Knowledge Based Functions in Aerospace Systems

The Pilot's Associate program has provided a series of
technology demonstrations of the potential of integrating
intelligent systems and artificial intelligence technology into
modern avionics systems. The Defense Advanced Research Projects
Agency and the United States Air Force have provided funding
and program management to determine the potential increases in
mission effectiveness from such a system. The Pilot's Associate
effort pursued by Lockheed and its partners has produced not
only prototypes for advanced systems, but also new insights
into the nature of the systems themselves as well as new
approaches for quickly producing software for these systems.
The rapid prototyping methods that have been utilized have also
provided the ultimate consumers - the pilots - with significant
awareness of the operation of the Pilot's Associate, and with
many opportunities to improve the requirements for such a
system. This paper describes the evolution of Lockheed's
Pilot's Associate System approach leading to the current system
configuration. Also described are some lessons learned from
managing a large software development team assembled to produce
an unprecedented system.
The aim of this paper is to describe the experience with the
problem of path generation and evaluation for a multitarget air
to ground planning system working in a limited geographic
scenario. The generation of a flight plan for a ground attack
mission in visual flight is a process that finds a path joining
a sequence of way points which connect the take off field with
the landing one through the planned targets of mission. A set
of constraints must be taken in account to build the paths that
will become flight plans. These constraints will be used in the
generations of plans together with a set of criteria for
evaluating the quality of the plans itself.
A knowledge-based cockpit assistant for IFR (Instrument Flight
Rules) operation is presented, aimed at improvement of
situation assessment and performance increase by computer aids
for flight planning and plan execution. Here, situation
assessment also includes monitbring of the pilot's own
activities. The modular system structure is described as well
as the individual system modules.
