2.3 million engine flight hours
30 reported bird ingestion events
(including a bird more than 3 lbs)
All fan blades remained
fully servicable

8. Swept fan blades add
More than 2000 lbs (8.9 k N)
Additional thrust
SWEPT FAN BLADES
also provide better fuel burn

14. Tests by Lucas Aerospace
Ex Pan Am
Tests by Lucas Aerospace
Wings needed re-strengthening

15. ETOPS
EXTENDED
TWIN OPERATIONS
OVER WATER

16. FAA Type Design approval
confirms that the engine/aircraft combination
has the reliability to conduct ETOPS operations
up to 180 minutes flying time from a primary
or alternate airport.
ETOPS approval provides
airlines much greater route-scheduling
flexibility as it allows twin-engine aircraft
to service routes traditionally reserved for
three- and four-engine aircraft.

17. MOST IN FLIGHT
SHUT-DOWNS ARE
CAUSED BY
PUMPS,
TUBES AND SIMILAR
EXTERNAL COMPONENTS
