• Key point
• Keep airspace as free as possible for Sport
  aircraft

• IGC position
• Where restrictions apply, work to gain airspace
  access
• by
• 1. Use of low-cost avionics designed for Sport
  aircraft
• (not expensive avionics designed for airliners)
• to negotiate this we must have some people who
• 2. Understand the technology

SatNav systems Keep under review GPS,
Galileo, GLONASS, Beidou/Compass Understand the
technology Accuracy, area enhancements (SBAS,
WAAS, EGNOS, see CANS Glossary) Use existing
expertise within FAI Expertise of IGC ANDS GFA

Radar Transponders (for instance Mode S -
Selective) - avoid if possible - but
recognise existence of Transponder Mandatory
Zones (TMZ) - low cost Mode S versions if
forced to use - Battery power allowed for

Traffic Alert Systems (collision
avoidance) Radar Transponder-based system -
TCAS (Traffic Alert Collision Avoidance
System) designed for one-on-one encounter as in
Überlingen accident but not designed for groups
of aircraft (gaggles of gliders, hang-
para-gliders, microlights etc)

Traffic Alert Systems GPS-based - ADS-B
and Flarm Flight Alarm (Flarm) and similar
now in extensive use Swiss Flarm - over
10,000 sold, IGC version available for
recording Short range/low power - can use
non-air frequency Other products - OzFlarm -
DSX Traffic Avoid system Need for stable R/T
protocol for position data (Italy paper to IGC
2008) Future compatibility with ADS-B Future
long range Flarm-type system ADS-B at low cost

IGC Summary 1. CANS is important area for IGC
and FAI literally vital for some sport
aviation activities 2. Utilise existing
expertise in IGC and FAI 3. Vigilance needed to
preserve airspace 4. Future avionics
ADS-B in particular ( son of Flarm )
but designed for sport aircraft, not
airliners. Battery power Need
to work with ICAO regulators for
avionics suitable for sport aircraft
