COLLISION AVOIDANCE A Different Perspective
What Different Perspective? • No Boring Statistics ! • No Boring Discussion on the Limitations of the Human Eye ! • No “How to Scan for Traffic” Sermon
The Goals • Define the Problem • Offer Solutions
BUT FIRST . . . . . . a little review !
The Holy Grail FAR 91 . 113 . . . Vigilance shall be maintained by each person operating an aircraft so as to see and avoid other aircraft.
THE CHALLENGE • As the National Airspace System becomes increasingly complex, the threat of mid-air collisions involving general aviation recreational aircraft will increase ! • Mid-air collisions usually involve fatalities - there are no fender-benders in the air !
Interesting Statistics ! 1991 - 1996 79 Mid-air collisions involving general aviation aircraft !
DOES NOT INCLUDE - • FAR Part 121 / 135 Aircraft • Military Aircraft • Public Use Aircraft
SAFER SKIESA Focused Agenda • Pilot Judgment & Decision-making • Loss of Aircraft Control • Weather Factors • Survivability • Collision Avoidance
INTERESTINGHUMAN LIMITATIONS • Empty-Field Myopia • Blind Spots • Fixation / Distractions
What does all of this mean ? • Because of physical limitations and the increasingly complex nature of our airspace system, the potential for a mid-air collision is very real and will remain a serious threat to general aviation safety !
The Strategy -The Three W’s WHEN ? WHERE ? WHAT ?
THE STRATEGY ! • WHEN are mid-air collisions most likely to occur ? • WHERE is the potential for a mid- air collision the greatest ? • WHAT can the pilot do to prevent or minimize this threat ?
WHEN ? • VFR WEATHER • BELOW 3,000 FEET AGL • WITHIN 10 MILES OF DEPARTURE AIRPORT • WEEKENDS
WHERE ? • WITHIN 10 MILES OF NON-TOWER AIRPORTS • TRANSITION TO/FROM THE TRAFFIC PATTERN • PRIMARILY IN THE TRAFFIC PATTERN !
Everything You Always Wanted to Know About the Traffic Pattern, but . . . • FAR 91 . 113 • FAR 91 . 126 • FAR 91 . 127 • AIM
FAR 91 . 126 When approaching to land at an airport without an operating control tower . . . each pilot of an airplane must make all turns of that airplane to the left [ unless otherwise designated ].
FAR 91 . 127 When operating in the vicinity of an airport in Class E airspace, comply with FAR 91.126
Furthermore . . . Aeronautical Information Manual Chapter 4 Section 3 Airport Operations FAA Advisory Circular 91-66A Recommended Standard Traffic Patterns and Practices For Operations At Airports Without Operating Control Towers
CONFUSING ? You Bet !
SURVIVAL STRATEGIESThe “WHAT” Know where the traffic is ! Airports Victor Airways MTRs
SURVIVAL STRATEGIESThe Sequel ! Know where the potential for conflict is the greatest ! Traffic Pattern (Specifically Final Approach)
The TRAFFICPattern ! • Downwind Leg - 2% • Base Leg - 18% • Final Approach - 80%
(F)USTALL • Look out - and LOOK OUT! • Where & When to ESPECIALLY look? • Constantly checking for traffic should be a habit - a way of life. Without it you may not have a life…!
Entry Downwind Base Final Critical ‘Check For Traffic’ Points
SURVIVAL STRATEGIESPart Three RADIOS - use them or lose them ! Report positions frequently, and accurately, when operating in the vicinity of a non-tower airport.
SURVIVAL STRATEGIESThe Conclusion “See and Avoid” is more than a regulation, It is an Attitude !
It’s all up to you! • Be aware - responsibility for mid-air collision avoidance is in YOUR hands! • ‘ SEE AND BE SEEN’! • Check your attitude - no-one is invulnerable. Thanks for listening - any questions…? Lou Frank
