Glider Safety
The following is the first of a series of newsletters to be sent to
subscribers to my popular newsletter. It is a topic I presented at the FAA Safety Center in Lakeland Florida. If this is of any interest to you, please go to our web site www.eglider.org and click on the link on the right side of the home page to subscribe. Tom Knauff A TEN-YEAR REVIEW OF GLIDER ACCIDENTS You will find information about glider accidents on the following web site: http://www.ntsb.gov/Aviation/Aviation.htm This series of newsletters will review: Accident causes. Where they are happening. What you can do. Glider pilots are generally: Intelligent Educated Mature Financially well off You would expect glider flying to be safer than most other activities. Which is more dangerous? Flying Gliders? Driving Automobiles? A common statement is: “Driving to the gliderport is more dangerous than flying in a glider.” Unfortunately, this is not true. Common Automobile Accident Factors Night driving. Alcohol, drugs. Minimal training. Distractions. Speeding. Heavy, close traffic. Young/old drivers Flying gliders has very few of these accident-causing factors. You would expect glider flying to be safer than driving. However, statistics show glider flying (USA & most countries) is much worse. FATALITIES PER THOUSAND Gliders: Approximately 1 in 2,000 Autos: Approximately 1 in 6,000 Ten Year Glider Fatalities (USA) Year 2009 8 2008 3 2007 6 2006 4 2005 6 2004 7 2003 6 2002 6 2001 6 2000 5 Total 57 fatalities. 5.7 per year. The thirty-year average is 6.1 fatalities per year. More to follow. Tom Knauff |

Per thousand what? Is this registered gliders, certificated pilots, hours flown, miles flown...? thanks Andy |

If it wasn't dangerous it wouldn't be any fun.

wrote If it wasn't dangerous it wouldn't be any fun. I hope you say that mostly in jest; otherwise, I say, Bull-bleep! To some, that may be the reason they fly, but that sure isn't the reason many or most fly. I want to be old and gray, and flying all the way till I can't see straight in my upper 90's, at least! -- Jim in NC |

I wonder how these calculations take into consideration the hours spent on both activities. After all, one spends a lot more time driving than flying a glider (although there may be a lucky few for whom this does not apply).

Perhaps I have been sheltered,
But I have never heard the claim the flying gliders was safer than driving. What I have heard and my amateur review of the fatality numbers per hour seems to confirm is. Flying commercial airlines is safer than driving. GA flying about the same as riding a motorcycle GA flying can be as safe as driving if you eliminate low flying and bad weather flying. Glider flying is more dangerous than GA flying, I am unsure by what factor. ************* Of course there are many ways to look at the numbers. One can count fatalities, injuries or accidents. One can count per vehicals or per person. Just those two variables give about 12 different combination's of ways to count the numbers, However I am looking forward to Tom's Analysis.

My favourite are the pair of statistics from the '70s, probably still true today: 1 landing in commercial airliners is becoming safer 2 landing in commercial airliners is becoming more dangerous 1 is true for accidents per landing 2 is true for proportion of accidents while landing |

This seems to be quite a common attitude toward glider flying. I wonder how much better the glider fatality numbers would look if the cases where the pilot was dead, or otherwise medically incapacitated, prior to the accident were eliminated. Several US fatal accidents in the past few years seem to fall into that category. Is there a case for requiring a medical certificate for SSA sanctioned contests? Andy |

Right. Let us inflict more restrictions on ourselves. For the
children of course. If it is a good idea for contests then it is good idea for everyone... Is there a case for requiring a medical certificate for SSA sanctioned contests? Andy |

Is there a case for requiring a medical certificate for SSA sanctioned contests? Andy I am unaware of any third party being injured from a glider accident resulting from incapacity of the pilot. After all, sailplanes are pretty light and don't burn. However, it's pretty unsettling to the rest of us. I was at Parowan last year and was also personally affected by one such incident. You'd get my vote for requiring a medical certificate. You could also make a case for requiring a medical certificate for pilots instructing and carrying passengers, but again, I doubt that there is much of an accident database to support the need for this.
