Hello, testing the BB757, I came across this issue with the 757/767 takeoff performance calculator in SimBrief. I believe Jason is already going to relay this, but figured I would make a post as well, just in case.
Anyways, Would it be possible to remove the options for TO1 & TO2 in the SimBrief Takeoff performance calculator. Unlike the 737/777, on the 757/767 TO1 and TO2 are NOT fixed derates. Rather, they’re all the exact same as TO just with either CLB1 or CLB2 pre-armed.
Currently, if one selects Optimum and SimBrief spits out a TO2, SimBrief is falsely applying an 80% fixed derate to the Takeoff performance numbers. As you can imagine, this is going to affect distance calculations, runway limits, etc. So, considering that there is absolutely no difference (EPR-wise) between TO, TO1, and TO2 in the 757/767, it would be best if those options were just removed altogether, since they will do nothing but throw off unsuspecting users.
