■ Accident Rate Fatality Rate

As we have seen, even within Europe, scheduled and business aviation fly different distances to and from different airports, so a perfectly-matched comparison of the safety records of the two is not possible. For guidance, a comparison has been made using statistics per depar-ture, in order to reduce the differences in typical operating distances between the two segments. The results are shown in Figure 34 and indicate that globally, business aviation operations by jet could improve their record further, if scheduled jet operations are used as a benchmark.

Since business aviation is typically short-range, say 500km (see section 15), it is illuminating to compare accident rates with that of motorway and rail travel, which at that distance could be viable alternatives. In Europe, rates are variable, but on average motorway travel suffers 7.5 fatalities per billion passenger kilometres travelled19 and the rate for rail travellers is around 0.9 fatalities per billion passenger kilometres. Making a low assumption of four passengers per aircraft and using the median business jet flight length of 600km, the 0.22 fatality rate for business aviation jet departures worldwide (Figure 34) approximates to one fatality per billion passenger kilometres travelled. Without know-ing how much European safety rates are better than world averages, this appears to suggest the business jet is safer than taking the car, and of the same order as travelling by train. Even with a higher world fatal-ity rate, shorter distances (say 330km, from Figure 30) travelled and assuming around eight passengers per trip, turboprops have a fatality rate of perhaps six per billion passenger kilometre, similar to that of motorway travel.
