The five year moving average analysis has and will continue to provide a realistic ‘measure’ of performance. Moreover, until 2009, annual data did not warrant particular comment or high-lighting. As will be evident from the summary below, such is not the case for 2009.
The business aviation global fleet increased by 4.4% in 2009, comprising an increasing in jets
of 5.4% and turboprops 3.1%.

Flight hours in 2009 increased by 3.1% overall, with jets accounting for an increase of 2.6%
and turboprops a decrease of 4.3%.

In calendar year 2009 the number of accidents involving business aircraft (jets and turboprops)
decreased by 27.9% (101 cf 140) from those in the previous calendar year.

Fatal accidents decreased by 34.1% over the same period.
Accidents involving jets decreased by 44.2% (24 cf 43) and turboprops 20.6% (77 cf 97).

Table 2.3a
(Note: These are derived figures based on flight hours and sector durations typical for each category of jet and turboprop aircraft.)

2.4 Organization of the Community
Business Aircraft operations are classified into three (3) separate categories:
1.
Business Aviation Commercial
Aircraft flown for business purposes by an operator having a commercial operating certificate
(generally on-demand charters).


2.
Corporate
Non-commercial operations with professional crews employed to fly the aircraft.


3.
Owner Operated
Aircraft flown for business purposes by the owner of the business.

 

(Note :  Consult IBAC for formal definitions of the three categories. Two additional classifications are included in the Breiling Report, namely Govern-ment (public operations) and Manufacturer aircraft.  These are not, by their use, considered to be “business aircraft”, but are included in the data for completeness.)
