  1. Departure Clearance Health Monitoring Report and Analysis Ryan Hale, Greg Saccone, and Rob Mead Advanced Air Traffic Management Boeing Research & Technology

  2. DCL Report Logic • Look for FPL with “FRCDCL” (case sensitive) within the first 22 characters of the RMK field (departure airport and airline configurable) • Group eligible flights by Departure, Origin, Flight ID • Use FPL departure times and eet to group messages into a flight • Flag DM25 requests that aren’t associated with an eligible FPL • Mark eligible flights that did not perform a logon and encountered a tail swap as not eligible • Look for AFN CON • Look for AFN ACK from EWRCLYA and MEMCLYA (configurable) • 11/5 - Ignore UPS Test Flights with Flight Number 99XX in 620 or 622 message • Look for CC1 • Until UM161 or a DR1 is received: • Look for DM25 • Look for Standby Uplink • Look for a DCL referencing the DM25 in the form of a UM79, UM80, UM83, or any other uplink. • If a UM79, UM80, or UM83 is uplinked and does not reference an unanswered DM25, an error will be identified • If any uplink indicates an “error”, it will be identified even if it does not reference a DM25 • Look for Standby Downlink • Look for WILCO, ROGER, UNABLE, or DM62 Downlinks • DM62 will be reported as an error response

  13. Definitions • Eligible Flight – An FPL that has “FRC DCL” (case sensitive) within the first 22 characters of the RMK field • Initial Revised • Initial clearance with route clearance • Could be a forced initial clearance • Qualification of what a revised clearance should be for stats purposes to be discussed as part of the requirements catalog for stats • Average Round Trip Time • The amount of time elapsed, in seconds, from the time the DCL uplink is sent to the time the Wilco downlink is received • The message times are the times that the messages are received by Boeing
