PROTECTION YOU CAN HEAR

Powerline DetectionPowerline DetectionPowerline DetectionPowerline Detection

Challenge Protect Rotary Wing pilots from the “invisible

hazard” of power lines

Safe Flight Solution We developed a powerline detection system that

aids pilots in reducing risk of power line strikes during low level operations

Features Provides an audio alert, which clicks like a

Geiger counter, is heard through the audio system and increased in frequency as the power line gets closer.

Powerline Strike Risk ReductionPowerline Strike Risk ReductionPowerline Strike Risk ReductionPowerline Strike Risk Reduction

On Average: 60% of wire strike victims failed to see the wire 75% of all wire strikes destroy the aircraft Average reaction time between seeing the wire and

meaningful action to avoid is 4.6/5.0 seconds (The Powerline Detection system increases the reaction time to 10 seconds)

Two wire strike accidents occur in the United States each week

One fatality occurs every seventeen days Only about 10% of the wire strikes that occur are

recorded There are 4.6 Million Miles of Powerline in the U.S.

Powerline Strikes are one of the greatest hazards to both civil and military helicopter operations.

Challenge Provide rotary wing pilots with a tactile warning when

operating limits are approached

Safe Flight Solution We designed and produce collective and pedal stick

shaker systems warning pilots when they are approaching various operating limits

Features Provides Tactile Warning of when Operating Limits are

being approached or exceeded Such as: Transmission Over Torque, EGT, Rotor Speed
