NASA Releases Cryptic Airline Safety Data 148
An anonymous reader writes "NASA released part of a controversial study about air traffic safety Monday. The space agency spent $11 million on a survey of airline pilots. Agency officials were so disturbed by the findings that they intended to destroy the information rather than release it. But at an October congressional hearing, NASA administrator Michael Griffin changed tack and said the agency would release its findings. The research shows that safety problems occur far more often than previously recognized. NASA has been criticized however for not providing 'documentation on how to use its data, nor did it provide keys to unlock the cryptic codes used in the dataset.'"

during the take-off and landing stages in both cases the secondary systems have to kick-in because either the
pilot was pulling up too fast and as a result would have hit the tail on runway for take-off, or they were landing
with an awkward angle.
In both cases the system automatically kicks in and "attempts" to rectify the situation. The trouble is there is a
calculation it does relating to a "projected" state of the aircraft and what kind of counter maneuvers have to be
executed in order to get out of that state.
If it decides the number or the sensitivity of the maneuvers is beyond what a human can do within the necessary
time span it kicks-in and helps out - that fact is recorded on the CMU and on the blackbox most often than not its
ignored by the FAA and the airlines. for the most part the bells and whistles occur when there is a possibility of
a mid-air collision or if the aircraft is descending at a rate that not considered safe.
As for cruise, when considering a 747 traveling in bad weather with flaky radar at about 850km/hr the distance traveled
in 10secs is roughly 2.3km, in that 10seconds the pilots may be required to execute a series of very complex maneuvers,
the unfortunate situation is when someone with years of experience freezes or makes the wrong decisions under pressure/stress,
such human weaknesses make these systems a necessity.
The point I wanted to make was that the TCAS data collected both in the US and Europe are not being used to better
train/filter-out pilots.

Why is it that you can't see a difference between internally investigating and correcting something as a routine review process and publicly declaring an entire industry to be rife with major safety issues and destined for disaster?
Clearly they are two different things.
