Guidance Material

Polycystic Ovary Syndrome (PCOS)

Applicants with a diagnosis of polycystic ovary syndrome (PCOS) should inform the Authority (Class 1) or Aeromedical Examiner (AME) (Class 2). Ongoing medical certification is subject to a specialist gynaecologist report. This should include a cardiovascular and metabolic risk assessment and review of any symptoms of obstructive sleep apnoea (OSA). A diagnosis of cardiovascular, metabolic disease or OSA entails unfitness and risk factors should be addressed.

Hormone manipulation therapy is acceptable subject to confirmation of no side effects and adequate symptom control. Note: Metformin & thiazolidinediones are unlicensed for use in PCOS and may only be used in consultation with the Authority's Medical Department on a case-by-case basis.

Endometriosis

Applicants with a first diagnosis of endometriosis should be assessed as unfit. Recertification is considered subject to a specialist gynaecologist report. Recertification is considered if the applicant is symptom free, on minimal analgesics and/or has minimal side effects from hormone manipulation therapy. Surgery entails unfitness. (See below)

Menopause and Hormone Replacement Therapy (Appropriate to all certificate classes)

Applicants suffering symptoms of the menopause should consult their own GP or gynaecological specialist in the first instance, who should give consideration to whether treatment is appropriate or not. A potential side effect and cardiovascular risk review should be addressed as part of treatment option considerations.

Once a treatment and/or follow-up plan is instigated, the applicant should consult with their AME as to whether there are any current or predictable symptoms, particularly mental health and well-being, together with any common side effects of treatment experienced, that might affect the safe exercise of licence privileges. If such symptoms are experienced, and/or while treatment is commenced, a temporary period of grounding may be considered if necessary.

Gynaecological Surgery

The period of unfitness will vary according to the type of surgery and any post-operative complications. A minimum period of 1 week should elapse after a Dilatation and Curettage (D&C), 6 weeks after laparoscopic hysterectomy, 8 weeks after vaginal hysterectomy and 12 weeks after an abdominal hysterectomy. Laparoscopy involving insertion of gas in to the abdominal cavity may require 2 weeks prior to returning to flying. A gynaecological report should be obtained.

Menorrhagia

Applicants requiring specialist investigation for menorrhagia should be assessed as unfit. Recertification is considered subject to a satisfactory specialist gynaecologist report. The applicant should be symptom free and/or have minimal side effects from hormone manipulation therapy. Haemoglobin should be within normal limits. Surgery entails unfitness until symptom-free following recovery.

In Vitro Fertilisation

Applicants undergoing a first cycle of In Vitro Fertilisation (IVF) should be made unfit. Subsequent recertification may be considered subject to an acceptable specialist gynaecology / obstetric report. The report should confirm no evidence of continuing ovarian hyperstimulation or other associated side effects and intended future management plans including medication. If the cycle is successful, the Civil Aviation Authority (CAA) pregnancy guidance material should be followed, i.e., the applicant can be assessed as fit subject to confirmation of a healthy pregnancy supported by an acceptable medical report and continuing clinical follow-up plan.

Periods of unfitness for subsequent cycles should be determined according to the issues experienced during previous cycles. Applicants are advised to seek the advice of their specialist relating to the interaction of work activities on the likely outcomes. If previous cycles were uncomplicated and the treatment plan unchanged, then a period of unfitness from a flight safety perspective may not be necessary. Complex Class 1 and 3 applicant cases should be referred to the CAA.

Pregnancy 

Applicants should be advised to give a copy of the pregnancy information sheet for pilots and air traffic controllers to their midwife or doctor, for inclusion in their medical notes.

Miscarriage or Termination of Pregnancy

Applicants who suffer a miscarriage or have a termination of pregnancy should be assessed as unfit.

Recertification is considered subject to a GP or gynaecologist report. The report should confirm they have fully recovered, with no residual symptoms, a normal haemoglobin and comment on psychological status. Before returning to flying Class 1 applicants should undergo an assessment by their AME of their psychological state.
