Powerline Warning PROTECTION YOU CAN HEAR

Powerline 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 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.

Powerline Detection System  Offers a Simple, Inexpensive Solution to Major Safety Concern  Significantly Reduces the Potential for Wire Strikes  Passively Detects Obstacles in a Head-Up Attitude  Double Pilot’s Time to React  Can Save Lives As Well As Dollars

The Issue  INADVERTENT OPERATING LIMIT EXCEEDANCE:  Excessive Transmission Torque  Excessive Exhaust Gas Temperature  Excessive Gas Producer Speed  Low Rotor Speed  Others  MOST EXCEEDANCES ARE INADVERTENT  COSTS:  Disaster – Accidents / Lives  Dollars – Equipment / Maintenance  Down Time - MMH/FH  Degraded Aircraft Availability Rate

Exceedance Warning  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

The Requirement  Significantly Reduce Inadvertent Operating Limit Exceedances  Reduce Accidents / Unscheduled Maintenance  Expand Pilot’s Situational Awareness  Improve Operator Safety Margins  Solution Must Be Practical and Cost Effective

Exceedance System Diagram

SFIC Exceedance Warning System  Provides Tactile Feedback Cues to the Pilot  Dual Speed Collective Shaker  Limit Exceedance Computer  Prevents Inadvertent Exceedances from Occurring  Pilot-In-The-Loop Decision Making  No Hard or Soft Stops  Complete Freedom of Collective Movement

How It Works – Human Factors  Pilot’s Response - Instinctive  Lower Collective (Reduce Power) if Appropriate  Result  Pilot Has the Information Needed to Make the Best Decision in a Timely Manner  The Pilot Knows When a Limit Is Being Exceeded  The PILOT DECIDES What To Do

Collective Shaker  Dual Speed Shaker Controlled by the Limit Exceedance Computer  Low Speed Shaker - Warning of an Impending Limit  High Speed Shaker - Alert That a Limit Has Been Reached or Exceeded

How It Works – Collective Shaker

How It Works – Exceedance Computer  Continuous Real Time Monitoring  Transmission Torque  Engine Exhaust Gas Temperature  Engine Gas Producer Speed  Main Rotor Speed  Others  Dual, Programmable Trigger Points

Exceedance Computer- Diagram

System Characteristics  Shaker  1.1 to 1.4 lbs  2.5” x 4” Approximate Envelope  < Amp (1 Amp Surge)  Exceedance Computer  8”L x 5”H x 2.5”W  2.5 lbs  Waterproof  Dustproof  28 < 1 Amp  Reliability / Maintainability  Reliability > 22, Degrees C  Extensive BIT  Maintenance Diagnostics via Laptop  R / R Time < 10 Minutes  Qualified to DO-160D

Exceedance Avoidance OPERATING LIMITS YOU CAN FEEL  Significantly Reduces the Potential for Operating Limit Exceedances  Prevents Exceedances Rather Than Recording Them “After the Fact”  Reduces Unscheduled Maintenance  Improves Situational Awareness- “Eyes Out Of Cockpit”  Increases Operator Safety Margins  Is Effective and Simple to Install

Safe Flight Instrument Corporation  Powerline Detection -Doubles Pilots Reaction Times -Saves Money and Lives -Significantly Reduces the Potential for Wire Strikes  Exceedance Warning -Is Inexpensive -Is Easily Installed -Will Increase Aircraft Availability Rates -Will Drastically Reduce Maintenance Costs
