Rodeo Posted February 18, 2022 Report Share Posted February 18, 2022 Example, for an OAT of +5°C: assumed temperature of +45°C already gives apparent "maximum reduction" for FLEX (N1 target 85.0%) increasing the assumed temperature to +50°C gives the same N1 target of 85.0% as the above… but V-speeds (here, V1) and especially required takeoff distance differ: …that over 100m of runway, which seems like a lot if it were caused by e.g. rounding (say, N1 target of 85.04% at FLEX 45 vs. 84.96% at FLEX 50)? It kind of looks like, possibly, the assumed temperature of +50°C initially results in an N1 target lower than 85.0 which then gets sanitized to a minimum target, but TOFL and V-speeds are based on the invisible, unbounded N1 target instead?
