“…In order to address trajectory uncertainty, work conducted by Paglione, et al [13], and Bronsvoort, et al [14], demonstrated that ground-based trajectory generation systems can benefit significantly from using data from the aircraft's FMS-generated trajectory (e.g., via the EPP message). Bronsvoort, et al [10], describe two approaches for using such information.…”

A critical component of Trajectory-Based Operations is the ability for a consistent and accurate 4-dimensional trajectory to be shared and synchronized between airborne and ground systems as well as amongst various ground automation systems. The Aeronautical Telecommunication Network-Baseline 2 standard defines the Extended Projected Profile (EPP) trajectory that can be sent via Automatic Dependent Surveillance-Contract from an aircraft to ground automation. The EPP trajectory message contains a representation of the reference trajectory from an aircraft's Flight Management System (FMS). In this work, a set of scenarios were run in a medium-fidelity aircraft and FMS simulation to perform an initial characterization of EPP trajectory errors under a given set of conditions. The parameters investigated were the route length, route type, wind magnitude error, wind direction error, and with and without a required time-of-arrival constraint.

“…Alwi and Edwards 4 proposed a novel nonlinear fault-tolerant scheme for longitudinal control of an aircraft system, comprising an integral sliding mode control allocation scheme and a backstepping structure. Bronsvoort et al 5 illustrated that inaccurate longitudinal aircraft intent and resulting excessive prediction errors are evident. Stojiljkovic et al 6 presented an application of the root locus technique for the design of a feedback control system of an F-104A aircraft.…”

Aircraft longitudinal dynamics is approximated by short-time mode and phugoid mode from experience. In this article, a rigorous mathematical method is provided based on the singular perturbation theory to deal with this decoupling problem. The longitudinal decoupling and singular perturbation are first introduced. The longitudinal equations are normalized and transformed into a canonical form to extract the perturbation coefficient. Thus, the entire dynamics model is partitioned into boundary-layer equations and slow equations according to singular perturbation theory, which presents a proof to the experience method. The simulation results show that the proposed decoupling approach is sufficiently excellent to approximate the underlying model both in time domain and frequency domain.

“…Ground-based trajectory predictors (TPs) often lack critical information required to predict an aircraft's future trajectory [2], or the information is not up to date due to clearances issued by air traffic control (ATC) that have not been entered into the ground-based system [3].…”
