solving problems of this nature, peer and family support appears to be significant and the opportunity to
discuss such problems with sympathetic management or a designated colleague or personnel officer or,
more particularly, with an understanding DME, is important. Experience has shown, however, that some
controllers still report a build-up of stress because apparently none of these channels is available to them.
PREGNANCY
The relevant requirements in Chapter 6 of Annex 1 are as follows:
6.5.2.22 Applicants who are pregnant shall be assessed as unfit unless obstetrical
evaluation and continued medical supervision indicate a low-risk uncomplicated
pregnancy.
6.5.2.22.1 Recommendation.— During the gestational period, precautions should be

taken for the timely relief of an air traffic controller in the event of early onset of labour or
other complications.
6.5.2.22.2 Recommendation.— For applicants with a low-risk uncomplicated
pregnancy, evaluated and supervised in accordance with 6.5.2.22, the fit assessment should
be limited to the period until the end of the 34th week of gestation.
6.5.2.23 Following confinement or termination of pregnancy the applicant shall not be
permitted to exercise the privileges of her licence until she has undergone re-evaluation in
accordance with best medical practice and it has been determined that she is able to safely
exercise the privileges of her licence and ratings.
There is no published evidence to suggest that there is increased risk to mother or foetus as a result of
working with radar screens or VDUs.
VISUAL PROBLEMS
Refractive errors
Air Traffic Controllers should be able to read radar screens, visual displays and written or printed material
and also to make use of distant vision through control tower windows. If correction is needed to perform
one or more of these tasks, one pair of glasses should meet the requirements, so that it is unnecessary to
remove or change the glasses when operating. Contact lenses may be appropriate if tolerance has been
achieved.
It is an advantage if the optician who dispenses the glasses for the ATCO is familiar with the working
environment, particularly with regard to operating distances and ambient lighting.
Presbyopia
Controllers report a high incidence of problems with vision as they get older. Today’s sophisticated
equipment requires the ATCO to operate at near and intermediate distances and often change quickly
between these and long distance. Special correcting spectacles, suitable only for the work place, may be
necessary. “Look-over”, bifocals or multifocals may be the answer, and often these will correct for near and
intermediate distances while leaving long distance uncorrected. Varifocal lenses are a good solution for
many although they may cause some peripheral distortion and often require several days of familiarization
before they can be used on duty. Single-vision near correction (full lenses of one power only, appropriate
for reading) may be acceptable for certain air traffic control duties (whereas they are not for pilots).
However, it should be realized that single-vision near correction significantly reduces distant visual acuity.
FLEXIBILITY
In some specific cases of ATCOs not meeting the medical Standards in Chapter 6 of Annex 1, it may be
desirable to exercise flexibility in accordance with 1.2.4.8. In such cases, as mentioned under the section on
coronary heart disease, the licence may be endorsed as follows: “Subject to a similarly qualified controller
being in close proximity while the licence holder is exercising the privileges of the licence”.
