Thanks for your input guys it makes sense.I totally agree to treat the failure independantly as no dispatch like stated in the MEL.Doing otherwise is a kind of arrangement not so compatible with aviation. But similarly when RA1 is inop which is a no go item , how would you see the swapping over? Legal or not?If RA2 replaces RA1 , now RA1 is working , would you accept such swapping not written in the holy books to dispatch the aircraft?If the tachymeter is so important that even a deactivated brake could not work without ,MMEL should state it as one of the condition to dispatch the aircraft with one brake deactivated. " brakes inop---condition of dispach tachymeter operative" or is it a miss?
Likwise if nothing is written about the swapping does that mean that you can or cannot do it?
