FLARM in Stealth Mode at US 15M/Standard Nationals - Loved It!

Note that other planes will NOT have any more warning of you. This has caused issues in the UK, and as a result Stealth is no longer required for competitions. Which other planes? Which "more warning"? Please explain. P3 |

Other Flarm users. If you are in Stealth you give no more warnings to other users than you receive. So non-stealth gliders will not see any more than your fellow competitors.
This has the unfortunate effect of causing gaggles to 'appear' with very little prior warning. So... a fast moving powered aircraft that happens to have Flarm will have seconds worth of warning that you are about to collide which may not be sufficient. I'd be concerned about the liability issues if this was to happen because you had degraded your collision avoidance systems - especially in the US! |

The best pilots always win, regardless of stealth mode or not.

Stealth mode doesn't change the warning mode of flarm, at all. It does change the tactical display for aircraft that are not in conflict. A fast moving powered aircraft, properly configured, should get plenty of warning from thermaling gliders. And vice versa. -Evan Ludeman / T8 |

FLARM in Stealth Mode at US 15M/Standard Nationals - Loved It!
This was my first experience with FLARM. I had prepared myself for a significant change in tactics vs. what was the norm when I last flew a nationals in 2010 but I have to say that I'm a believer now.
As has been said, FLARM in stealth mode enhanced safety without changing fundamentally the skills required to do well in a contest. Granted, on a few occasions FLARM alerted me to another glider a short distance away under the same cloud that proved to be climbing faster. But this zone of visibility was fairly small. On the other hand, I received several warnings of gliders unexpectedly coming into a thermal rapidly from an angle that were quite useful and were received in plenty of time to take action. I was using a PowerFLARM Portable with the internal readout. I'm told that this device as well as the "core" unit can drive a FlarmView or other readout that provides more data on the gliders within range; e.g., contest ID and climb rate. That's potentially useful information. I don't know where you draw the line but even with this enhancement, FLARM like a decent compromise between the safety benefits and the degradation in skill required to fly competitively. My decision now is whether to buy a PowerFLARM (the one I used was very generously loaned to me by fellow pilot Bill Nockles)--new or used--or the "core". Is it true that there have been multiple configurations/types of PowerFLARM portables over the past few years? Chip Bearden ASW 24 "JB" U.S.A. |

A fast moving powered aircraft, properly configured, should get plenty of warning from thermaling gliders. And vice versa. Warning is not what you want in that situation it is tactical awareness. But then almost every glider pilot is convinced they are being followed so Flarm is obviously a tool to make this easier |

I flew the PAGC this year in TN (Thanks, Sarah) where we used FLARM extensively as tactical device. I felt it changed the nature of the contest significantly.
It was my idea to go stealth at the Std/15m Nats this year at Harris Hill. I flew the contest as well and had no complaints personally or from any other competitor- other than some had trouble configuring initially. All warnings were spot on and the unit became a collision avoidance only. Warnings from fast movers always over ride the 2km and +\- 300 m vertical limitations. I'm glad we did it so we can have an informed discussion on this important topic in this year's opinion poll. XC |

With a proper display you always know where the other gliders are around you, no need to wait for the alarm to take evasive action. And you still have that same situational awareness for any planes near you. You just are not told who it is and how fast they are going up or down. The only thing lost is the ability to change where you go based on information about what the air is doing at some distance away from you. So you get a glider symbol on the display with no contest number and no rate of climb? What about altitude? I have found the rate of climb indication pretty useless, too coarse and discontinuous to be of use for leeching. If you can see the glider you can better assess their relative climb by eye. But position and altitude are necessary for situational awareness. |

You get the glider symbol and relative altitude. My experience was actually an aural warning first - " Traffic, one o'clock high". Because my eyes were outside the cockpit. There was no reason to look at the scope.
