Advanced Navigation Research in a Helicopter
Training Program

• Primary Researcher Leslie Martin
• Research Assistant Amanda Kolling

2
Purpose of the Study

• Determine how accurately pilots can fly PVFR
  routes by collecting real-time flight data on the
  campus of UND with the various factors
  considered
• Degree of turn
• Leg lengths
• Flight Conditions VFR, MVFR, IFR, and winds
• Aircraft Equipment

3
UND Provides the Necessary Environment

• Total of Seven Helicopters
• Two Bell 206 Jet Rangers equipped with Garmin
  480s
• Five Schweitzer 300s equipped with Garmin 430s
• Varying degree of pilot experience from Student
  Pilots to Commercial Pilots to CFIs

Cockpits

• 300s

• 206s

6
ADS-B

• Automatic Dependent Surveillance Broadcast
• Two antennas in ND Grand Forks and Devils Lake
• All of the helicopters are ADS-B equipped

7
Study Design

• Series of routes have been created for transition
  to and from the helicopter practice areas that
  surround the GFK Airport
• ADS-B, CRABS, and Targets will be used to collect
  data
• Pilots will fly the various routes with GPS
  serving as primary guidance
• Questionnaires completed by the pilots will be
  used to determine the following
• Pilot experience level
• Flight Conditions Night, Day, VFR, MVFR, and
  simulated IFR
• Deviations from routes caused by ATC

• The following is one of the routes that have been
  created, tested, and loaded into the GPS databases

Data Sheet

• Filled out by the pilots after each flight
• Lets us know if they flew a Departure or Arrival
  and if so, which one, along with other pertinent
  information
• This information is collected weekly

10
CRABS

• Comprehensive Real-time Analysis Broadcast System
• Software that enables us to capture and record
  flight data of all ADS-B equipped aircraft

11
CRABS Extracted Tracks
12
Targets

• Importing data from CRABS into Targets to find
  out the amount of deviations that occur

13
Current Status of Project

• Pilots are flying the routes whenever possible on
  their flights
• They turn in a questionnaire after every flight
  that contains data appropriate to the route they
  flew
• The questionnaires are then compared to the data
  recorded by CRABS

14
Current Status of Project

• The CRABS data is imported to Targets
• Deviations are being measured and recorded into
  an excel spreadsheet
