Abstract
Continuous Descent Operations (CDO) with Con-
trolled Times of Arrival (CTA) at one or several metering fixes
could enable environmentally friendly procedures without com-
promising airspace capacity. Extending the current capabilities
of state-of-the-art Flight Management Systems (FMS), the Time
and Energy Managed Operations (TEMO) concept is able to
generate optimal descent trajectories with an improved planning
and guidance strategy to meet CTA. The primary aim of this
paper is to compare the performances of TEMO (in terms of fuel
consumption and time error) with respect to a typical FMS, that
is an FMS without re-planning mechanism during descent based
on time or altitude errors. The comparison is performed through
simulation, using an A320-alike simulation model and considering
several scenarios in presence of CTA and wind uncertainties.
Results show that TEMO is capable of guiding the aircraft
along a minimum fuel trajectory still complying with a CTA,
even if significant wind prediction errors are present. For a
same scenario, a typical FMS without re-planning capabilities or
tactical time-error nulling mechanism during the descent, would
miss the CTA in most cases.
