Airsickness is a significant obstacle in the training of some student pilots. When conventional therapy fails, desensitization therapy may be indicated. Using experience gained by the RAF and USAF, the Canadian Forces (CF) began such a program in 1981. This paper reports program results from 1981-1991. Following subject identification, treatment consists of three phases: biofeedback relaxation therapy, ground-based desensitization training and in-flight desensitization therapy with a pilot-flight surgeon. Employing a definition of cure used by the RAF, success was compared with that of the RAF and USAF programs. A total of 22 student pilots have undergone rehabilitation, 17 of whom have been successfully treated for a success rate of 77%. This is comparable to success rates of other programs. It is reaffirmed that desensitization is a valid clinical tool in treatment of airsickness.
