Factors influencing misaligned take-off occurrences at night
Factors influencing misaligned take-off occurrences at night

Summary
On 3 July 2009, the Australian Transport Safety Bureau (ATSB)
was notified that a SAAB Aircraft Company 340B (SAAB), registered
VH-ZLW, had commenced its take-off roll along the runway 25 left
edge lights at Sydney Kingsford Smith Airport, New South Wales.
This was one of three occurrences over the previous 2 years that
involved aircraft commencing takeoff on the runway edge
lighting.
In addition, within the previous 2 years the ATSB investigated
two other occurrences involving pilot misidentification of runway
alignment cues or lack of those cues during takeoff. All five
Australian misaligned take-off and landing occurrences involved
aircraft with weights greater than 5,700kg and three of the six
occurrences involved scheduled regular passenger transport (RPT)
operations. The remaining two occurrences involved charter
operations.
This research investigation examined each of these occurrences
and relevant international occurrences to identify the common
factors associated with misaligned take-off and landing
occurrences.
After reviewing the Australian and international occurrences,
eight common factors were identified that increased the risk of a
misaligned take-off or landing occurrence. The factors included:
distraction or divided attention of the flight crew; confusing
runway layout; displaced threshold or intersection departure; poor
visibility or weather; air traffic control clearance/s issued
during runway entry; no runway centreline lighting; flight crew
fatigue; and recessed runway edge lighting.
To foster safety awareness, knowledge and action, the ATSB
developed a pilot information card to help flight crew identify
factors that could increase the risk of a misaligned take-off or
landing.
