I am just starting a 7 day trip, the first day is now done. I had a chance to review our MEL
on the issue of transponders and TCAS.
does not allow dispatch with both transponders inop. Simply stated, you just can't go.
TCAS can be inop provided you are not flying into RVSM airspace. Practical application: You can't go.
As far as the MEL
being relaxed, that process is not a quick process. Initially, the courtry's regulatory body, ie., FAA/CAA approves the MEL
. To have something "relaxed" you have to now re-write the MEL
and submit it to the CAA/FAA. As with any regulatory body, the wheels don't move quick.
