I have been hired by a Part 121 airline who will award me a restricted ATP and type rating during training. My certificate now is a commercial pilot with AMEL with a center thrust limitation. The airline is telling me I have to have the restriction removed before beginning training because they aren't able to. Can anyone explain why they wouldn't be able to remove the restriction? Also, is there a reason I wouldn't be able to fly with them with the multi-engine ATP and type rating that I'll receive during training even with the restriction on my commercial? Thanks.
