  • Conundrum A question or problem having only a conjectural answer An intricate and difficult problem
  • Performance-based operations depends on capability and performance of many aspects of a complex system involving people, procedures, technical elements, and different functionality. One of the objectives in transitioning to performance-based operations is to build on what exists in aircraft and in air traffic service provision to optimize operational benefits. Another objective is to exploit modern technology by establishing standards that define the “minimum acceptable” capability and performance required for an intended operation and independent of any particular technology.
  • e.g., satellite data link, that is better than the communications equipment required for dispatch, e.g., high frequency (HF) voice; such as 100 NM lateral/10 minute longitudinal separations, 50NM lateral/50NM longitudinal (50/50) separations, and 30NM lateral/30NM longitudinal (30/30) separations, in the same airspace, and the use of those services is predicated on operator eligibility and aircraft capability and performance; such as satellite, to provide the preferred, primary, normal, or replacement means for air traffic control (ATC) communications, and the communication equipment required for dispatch does not have the performance to execute contingency procedures needed in the event the primary or normal means fails, e.g., HF voice regression; such as FANS 1/A-based ground system implementations providing ATC data communications in common airspace to FANS 1/A aircraft and ATN aircraft; and e.g., HF data link (HFDL) may be suitable in airspace with 100 NM lateral/10 minute longitudinal separations, but not suitable in airspace with 30/30 separations
  • I would like to introduce a new activity under the auspices of the Performance-based operations Aviation Rulemaking Committee (PARC). This new activity will be performed by the Communications Working Group. Before I talk about the Communications Working Group, I want to say just a few words about the PARC itself. The PARC [read sub-bullets] Optional: You may have heard of the Terminal Area Operations Aviation Rulemaking Committee (TAOARC). The TAOARC was renamed to the PARC in February of 2004.
