Re: Heard of laser flare lights?

If you follow the link provided in post #17 by knuterikt it answers most of the questions people are posing here.

The signal lasers are different than the pointer lasers. They have a broader beam and are not harmful to pilots because the intensity of the beam is 1/1000th of the pointer variety, but still visible for 20 to 30 miles at night.

Re: Heard of laser flare lights?

I don't think Professor Schmidt's laser pointer has a battery that will last as long, or a beam large enough to really show up in the dark at distances of 20 miles. Haven't tried either, however.

Re: Heard of laser flare lights?

Are these ones getting pointed at CG helos actual rescue laser flares, or just laser pointers? I'd be interested to find out if they were, and if not, is there a difference between ones designed for rescue use vs a standard one (other than shelf life, waterproofing etc).

Re: Heard of laser flare lights?

So, if you want to be rescued, don't shine your laser at the helo!!! This guy (from a posting on page 2 of this thread) seems to have shone his off at an angle, away from the rescue helicopter, turning his light into a sort of aero beacon, showing exactly where he was:

Ths Coast Guardsmen involved with his rescue did not seem to mind him having and using a laser.

Coast Guard helicopter responding to distress call hit by laser

By Star-Advertiser staff

LAST UPDATED: 07:01 a.m. HST, Nov 27, 2013




STAR-ADVERTISER ARCHIVE
The Coast Guard said one of its helicopters was hit by a green laser while flying in the vicinity of Waimanalo Bay Saturday.

It's the fifth lasing incident within the last year involving Coast Guard Air Station Barbers Point.

The lased MH-65 Dolphin helicopter crew was conducting a search in response to a distress call when the incident occurred, the Coast Guard said.

Four crewmembers observed the laser sweeping the aircraft and one of the pilots was struck directly.

The Coast Guard is working with the Federal Aviation Administration and the Honolulu Police Department to investigate the incident.

Laser pointers can cause glare, afterimage, flash blindness or temporary loss of night vision.

The Coast Guard said it is a federal crime, as well as violation of most states' laws, to aim a laser pointer at an aircraft. If an individual is caught purposefully lasing an aircraft, punishment ranges from being arrested or having to pay a civil penalty of $11,000 for a single offense, to more than $30,000 if the individual has multiple offenses.

Re: Heard of laser flare lights?

I purchased the Greatland laser flare as part of my personal equipment when I sail offshore on OPBs (other people's boats). When I go offshore on an OPB I bring my own PFD, lanyard, PLB, personal AIS beacon and the laser flare. It's not that I don't trust the people I sail with, it's just that I prefer to have my own gear and to know that it's working as it should.

Re: Heard of laser flare lights?

I was at a safety at sea seminar last year. During one of the meetings a CG swimmer said the laser flares, especially the green ones, because of the night vision goggles, were very visible. The human eye is attracted to motion, so moving the laser would seem to be the ticket. Perhaps the CG has not issued official guidance to SAR crews.
Lasering aircraft is actually a huge problem, hundreds of cases every year. Those are usually high powered laser pointers, held on the cockpit of an aircraft, most frequently a hovering helo or aircraft on final. I tend to believe that a SAR crew on a mission would be able to tell the difference between a laser waved by a mariner in distress and a laser being used maliciously to "light up" an aircraft. I was peripherally involved in investigating laser incidents a few years ago. In all of the incidents I know of, the evil doer was on land, near a hovering helicopter (usually police or traffic), or on the approach path to an airport. The laser was maintained on the cockpit for a fair amount of time, not waved. The only "at sea" incident I ever heard of involved an infrared laser, a Russian "trawler" and a Navy sigint aircraft. I have been out of that loop for several years, but it's hard to believe the two scenarios could be confused.

In UK The Royal Yachting Association (RYA) have published this
RYA pressing for change in carriage requirement for flares | News | News & Events | RYA

Quote:
The RYA is pressing the MCA (Maritime & Coastguard Agency) to review the carriage requirement for pyrotechnic flares and to recognise the modern technologies that are now available for distress alerting and locating.

“In today’s modern age there is no compelling case to support the mandatory requirement of flares as a practical and useful method of initiating a distress alert and location” Stuart Carruthers RYA Cruising Manager.

Re: Heard of laser flare lights?

This makes it sound legal and more official. Anything further on USCG approval (or SOLAS?) since Feb 2012? At about $100 each, and lasting well over the 3 years any pyrotechnic seems to be good for, they seem like cheap insurance. Any other instances of their being used?

But there must be a difference between a laser pointer and a rescue laser?

In February 2012, the United States Congress passed into law HR658 authorizing appropriations for the Federal Aviation Administration (FAA) for fiscal years 2011 through 2014.

Included in the law is Section 311 "Prohibition Against Aiming a Laser Pointer at an Aircraft". Section 311 39A(c)(3) on page 56 specifically exempts "an individual using a laser emergency signaling devices to send an emergency distress signal."

Greatland Laser has sold its patented laser emergency signaling devices throughout the world for over 10 years. We have never had a safety issue with the products. Under the exception provided in this federal law, Rescue Lasers are legal to signal an aircraft for help in an emergency.

For an explanation as to why the Rescue Lasers are safe when a standard laser pointer can cause problems, please refer to "How Do They Work".
