Aviation authority restricting licences by airline
Hello all!
Not sure if this the correct forum for this but I'll go ahead.
The aviation authority in a friend's current country of employment has started restricting all operating crew type ratings to their specific airlines. These are crew ratings or revalidations that have been completed generally with CAE, CTC and other places in Europe. The sim training is usually wet lease and the crew on their return to their various airlines within the country, are now receiving their licences (after they have been validated by the local aviation authority) with a restriction that states 'valid for [X airlines] operations only'.
As this seems to be unheard of, many people are wondering about the legality of the situation. Does anyone have any idea whatsoever about where information can be found regarding this type of restriction or is it best for those affected to seek legal advice?
Thank you
