tilii:
If you want to spend your time arguing about the meanings of words, as in your definition of "medical condition", then knock yourself out.
Here's the facts:
JAR-FCL 3.040 Decrease In Medical Fitness
[(c) Holders of medical certificates shall, without undue delay, seek the advice of the AMS, an AMC or an AME when becoming aware of: ]
[(3)] being pregnant,
shall inform the Authority in writing of such injury or pregnancy, and as soon as the period of 21 days has elapsed in the case of illness. The medical certificate shall be deemed to be suspended upon the occurrence of such injury or the elapse of such period of illness or the confirmation of the pregnancy, and:
[(5)] in the case of pregnancy, the suspension may be lifted by the Authority for such period and subject to such conditions as it thinks fit (see JAR-FCL 3.195(c) and 3.315(c)) and shall cease upon the holder being medically examined under arrangements made by the Authority after the pregnancy has ended and being pronounced fit to resume her functions as a member of the flight crew.
So whatever you may think, the case is clear-cut. Complain to JAR if you want.
If the lady can get the suspension lifted under 3.195(c) and 3.315(c) then good luck to her.
Or are you arguing that it is OK to fly without a valid medical ??
