Fortunately the court, where he is tried for his misdemeanour, cannot also 'sack' him, it has to apply it's own sanction, which cannot fully take into account the likelihood of his employer's actions (that would be in the realms of fortune telling.) I say fortunately because any other course would be totalitarian.
I agree that losing his job as a pilot, should it happen, is more than enough of a sanction and deterrent. If he doesn't lose his employment there has to be some form of sentence. It's all very sad really.
