Aviation Institute During research for Summit Program : notable difference between international and domestic operations International: large-jet commercial operations Domestic: significant non-large-jet operations aviation safety priorities seemed biased towards international large-jet commercial operations Are causal factors and accident characteristics transferable between segments of aviations?

Emerging Aviation Markets Academic & industry literature: Predictions of significant increases in utility of community airports by regional, commuter, air taxi, corporate and private aviation operators. Enabling technologies micro-jets Low cost (relatively) Anywhere, anytime mobility April 17-21 2005, Vancouver Canada. 2-9
Emerging Aviation Markets Independent of allure; future of the private commuter aircraft likely extremely limited April 17-21 2005, Vancouver Canada. 2-10
Emerging Aviation Markets Aircraft with reduced price structure: micro-jet 1/4 to 1/3 cost of contemporary 4-6 passenger jet aircraft Eclipse 500 (and others) affords opportunity for Increasing business & corporate utilization Unscheduled air taxi operations Private operations April 17-21 2005, Vancouver Canada. 2-11
Risk Exposure More people flying to more places on smaller and more frequent flights into community airports with no tradition of high volume commercial operations Risk of being involved in aviation accident based on exposure: One component being number of operations Passenger Resident of community surrounding airport April 17-21 2005, Vancouver Canada. 2-12
Individual vs community risk exposure 8 7 Community: 100,000 operatio likely number of accidents 6 5 4 3 2 specific aircraft ~ 100 operations Community: ~ 50,000 operations 1 0 0 20000 40000 60000 80000 100000 exposure April 17-21 2005, Vancouver Canada. 2-13
Estimating Community Risk Sometimes aircraft miss the tarmac (and the whole airport), inducing risk on surrounding community Boeing summary as an estimator: Approximately 50% accidents during non-landing phase of flight Validate with Virginia Part 91 accident locations based on phase of flight April 17-21 2005, Vancouver Canada. 2-14
Community Risk State of Virginia Part 91 aviation accident location by "phase of flight": 1993-2003 47% all accident occur: non-landing phases of flight 34% all accidents: non-landing & non-takeoff 23% of all accident are fatal 11% are serious 69% fatal accidents occur during non-landing 51% fatal accidents: non-landing & non-takeoff 47% of fatal and serious accidents: non-landing & non-takeoff source: NASDAC database April 17-21 2005, Vancouver Canada. 2-15
Community Risk ~ 50% aviation accidents occur off airport property Back of the envelope calculation: Estimate community risk based on current accident rates and forecast data Problem: other components of exposure: Accident rates function of: type of aircraft type of operation April 17-21 2005, Vancouver Canada. 2-16
