Preventing Airspace Infringement Class of
Airspace Crew Awareness Limits

• The Midair Collision Case (A320/Glider)
• Type of airspace successively crossed during A320
  arrival
• From cruize to initial descent class A
  controlled airspace
• Descending below FL195 class D controlled
  airspace
• At 15h38, 38 Nm from destination, passing FL115
  class G uncontrolled airspace corresponding to
  LF-R108E2 regulated zone (inactive at this time)
• The mid air collision occurred at 15h40 at FL80
  in this class G airspace.
• Minutes after the collision class D controlled
  airspace S/CTA Rhône 3
• Descending through 5700 ft class E controlled
  airspace airport TMA 4
• At about 4900 ft class D, destination airport
  TMA 3
• Then the A320 flew until landing in this class D
  controlled airspace while entering successively
  the TMA 1 then CTR of destination airport.
• Difficult to be constantly aware of the type of
  airspaces crossed while preparing for an approach
  and watching outside in compliance with the see
  and avoid rule ?

Preventing Airspace Infringement Some Incident,
Accident

• Infringement not only for G.Aviation
• Early descent Scenario
• Aircraft cleared too soon to descent to final
  descent altitude
• Visual approach scenario
• Leading to flight path conflicting with secondary
  ruwnay circuit dedicated to GA
• Crew not always aware of mixed IFR/VFR trafic
  airspace
•  Scenic  arrival and departure
•  Table mountain  in Cape town
• Training flight
• Airport or runway confusion

Preventing Airspace Infringement Some Type of
Threats for Airlines Operators

• Gliders
• Light VFR aircraft
• Weather balloons
• Hot air balloon
• Kites
• Para jumping
• Drone

12
Preventing Airspace Infringement Contribution of
Operators

• Contribution of airlines
• Better crew reporting (accuracy, relevancy)
• Better Information Sharing
• Departure and approach trajectory modification
• Lobbying airline pilot for influencing GA
  association they may belong
• Increasing crew awareness about mid air collision
  risk on some airspace
• Others

Preventing Airspace Infringement Threat and
Error Management perspective

• Threat are situations external to the flight
  deck, that must be managed by the cockpit crew
  during normal, everyday flights. Such events
  increase the operational complexity of flight and
  pose a safety risk to the flight at some level.
• Error are actions or inactions by the crew that
  lead to deviations from organisational or flight
  crew intentions or expectations. Errors in the
  operational context tend to reduce the margin of
  safety and increase the probability of accidents
  or incidents
