My connections with you have influenced my thinking and understanding of the
world. As a result I give explanations to (safety)events from a perspective
that is supported by some of your inputs in the last years. I have a so far
untested model of a specific safety event that I would like to share with
you and I hope that you will give feedback.
The event is a take-off from a taxi way. You will understand this is a
unwanted event since this action might have resulted in a collision or
runway excursion if a take-off abort was executed. This is the data I can
share with you: http://avherald.com/h?article=4272f72c
We are very surprised this could happen at our home airport. A very
The model I want to test goes like this. Airlines are under pressure for
survival. It is hard to make money with air transport. This is the general
situation for the last several years. This macro situation translates via
management influences to be safe, but also efficient, on time, minimum fuel
etc. Very good to understand under the described conditions. Pilots, as
professionals, find pride in operating safe, efficient, on time etc. This
results in a kind of behavior that may breakdown in unexpected situation.
The drive for efficiency leads to a maximization of use of possibilities
that are favorable to the flight, such as accepting a shortcut offered by
ATC (who also want to support efficient traffic flow). The efficiency driven
anticipation of possible (favorable) futures may lead to a situation where
no slack is left to deal with unusual situations. Since the system was
operating near the boundary of the envelope of maximum efficiency it cannot
deal with the unexpected. This then can result in unusual breakdowns,
Can you support me with theory or correct me with this explanation of the
taxiway take-off ?
I can't share all I know about this event but I can test your suggestions on
the data I have access to.
Thanks very much,
