PLB brings speedy rescue to pilot trapped in trees
By Mike Collins, AOPA A Pennsylvania pilot is crediting his personal locator beacon (PLB) with his rescue only two hours after his glider crashed in rugged mountains near Altoona, Pa., May 9. http://www.aopa.org/aircraft/article...raccident.html |

What seems really strange is the the rescurers didn't have a simple,
inexpensive, GPS so that they could zero in on the pilot quickly. The narrative indicates that the pilot had to guide them in via sound. Even cell phones now have GPS. This should be required equipment. |

It is also at least plausible that an alert process can be started before a triangulation fix established. If the ground SAR crew had 121.1 direction finder that may also have helped triangulate on the PLB 121.5 Mhz beacon (all 406 Mhz ELTs and PLBs also have 121.5 Mhz homing beacons), but with heavy foliage/steep terrain that may have been more work/slower than the airhorns.

![]() “Our sport, like many others, has become very technology heavy,” he said. “With the personal devices, I made the decision that the couple of hundred dollars that you spend could really pay off.” Dutka said he “absolutely” felt that investment paid off Sunday. Money well spent. Hopefully he'll spend some on recurrent training too in order to avoid getting into the same unfortunate fix again. |

Poor weather conditions, close to the mountains ridges, no outlanding
fileds and still having water ballasts full of water? Strange........ |

Darryl Les’s comments in the AOPA web article are consistent with the experiences with both the Peter Masak and Dale Kramer searches. Although very high quality information (e.g. coordinates, elt signal, knowledge of route being flown) may be available, there is a gap in the ability of local non-aviation rescue (and even CAP) to accept and/ or use it effectively. Had Les not been able to respond to the sounds made by the rescue team over his cellphone, it would have probably taken much longer to find him as there is no indication that his coordinates were either communicated to the rescue team or that they had the capability to use them. However, I do not know whether SARSAT actually got GPS coordinates from his PLB or they just estimated coordinates from the PLB signal (a 406 Mhz elt signal without GPS determines a search area of about 2 miles radius). This reinforces the advantages of having something with you that makes noise (elt, whistle, bike horn etc.) that is either automatically activated or on the front of your chute. |

"Poor weather conditions, close to the mountains ridges, no
outlanding fileds and still having water ballasts full of water? " was not in the article anywhere Strange? Not when you consider the pilots actual comments... "winds were pretty strong" "skies were overcast" "He said he was ridge soaring when his glider stalled and spun into the side of a mountain" were some of the pilots and authors comments, so I'm not sure what people are getting at here. Sounds like he is genuinely grateful and amazed to be alive after an admitted stall/spin. |

Extract out of the provided link : "He was flying lower and lower, without finding lift, and had not dropped his water ballast—which increases stall speed. " The question I have about this is the effectiveness of the different alert devices while upside down. Would the SPOT get a message out, would the PLB? Where I fly there would be no cellphone coverage and no way to get a fire truck with an airhorn, so it would be SPOT or PLB and a very long wait. Brian |
