On some types, the brakes affect the tailwind limits and one manufacturer may have a higher limit than another. Aircraft which appear identical can have numerous differences under the skin as I’ve found out when engineers tell me the flight control computers are incompatible and we can’t simply swap from one aircraft to another.
I’ve seen A320s with tailwind limits as follows for take off and landing: 10/10, 15/15, 15/10 and 10/15 depending on the S/N.
