Now why do airlines do that? Why? Why deviate from the manufacturer's guidelines? Too clever by half? Gilding the lily? Sometimes for better, sometimes for worse and ESPECIALLY airlines who refuse ENGLISH as the norm!! Oui, l'exception culturel...courtesy of la Loi Toubon.
Diammetrically-opposed FCOMs between AF and IT pre-merger...yes, they didn't quite agree on how to fly the A320...
Now, just look at AF and LX FCOMs on UAS...vive la différence...
Mais nom de bleu, je
préfère les suisses même s'ils se lèvent tôt mais se réveillent tard! (for God's sake, I prefer the Swiss even if the rise early but get up late!).
Ah, LX bans EXPED for example by removing P/B and placing a mini-placard maybe because they're anally-retentative.
Somehow, it's more on Airbus that FCOMs deviate compared with Boeing.
