Workload Intensity vs Next-Day Recovery
Blue bars = landings per flight day. Red bars = high-workload days (≥5 landings).
Green line = next-day recovery score. Red dots = days where recovery fell below the
elevated-risk threshold of 50.

Recovery Calendar: Fatigue Accumulation by Week
Each cell = average recovery score for that day of week in that calendar week.
Red = elevated risk (<50), amber = caution (50–65), green = clean (>80).

Landing Count vs Next-Day Recovery — OLS Trendline
Each point = one flight day. Colour = next-day recovery (red <50, amber 50–65, green >65).
Dashed red line = OLS trendline. Hover any point for date and same-day recovery.
Note: result does not reach conventional significance (p=0.084, r²=0.068).
