OOOI Data refers to times of the actual aircraft movements of Gate Out, Wheels Off, Wheels On, and Gate In. Starting in the year 2000, OOOI data were provided for a subset of carriers by ARINC (a private aviation communications company) on a next day basis, and for DOT's ASQP carriers on a monthly basis. In April 2015 additional carriers began providing next day OOOI through TFMS, and starting in FY16, the FAA began to receive OOOI data provided by the OAG for nearly all commercial carriers with flights to and from the U.S. The ARINC feed was discontinued on October 3, 2016. In addition, since October 2012, CountOps Threshold Crossing Times, which are within seconds of the Wheels Off and Wheels On times, have been used to populate the Wheels Off and Wheels On times on a next day basis when no OOOI data are available. CountOps is an automated source of departure and arrival counts for Operations Network (OPSNET).
These actual aircraft movement times are the basis for many statistics throughout ASPM. When OOOI times are not available, they are estimated. For more information on estimation techniques, see ASPM: Estimation Techniques.
Domestic passenger carriers which report OOOI data for the majority of their flights are referred to as ASPM carriers, and can be used for carrier-specific analysis of on-time performance and other metrics. Air Canada, UPS, and FedEx are also considered ASPM carriers, although they only report OOOI for a subset of their flights. There are approximately 40 ASPM_Carriers.
