Gear Down Landing Rate of Climb
Boeing have in their B-777 QRH a Gear Down Rate of Climb Available; it shows the rate of climb with one engine inop, flaps at 30, speed Vref30 +5 Kts at a weight of 225 Tons.
This is the only Airplane that I have come across that have that information in their QRH and according to the information in the QRH explaining the Advisory Information it applies to an engine inoperative Autoland.
It puts a severe limitation on the use of flaps 30 with an engine shut down and I know of at least 2 other operators that do not apply that limitation
