Abstract :
This paper presents the concept and design of an on-board decision support tool for planning energy recovery strategies in time-constrained descents. The energy recovery problem is formulated as a parameter optimization problem that can be solved using static optimization techniques. The recovery advisory generated by the tool enables the pilot to capture the altitude and speed targets using a combination of adjustments that alter the aircraft power along an updated lateral path. Preliminary simulations show that a feasible recovery solution is always identified and large energy deviations can be recovered with minimal violation of arrival time at the fix.
