Еще одна загадка
aillarionov — 24.04.2010
Это первый случай крушения
самолета с таким устройством, внедренным в конце 1990-х
годов. TAWS
содержит оцифрованные карты и
предостерегает громкой сиреной об опасном приближении самолета к
вершинам гор, радиовышкам или другим препятствиям. "С каким бы
давлением ни сталкивались другие пилоты, с какими бы погодными
условиями они ни сталкивались, ни один пилот еще не игнорировал
предостережение TAWS. Чем
так отличался этот самолет?" - задается вопросом эксперт по
авиабезопасности Джон Кокс.

The Polish jet... was equipped with a
safety device that warns pilots when they get too close to the
ground, the device's manufacturer said Tuesday. The existence of the device deepens the mystery
of why the jet struck woods and exploded as pilots attempted to
land Saturday at a Russian military airport, aviation safety
experts said. If the safety device was working properly, it would
be the first such crash of an aircraft equipped with the system
since its introduction in the late 1990s.
TAWS devices contain computerized
maps of the world and issue warnings whenever aircraft come too
close to mountain tops, radio towers or any other obstruction.
Accidents in which a functioning airplane flew into the ground had
been the leading cause of deaths around the world.
The devices, required on commercial
aircraft since 2005, have virtually wiped out such crashes. If a
jet gets too low, the TAWS issues a whooping siren and a recorded
voice demands pilots "pull up."
The fact that the jet had a TAWS
device "opens more questions than it answers," said John Cox, a
safety consultant and former accident investigator.
"I really would like to know what was
going on in that flight deck because no matter what kind of
pressure other pilots have been under or what kind of weather they
encountered, no pilot has ignored a TAWS warning. What is so
different about this plane that it would break that chain?" Cox
said.

A terrain awareness and warning
system (TAWS) aims to prevent controlled
flight into terrain… Statistics show that no aircraft fitted
with a properly enabled second-generation EGPWS
has ever suffered a CFIT accident.
Older TAWS systems, or deactivation of the EGPWS
system, still leave aircraft vulnerable to possible CFIT incidents. In April 2010, a
Polish Air Force Tupolev Tu-154M aircraft crashed near
Smolensk, Russia, in a possible CFIT accident killing all
passengers and crew. The aircraft was equipped with an older TAWS
made by Universal Avionics Systems of
Tucson.
