Additionally, computation of repeated-measures ANOVAs with three factors (i.e., priority-flight request, traffic volume, and time slot) indicated an interaction effect between the time-slot and priority-flight request factors that was highly significant for the lg(LF/HF) ratio (F(1, 20) = 22.184, p ≤ .001, η 2 = 0.526) but failed to reach the significance level for the lg(MF/HF) ratio (F(1, 20) = 3.633, p = .071, η 2 = 0.154).
