DETAILED REPORT ON THE B777-300ER:
The day before yesterday, on the Guarulhos-Confins route, I noticed that the Top OffC Climb (T/C) happens before the plane even arrives at cruise, and the Top Off Descent (TOD) happens even at takeoff, the plane descends normally when it arrives at true, but the warning follows the front of the plane until the end of the flight, this does not only happen with the 777, but with all available Boeings
