DURATION EXTREMES
---------------------------------------------
LONGEST CONTINUOUS CONFIG:
SUN12 2350 → TUE14 1345 = 37:55
CONFIG: 22L/22R (SOUTHWEST FLOW HOLD)

SHORTEST TRANSITIONS:
04R/04L → 13L/13R = 03:55
13L/13R → 22L/22R = 04:45
22L/22R → 31R/31L = 04:50

---------------------------------------------
OBSERVED PATTERN SUMMARY
---------------------------------------------
• Initial full directional sweep:
  31 → 04 → 13 → 22
  → Consistent with gradual wind rotation

• Mid-period behavior:
  Alternation between 13s and 22s
  → Indicates variable but generally southerly flow

• Late-period behavior:
  Increased use of 22s with brief reversals (31 / 04)
  → Suggests temporary stabilization with passing disturbances

---------------------------------------------
RUNWAY USAGE INSIGHTS
---------------------------------------------
22L/22R:
- Most frequently sustained configuration
- Longest continuous usage period
- Associated with southwest flow conditions

13L/13R:
- Common intermediate configuration
- Often appears during transitions between flow directions

31R/31L:
- Used during northerly flow periods
- Typically appears during directional reversals

04R/04L:
- Least utilized in this dataset
- Short-duration usage during rapid wind shifts

---------------------------------------------
INTERPRETATION
---------------------------------------------
This dataset reflects normal JFK operational behavior driven by:
- Wind direction changes
- Passing weather systems
- Air traffic demand

No fixed “cycle” or repeating phase structure is implied.
Observed patterns are specific to this time window.

---------------------------------------------
FINAL SUMMARY
---------------------------------------------
Dominant configuration during analysis period:
→ 22L/22R (Southwest flow bias)

Overall pattern:
→ Directional rotation followed by partial stabilization
