From the 787 QRH: “To determine the energy per brake absorbed during landing, enter the Event Adjusted Brake Energy table (Table 2) for no reverse thrust or 2 engine reverse thrust with the reference brake energy per brake and the type of braking used during landing (Max Manual, Max Auto, or Autobrake).”
Not saying you’re wrong but I can’t see a reference to reversers “unlocked”? I was taught that our SOP of reverse idle is not covered by either of the tables.
Do you have a reference please?
