3. A2000 FAA-Eurocontrol sponsored Technical Interchange Meeting (TIM) on intent information included a recommendation in its outbriefing to, "Study the relationships between aircraft control loops and intent parameters."18Thisrecommendation is important, in part, because the amount of intent information available for data exchange depends strongly on the transmitting aircraft's current control state and equipment. These relationships were evaluated in several Boeing 777 simulator sessions and through a review of Airbus vertical flight modes.19The TSandTCreportsare designedtotake advantage of intent information available when aircraft are operated in either simple or complex control states.
4. Both the command and planned trajectories may provide useful information for separation assurance and flow management applications. The command trajectory, however, is considered to represent the aircraft's current intent and therefore has broadcast priority over planned TCPs. This strategy was also explicitly expressed at the 2000 Intent TIM.21The TC report structure enables the receiving system to clearly distinguish between the commandandplannedtrajectories.
