Recommendation: Simulations are needed to quantify TBO sensitivity to weather. This should include modeling or simulating the value of DST’s over a range of weather fidelity or outcomes. Recommendation: This also includes the simulation of weather probability translation upon TBO constructs (i.e., how each probability is translated and weighted within the DST components). Recommendation: The value of the integrated weather needs to be simulated and measured in terms of the metrics highlighted in 5.2.6 or from a cost/benefit perspective. In this regard, the value of continued in weather information fidelity needs to be modeled against ‘improvement’ real or perceived in DST outputs. ‘improvement’ Mixed Equipage Finding: There is a need to understand the operational impacts to users in mixed equipage scenarios. During any extended transition period it is anticipated that equipage and display standards – especially on the flight deck will evolve as market forces, rulemaking, and real or perceived – benefits are realized. This will mean that between, and even within, specific user groups (Part 121, 135, 91, etc.) will have varying capabilities with regard to airspace access, improved flight deck guidance (with or without integrated weather), and other evolving benefits of new or enhanced operations. Simulations could take into account varying display prototypes as well as the simulation of CDM between decision makers. It is important to understand, in a mixed equipage mode, what is required to maintain or achieve optimal trajectory and the consequences of deviation. Recommendation: Simulations of NAS users operating in a mixed equipage mode need to be conducted to determine consequences and relative sensitivity of continued mixed equipage towards achieving TBO objectives. The cost/benefit of optimal or minimal equipage needs to be simulated. Recommendation: Cost/Benefit Analysis of Forecasts Finding: In a related effort to TBO sensitivity to weather, the benefits of any additional costs must be clear to each stakeholder. Recommendation: There needs to be simulations performed that describe the cost to benefit of further improvements in weather products and forecasts beyond those so matched in informational integrity to TBO constructs. In this regard, there may be, for example, trending routines that could be designed that allow more frequent weather updates to be time-based averaged before integrating.
