Sikorsky Aircraft
continues to expand the S-92 flight envelope with new flight manual
procedures for European offshore operations that allow the aircraft
to either land safely on the helideck or continue flight if an
engine is lost during takeoff or landing.
Sikorsky added JAR-OPS 3 (Joint Aviation Requirements Operations
3 ) Performance Class 2e Elevated Helideck performance data to the
flight manual after completing 250 takeoff and landing maneuvers
with simulated engine failures on a fully instrumented
S-92.
The flight test data was incorporated into the flight path
computer simulation model to generate S-92 helideck performance
charts to meet expected future European Joint Aviation Authorities
(JAA) Operational Performance Requirements.
Most European-based twin-engine helicopters currently operate
offshore in accordance with Performance Class 2 data. Performance
Class 2 operations accept a limited period of exposure during which
the loss of an engine during takeoff or landing from a helideck may
result in a forced water landing.
The JAA is expected to require all twin-engine aircraft to meet
the Performance Class 2e criteria by 2010. With the addition of the
new Performance Class 2e data, the S-92 meets the requirement well
before the deadline.
Sikorsky notes that the S-92 provides unprecedented levels of
safety and reliability, including Enhanced Ground Proximity Warning
Systems (EGPWS) in all civil aircraft configurations. The S-92
helicopter is the first in the world certified by the European
Aviation Safety Agency/Joint Aviation Authorities (EASA/JAA) to the
latest and most rigorous safety standards. The S-92 was also the
first helicopter certified by the FAA to FAR Part 29 Transport
Rotorcraft, Amendment 47, the latest US safety regulations, which
mirror the European standards.
