FAA assigned take‐off slot due to en route wind conditions, route changes, or spacing requirements. Delays due to a missedslot, charge it to root cause. XB ‐Local Tower ATC: Delay holding for ATC or runway clearance which is withheld by the local FAA or OA tower. Flight crew will be notified. Delay Codes starting with 8 These Codes are used for Air Traffic Control (ATC) Restrictions (81-84) and Airport or Governmental Authorities caused delays. 81 ATC restriction en-route or capacity. 82 ATC restriction due to staff shortage or equipment failure en-route.

The Details tab shows the detailed information for one flight:

1 - Flight Identification

The query for which the Flight Details detached View is generated is reminded on top of the window:

Delay
  • ARCID: Aircraft identification.
  • ADEP: ICAO code of the aerodrome of departure.
  • IOBD: Initial Estimated Off-Block Date (Today or Yesterday)
  • IOBT: Initial Estimated Off-Block Time.
  • ADES: Aerodrome of Destination.
  • Filed ADES: only displayed for diverted flights. +
  • Proposal (Show Normal) or (Proposal exists - Show Proposal):
    • The text Proposal (Show Normal) is only visible in case the displayed flight is based on a Proposal flight plan.
      In such case, the text Show Normal implements a link to display the flight details view for this normal flight plan.
    • The text (Proposal exists - Show Proposal) is only visible in case the displayed flight is based on a Normal flight plan and a Proposal plan exists.
      This text implements a link to display the flight details view for this proposal flight plan.
Note: the Flight Identification is present on all the Flight Details windows, degardless of the tab selected.

8 - Regulation and Rerouting Information (group header Regulation)

  1. Rerouting warning message: The rerouting status and AOWIR possibilities.
    The rerouting status is only displayed if applicable. It is composed of a reason and a state.
    If the flight has been rerouted, the displayed rerouting reason may be:
    a) ATFM executed rerouting.
    b) ATFCM purpose RRP rerouting.
    c) ATC purpose RRP Rerouting.
    d) Aircraft Operator RRP.
    d) Flight efficiency RRP rerouting.
    d) STAM purpose RRP rerouting.
    d) CDR opportunity RRP rerouting.

When there is a rerouting reason, it is followed by one of these rerouting states:

Codes

Atc Slot Delay Codes Redeem

a) Produced for a valid rerouting going on, waiting to be realised by either an FPL or a CHG.
b) Executed when the rerouting has been processed.
c) Timed-out when no FPL/CHG was received on time.
d) Rejected for a rerouting proposal that has been rejected.
e) Revoked for a rerouting proposal has been revoked.
f) No-match when the message received did not match the proposal. Rerouting has been invalidated.

    To preserve readability and intuitive interpretation of this combined TTO Fix information, the following composing three data elements are concatenated using a fixed length format and separated by a blank character in order for each composing element to be well aligned with the content of the row above and beneath:
    (a) Location identification (point id possibly padded with blank characters to the right in order to obtain a fixed length of 5 characters)
    (b) A blank separator
    (c) Target time over (TTO) in hh:mm format
    (d) A blank separator
