  • 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)

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)
