Determination of Historics and Monthly data Release to NRTCAB

  • Slots are eligible for historical precedence when a series of slots cleared by JSC have been operated by that air carrier for at least 80% of the time during the scheduling period (WSG 8.6 & 8.7).
  • Further to the guidelines of WSG, following local rules apply for the determination of which historical slots;
  • Slots held on file by JSC before monthly data release to NRTCAB will be used as the basis for determination of historics.

(Example of Calculation of historical slots)

→ 2 flights cancellation at JSC      <22-2=20>
→ 5 flights cancellation at NRTCAB    <20-0=20>
15 Operation<22-2-5> ÷20Flights<22-2> filed at JSC = 75%
