those in the C-130 and P-3. The results on a complex counting task showed that performance decreased as a function of increased turbulence. Author
