Proposal Overview
  • Goals
  • Background
  • Methods
  • Conclusion
goals
Goals
  • Develop a model to optimize flight routes
    • Hypothesis: GIS-enabled routes increase mission effectiveness by significantly reducing susceptibility
  • Test the model results in relation to:
    • Experience
    • Expertise
    • Familiarity
    • Gender
    • Age
    • Terrain variability
background
Background
  • Survivability and susceptibility (Ball 2003)
    • PS = 1 – PK
    • PK = PH*PKH
    • PH = PA*PDA*PLD*PIL*PHI
  • Flight route optimization modeling
    • Operations research & stealth
    • Pekelsma 1988
  • Geography & mission planning tools
    • PFPS and FalconView (Bailey 2008)
  • Rotorcraft Noise Model
  • Behavioral geography
    • Visualization, orientation, relations(Golledge & Stimson 1997)

MethodsOverview
methods model temp altitude helicopter performance
MethodsModel: Temp., Altitude & Helicopter Performance

DA = PA + (120 TV)

DA = density altitude

PA = pressure altitude

120 = the change in DA for 1 degree Celsius deviation from standard temperature

TV = temperature variation from standard (15 degrees C at sea level)

= Outside Air Temperature (OAT) – {15 - [(PA in ft/1000 ft)*2]}

(HATS 1999: 2-17)
