Approval to display "TC" in front of initials.
First bestowed upon the replacement for the highly regarded Graham Jenkins. The inaugural award of the coveted TC title went to TCK. This was as a result of a particular pilot being hung out to dry by said TCK in a local v expat fracas. The said pilot was overheard referring to the then HOFO as T--- C--- K-----. The title stuck and grew in popularity until it became a symbol of all that is wrong with EK management.
The next to be awarded a lesser, but no less appropriate title was the not that much loved EGT. This new title, albeit of lower status than the coveted TC descriptor, was thought to be highly accurate and loosely affectionate due to it's congruence with aviation parlance.
Then, with the departure of TCK and the appointment of the aforementioned AS, and as a result of exemplary displays of contempt for his subordinates, AS was awarded the TC descriptor and anointed TCAS. The new HOFO enjoyed unparalleled status due to the combination of the previously described and highly coveted TC title combining with his initials, resulting in a very apt aviation acronym in TCAS. If sighted unexpectedly, the only appropriate response would be resolution advisory.
