  1. Measures and Models of Aviation Display Clutter June, 2009 NASA LaRC |NC State University |APTIMA

  2. Experiment Setup- Aircraft Familiarization -

  3. Simulator with an Advanced PFD • VISTAS (Visual Imaging Simulator for Transport Aircraft Systems) Simulator • No motion, ground-based simulator • Integrated PFD & ND with new display features • Enhanced Vision System (EVS) • Synthetic Vision System (SVS) • Flight pathway guidance (TUNNEL) • Embedded NAV – standard LOC and G/S features

  4. Advanced PFD Symbology Directed Altitude Directed Airspeed Actual Airspeed Current Altitude Directed Altitude Bug Directed Airspeed Bug Radar Altitude Vertical Speed Ind (VSI) DME

  5. ILS Indicator • Localizer and Glideslope deviation • No “Bends” • No “Lies” • “Raw Data”

  6. VSI Arrow Current Rate of Descent (Arrow) Commended Rate of Descent (Circle)

  7. Tunnel + FPV • TUNNEL • “Crow’s feet” define vertical and horizontal extent of desired path • Generated by computer database with GPS system • 600 ft wide by 350 ft tall: • “Linear” Deviation • Segments every 0.2 nm • Showing path 1 nm ahead Flight Path Vector (FPV) Indicates where aircraft will go

  8. ND Touchdown (TD) Point Course Line to TD Point Scale of Dotted Ring (NM)

  9. SVS (Synthetic Vision System) Terrain • Wireframe • GPS-based

  10. EVS (Enhaced Vision System) Terrain

  11. SVS / EVS

  12. Downward-looking View

  13. Side Stick Left + Right Button Aligns PFD waterline in the vertical center of the display Right Button Toggles PFD view between forward-looking and down-ward looking Left Button Re-centers flight symbology on the PFD Hat-Switch Controls rate of descent with fore and aft inputs. Each click equals 30 fpm

  14. Experiment Setup- Scenario Familiarization -

  15. Flight Scenario Overview • ILS Approach and landing at a desert landing site • Consists with descending and hovering • Hand-flown with autothrottle • Pilot commands desired vertical speed with hat-switch on stick • Auto throttle adjust engine thrust to achieve vertical speed • Pilot adjusts airspeed with pitch (with fore & after) • Begins 7NM inbound to helipad • Ends with landing decision • Night/IMC: • Weather near or below minimums • Dust near ground • No approach lights or lighting of TD • Go-around or landing performance will not actually be measured

  16. Descent Phase (3 deg glide path) Begin 250 KIAS 2460 MSL/HAT (1680 AGL) Stop and resume at random point 0 KIAS 250 ft MSL (250 ft HAT) Hover Phase Visual contact with the ground -Landing decision 100 ft MSL (100 ft HAT) 7NM End

  17. Roles and Responsibilities • Captain • Hand flying with sidestick (Hdot + Manual mode) • Verbalize all decisions at decision height. • First Officer (FO) • Handle ATC communication • Provide callouts as briefed (altitude) • Will confirm objects in sight (visually) • Will answer queries and confirm settings, procedures, etc.
