Too bad many pilots don't know this and think engine falls off the pylon after using TOGA for 5 min and 1 second.
As you say the limitation is only paperwork & money, and only applies if at full power TOGA.
Let's add this to the "I didn't know that" box. And that box is bigger than many might believe: the more so because Flt Ops manuals are diluted and TR syllabi more limited. Once never learned it is easy to stay never learned. On a good day you use only a small % of a/c knowledge, and you have enough. On an average day much the same. On a bad hair day you might need more and today's apprenticeship is considerably reduced in many ways; knowledge & demonstration by the more learned.
