Airborne PA System on Helicopter

"I may sound like I'm a rep for Power Sonix when you read this, but I'm not. We had some old (NAT) PAs in our old aircraft that sounded like Charlie Brown's mother talking ("Wah wah wah"). And that was at 300 feet AGL and 20 knots. We fgured that making PA announcements were some of (the) riskiest missions we performed because we had to fly so low and slow for people to understand what we were saying. When we replaced the aircraft we also replaced the (NAT) PAs with Power Sonix.

I cannot begin to tell you how much better they work when we use them. We now make PA announcements at 800 feet AGL at 50 knots and people hear us clearly and at signifcant distances. Very impressive systems and well worth the money. Kev"
