Guidance for the Aviation Medical Certification of HIV Seropositive Persons

The medical certification of persons with HIV seropositivity will be considered as is the case for any other acute or chronic disease process: using medical information, clinical presentation and aeromedical concerns to determine the risk of subtle or sudden incapacitation during the validity period of the aviation license or permit held by the document holder or applicant.

In the case of HIV/AIDS, much is known about the natural course of the disease, the influence of treatment protocols, the side effect profiles of medications used, the potential for significant physical and psychological dysfunction arising from the disease and treatment, and the potential for periods of medical stability.

Transport Canada Civil Aviation Medicine will consider applicants with HIV seropositivity for all classes of aviation medicine certificates. Such issues as severity of disease, treatment protocols, side effects of treatment, potential for cognitive impairment and general prognosis will influence the aeromedical decision making with respect to licensing fitness and/or limitations and follow-up requirements.

Considerations

As a general principle, an applicant will be considered UNFIT for medical certification if there is evidence of:

  • AIDS defining illnesses (Appendix A),
  • unstable course of disease, or
  • progression to CDC Stage 3 ,

Persons experiencing remission, resolution and/or stability of AIDS defining conditions may apply for consideration

All HIV seropositive applicants will need to provide the following supporting medical documentation for consideration;

  • detailed medical report from attending infectious disease specialist
  • CD4+- count
  • Viral load
  • Neuropsychological testing
  • Serology for other infectious diseases

An applicant not on anti-retroviral therapy (ART) may be considered for medical certification if the CDC stage 1 or 2conditions are met:

  • HIV infection Stage 1
  • No AIDS defining condition
  • CD4-+ T-Lymphocyte count > 350 cells/mL

Note: Current Canadian clinical guidelines suggest that CD4+ count of less than 350 cells/µL is an indication for initiation of anti-retroviral therapy.

An Applicant on ART may be considered for medical certification if:

  • HIV viral load below level of detection,
  • Any CD4+- count
  • No aeromedically significant side effects from the medication.

If on anti-viral treatment (ART) applicants will need to submit additional medical reports documenting :

  • dosage and type of medication.
  • Medication side effect profile
  • CBC, liver function tests, lipids
  • Cardiac assessment (depending on cardiac risk profile)

Medical Certification

Medical Certification may be granted as FIT or FIT with Limitations, and may have specific validity period limitations, and will require specific and regular follow-up medical reports to maintain certification.

Follow-up

Follow-up reports requirements will be individualized but, as a minimum should include:

  • Detailed report from attending physician/infectious disease specialist every six (6) months or sooner if condition changes radically
  • Neuropsychological report or equivalent annually,
  • Cardiovascular risk assessment (individualized schedule) if on ART

Note:

The Aviation Medical Review Board (AMRB) may provide recommendations on the risk assessment of individual applicants who present with more complex issues.
