1. ASAP—Problem Statement
Create a Graphical User Interface to:
Examine HQs re ADS-33E-PRF rqts
Call out significant features, cautions,
Interface with other analysis tools
Easily input variety of data formats, sources
ASAP refers to “ADS-33 Software Assistance Package,” a graphical user interface intended to aid a user of ADS-33E-PRF in the analysis and interpretation of helicopter handling qualities.

2. FlightLab Pilot Models
ART SBIR for Navair
H-60, H-53 helo models
RHE using Task-Pilot-Vehicle (TPV) approach to provide pilot models for several tasks
ADS-33 maneuvers & shipboard ops
TPV modeling will be available to Navair
FlightLab is a widely-used rotorcraft math model development package designed and marketed by Advanced Rotorcraft Technology, Inc., of Mountain View, CA.
ART is currently engaged in a Phase II SBIR for Navair to provide helicopter math models of H-60 and H-53 aircraft.
One part of this effort is the addition of a pilot model to FlightLab capable of simulating two ADS-33 demonstration maneuvers and two DDG shipboard tasks.
RHE is developing the FlightLab pilot models using the TPV model approach developed previously for the U.S. Army and Navair under SBIR efforts.

Demo of TPV for FlightLab
This is demonstration of the TPV model designed to simulate the ADS-33E Depart/Abort maneuver using a CH-53 aircraft model.
The TPV model is based on validation data from VMS experiments conducted earlier this year by ART and Hoh Aeronautics.
The example used RHE pilot model development tools, including use of FlightGear software to provide the virtual reality visual presentation.

3. In-House Pilot Model Tools
Robert Heffley Engineering is currently developing a comprehensive pilot model development capability based on the Task-Pilot-Vehicle (TPV) modeling paradigm.
The TPV models operate in a Matlab/Simulink environment along with FlightGear to provide a visual presentation.
The TPV and FlightGear models are launched from the ‘tpv’ GUI. Task and pilot parameters are carefully partitioned and easily adjusted while viewing the TPV model performance against manned flight or simulation validation data.

In-House Pilot Model Tools
Purpose to support Task-Pilot-Vehicle applications
Matlab/Simulink-based models
Range of vehicle model forms
Tasks easily modeled from sources
Pilot parameter adjustment using classical control methods
FlightGear provides TPV visualization
These are some of the features of the RHE pilot model development tools now under construction.
