Sharing the Skies - Harder than it Sounds

  • Background on "wildlife-strike prevention."
  • Bird Strikes have caused 4 fatal crashes, resulting in 8 casualties.
  • Each year ~45 strikes have damaged aircraft using Canadian Airports.
  • A further 180 "adverse effect events" (AEE) due to wildlife strikes or presence at airports (e.g., aborted takeoffs, rejected landings, etc.) all result in high-risk operations.
  • The need for proper wildlife management program and trained personnel at vulnerable airports.
  • The requirements for ATC to advise pilots of the hazard, its severity, and its location (in three dimensions) on the airport.
  • The inadequacies of "Passive Wildlife Management."
  • A robust wildlife management program requires a variety of audio/visual tools.
  • The need for Accurate Strike Recording (and how to keep them).

A Letter to the Loved Ones of my Friend, a Private Helicopter Pilot

  • A Letter from a Flying Instructor detailing the need to insure pilots keep their knowledge & skills current.
  • Excellent Hints & Reminders of critical factors to consider in insuring a safe flight.

Radium Luminous Devices

  • The dangers of Radium-Painted Aircraft Instruments.
  • Best ways to handle them.
  • Safe ways to dispose of them.

David Charles Abramson Memorial (DCAM) Award

  • Info on the annual award promoting flight safety by recognizing exceptional flight instructors in Canada.

Prospective Memory in the Cockpit

  • First in a series of in-depth reports from the Advanced Cognitive Engineering Laboratory.
  • "Prospective memory" supports your ability to carry out any behaviour that you, at one time in the past, planned to carry out in the future.
  • The four key elements of prospective memory:
    • Forming an intention,
    • Monitoring for cues that signal when the task is to be carried out.
    • Retrieving the details of the desired action.
    • Carrying out the intention.
  • Examples of "PM" failures in high-workload conditions.
  • Helpful ways of learning skills to help avoid PM failures.
