Objectives - HTAWS

• Quantify the ability of the HTAWS to reduce
  incidents of Controlled Flight into Terrain
  (CFIT)
• Develop a test plan for the evaluation of the use
  of helicopter TAWS in day VFR operations
• Acquire access to TAWS-equipped helicopters
• Collect data from flight evaluation of the TAWS
  in various operational conditions
• Analyze the operational use of HTAWS for EMS ops
• Make preliminary recommendations for applications
  and training of HTAWS for EMS operators

5
Objectives - EVS

• Gather data to identify obstructions using EVS,
  during all phases of flight
• Quantify an individuals ability to identify the
  same objects and/or terrain with the unaided eye
• Analyze the operational use of EVS Systems for
  EMS operations
• Make preliminary recommendations for applications
  and training of EVS for EMS operators

6
Grant Modification

• Helicopter Operations Monitoring Program (HOMP)
• Appareo Systems ALERTS
• UND Schweizer 300 and later Bell 206
• All UND helicopters will be ALERTS equipped
• Reduction of flight events outside of preset
  limitations considered the boundaries of safety

ALERTS What Weve Learned So Far(In a Training
Environment)

• Originally designed for operational use
• Increasing training use
• Fort Rucker, Bristow Academy, UND, Bell
• Learning curve associated w/new technology
  (UND)
• Takes a while to gain acceptance and use

Grant Modification

• Helicopter TAWS scenario based testing using
  flight training devices (FTDs)
• Recreate accidents from the NTSB database
• Measuring pilot use of TAWS and outcome of flight

Scenarios/Routes

• NTSB accidents/incidents
• Have to be difficult enough to see if the HTAWS
  will result in an improvement
• Some routes may have no obstructions, obstacles,
  or terrain
• Pilots will fly the routes with/without HTAWS
